Pros: When I am not sure how to translate some objective-c code I can get the converter to do it and I usually get code that is either completely compatible or needs a few tweaks to remove the errors/warnings.

Cons: It sends back a lot of lines like 'let value = value' to do optional testing. I don't like setting a value to itself and tent to rewrite all of those lines.

Overall: I'm converting a full app from objective-c to swift and I'm finding this a very good tool to finish a lot of the code quickly. Then I just need to go back through the code to make sure it is operating how I need it to. Sometimes I don't examine the new code as closely as I should and get unexpected outcomes. This is because I am relying on the translation to much. It does such a good job I'm not testing my code close enough and get stung when the result is undesired.

Thanks Dave for your awesome review!

As we are always willing to make the product better, I am always open to your suggestions here.

1) Which pattern(s) do you commonly use for unwrapping of optionals?

Variable shadowing like `if let value = value` is a common practice to unwrap optionals in Swift.

We are considering switching to generating `guard let` statements in the future, but this is more difficult and possible only in a subset of cases:

2) The Advanced Project Converter (included in Swiftify for Xcode app in the macOS App Store) allows you to easily compare (original) Objective-C and (converted) Swift files:

Hope that would be helpful.
Thanks again for your time, and don't hesitate to follow me up on the above questions - I am definitely willing to address them addressed as much as possible!

Pros: easy copy paste options, option to select different swift versions. support for xcode as plugin and project conversion.

Cons: copy paste limit on website. no support for dark mode. should add support for other editors.

Overall: I love it and its my first choice to convert code. Easy to use and understand. one click operation.

Vendor Response

by Swiftify on August 09, 2019

I appreciate your feedback!

1) Indeed, the free version allows converting code blocks up to 2 KB. This should cover occasional usage like converting one method at a time, however.

If you need more, you may upload one or more zipped file(s) on the Converter -> Project page. The rates to pay for an individual conversion are pretty low, so that should be sufficient for occasional usage.

2) The macOS app fully supports Dark Mode.
We are featured in the Apple's list of Apps with Dark Mode support and on https://darkmodelist.com/.
Could you suggest where are you still lacking the Dark Mode support?

3) Which other editors (s) would you like supported?
We could consider your vote for our later development.

Pros: 1) It is very easy to use.

2) Any jr. programmer can use it from day one

3) It converts anything that is Objective-C to Swift, in a very timely manner, without bottlenecks.

4) I like the fact that we can try it out under the free version and test before we decide to buy it. P.S: We ended up buying it for one of our projects that required we convert an Objective-C SDK to Swift.

5) It has an Xcode plugin.

Cons: Conversion sometimes is not 100% accurate, but it is accurate enough for our team. I honestly don't think there are any cons about the software. It was be used on the web, and on Xcode as a plugin, which honestly was perfect for our team.

Overall: The overall experience was "Oh wow, didn't knew they had something like this out there". At first I was a bit skeptical because I had tried other converters that were not accurate enough for us. But after a couple of days of converting small swift functions, I was convinced it would be ideal for our project.

Regarding workspaces and mixed Objective-C + Swift apps, they are indeed supported in the Advanced Project Converter, which is the part of "Swiftify for Xcode" app in the Mac App Store.

By default, the app updates all projects in the workspace if needed.
However, you can manually choose which project(s) from the workspace should be processed or not:
https://support.swiftify.com/hc/en-us/articles/360028372231-Update-Xcode-project-files

We suggest that you work with a single project at a time by unchecking unrelated projects to constraint changes made by Swiftify to your selected project only.

Pros: I liked how easy it was to upload files and received the converted version.

Cons: I liked that the free version was a bit too restrictive for general developers of companies not generally prone to invest in tools like this when suggested by their team.

It would be great to have some sort of infographic to sell the idea to the business directors in order for developers to convince them to invest in this tool, but in terms of the impact it has on the budget necessary for projects.

Overall: We are currently migrating a 6 year old Objective-C project that needs to be refactored using Swift because of an external library implemented only for this new language. Using a bridging header or thing like that is not a possibility. We used this tool to convert some files in order for the new developer to get a grasp on how the classes would look like after being converted. It was a nice tool to use. However, we were not backed by the technical direction to keep on using it more extensively.

Pros: I liked the fact that I am able to explore my entire project, as in Xcode. I am able to select groups of files to convert, and add newly generated Swift files to my project file. The learning curve that exists when moving between languages was definitely cut in half with the use of this tool.

Cons: I did not like the constant prompts to upgrade after certain uses of the software.

Overall: When creating a new project that has an optional third-party library, framework, or class in Objective-C language, the conversion from Objective-C to Swift is very accurate, and often updates with the modern version of Swift. This is very helpful for varying versions of previous files that one may encounter.

Pros: Saves you alot of time. As someone who knows both Objective C , as well as Swift, this tool saves you a great amount of time when dealing with projects that are being converted from legacy code. The output tends to almost always be correct.

Cons: Can't say there are many cons. The only thing I can think of is that there is no way to convert multiple files at once.

Vendor Response

by Swiftify on July 04, 2019

Just wanted to say "thanks" for your awesome review!

Regarding the conversion of multiple files, while Xcode does not support this (Apple have not made it possible for Xcode Extensions to access anything beyond the currently edited file), here are the options:

1) Zip multiple `.h` and `.m` files and convert at https://objectivec2swift.com/#/converter/project/

2) Use the Finder Extension (included in the "Swiftify for Xcode" app in the App Store) to select and convert multiple files in Finder;

3) Use the AppCode plugin to convert pairs of `.h` and `.m` files from within the IDE (which supports such functionality, unlike Xcode).

Don't hesitate to follow up with me if you have additional questions!

Could you please elaborate what (in your opinion) could make the product more user friendly?
Which of the components (web based converter, Xcode Extension, Advanced Project Converter) were you using most?

Regarding the conversion speed, I'd be glad to hear what is your country / location and in which cases you find yourself waiting for too long.

Pros: Really helpful when you don't want to add a new feature to the old Objective-C code.

At the same time, quick revitalization to the newest Swift gives a boost in implementation performance.

Cons: I don't need a subscription as I am using this service quite rarely for the single files. In my case, the pay-as-you-go model could fit much better.

Overall: Sometimes, I am converting legacy classes written in Objective-C to Swift.

I really appreciate your awesome feedback!

If you don't need a subscription, we actually have a Pay As You Go plan that you could use.

Just upload your project at the Converter -> Project page and pay for an individual conversion here:
https://objectivec2swift.com/#/converter/project/

We are still in process of figuring out the best pricing model so your suggestions are definitely welcome.

Pros: Super easy to convert a lot of my older ObjC code to swift.

Also, has done a great job keeping up with the latest version of swift.

Cons: Suggestion: don't autofill the left ObjC panel with sample code. It would be quicker to start with a blank panel to paste in my code.

Overall: Overall, this tool has be incredibly valuable in helping me learn swift.

Vendor Response

by Swiftify on July 15, 2019

Hi James,

Thanks for your awesome review and suggestions!

One of the reasons we've been filling the left pane with the sample code is to demonstrate how one can join contents of interface and implementation file(s) into the Swift output.

While you are encouraged to use the Xcode Extension (which is just more convenient, and won't fill in any sample code), I'll think about changing the left pane to a very minimum, or just blank code!

Great app!

Pros: Pretty decent accuracy when converting Obj-C to Swift. *Much* faster than converting a ton of code by hand

Cons: Sometimes code doesn't translate properly or there are other modifications that are needed.

Overall: Objective-C to Swift converter has been a great tool to use at work. We have a legacy app written in Objective-C and a new app written in Swift which uses very similar functionality as the existing ObjC app. When I need to get some Objective-C code translated into Swift fast Objective-C to Swift converter is my first go to tool. Sometimes of course the code doesn't translate properly or just isn't translatable to Swift but this tool will give you a decent head start if you know how to modify your logic / syntax and are willing to do some proper Googling to fill in the pieces. No, this won't convert your existing Objective-C app to Swift in one go, but it's a great tool to use to update Objective-C code to Swift or translate it for use in a new Swift app. Thanks for providing this and keep up the great work!

While a 100% correct conversion nearly impossible to automate, we aim to save your time and efforts.

Pros: The best part of this software is that its convert the code in fraction of seconds, sometimes the codes do face some error because swift keeps upgrading and so is this software.

The pros are as follow :

It makes switching of code easy.

Almost 98% of time it does convert the code well

Its available on both web as well as Xcode extension.

Cons: Cons :

Not all code are convertible , for eg : Alamofire is a pod developed by a third person and if you use this code in swift and try to convert into Obj C it will either show the same code or may not change. (Still it just happen only 2% of time and I am sure that its developer will get this solved soon)

Overall: Overall I recommend this to everyone who wants to try their hands on iOS/ Mac development. Its a basic tool for all developers working for apple development.

Thanks for your thorough feedback!

Good timing to ask. We have just rolled up very improvements related to value types like String/Array/Dictionary/Set/etc.

Since this week's update, Swift collections of value types are being passed by reference (using `inout`) keyword, and `&` operator is used to pass the related argument.
Also, we no longer create shadow variables for method parameters of collection types that need to be writeable.

See this sample (switch between Swift 4.2 and 5.0 to see these changes live):
http://swiftify.me/r54g2s

Since we have just rolled up these changes, I'd appreciate your time to check if your feedback has been addressed ;)

Pros: It's good for quickly translating objc into swift.

Cons: You have to go over almost every line of code it translates and fix something. It still doesn't do simple things like adding "override" before viewDidAppear in viewcontrollers for example. Also, it's way too expensive. One day the price just doubled and they told me they never changed the price since they launched so it's ok. It's not ok, it's way overpriced.

Vendor Response

by Swiftify on August 02, 2019

First of all, thanks for trying Swiftify and your constructive review!

Regarding your comment on adding the `override` keyword. The `override` keyword is properly added, but of course, only if your class derives from UIViewControler (or a superclass that also defines this method): http://swiftify.me/huz23h

Thus, you have to include the whole class declaration in the conversion for this to work properly.
If you convert a selection in Xcode, and the selected text does not include the class declaration, the converter would not know what the parent class is.

As regarding pricing, we are still looking for the best pricing model and I'll consider your feedback.
If you don't like the subscription model, you can pay for an individual conversion by uploading your zipped files or project at https://objectivec2swift.com/#/converter/project/

Anyway, I hear your feedback and I am open to any suggestions to make the product even better.

Pros: It works well, for what it does, and the publisher keeps it updated, so that, while reviewing its results, I always learn a few new things about the latest version of Swift :)

Cons: It's not quite as smart as a human Swift pro. The last time I used it, a few months ago, I saw that in some places it would employ a bunch of unwraps in a block of code instead of enclosing the whole block in a guard/let. But that's understandable, and after you see it a couple times you know what to look for

Overall: I almost bought a subscription a couple times, but did not because, so far, I've not had a substantial project to convert, so I'm able to skate by with the free version. But if I ever do have such a substantial project to convert, I would buy a subscription.

Pros: It's very easy to convert code, especially legacy Objective-C code from others' old projects that I'd like to use in my Swift projects. I have to make very few changes to turn what Swiftify produces into working code, and even then, it's usually just changing obscure Cocoa class names to their Swift equivalents.

Cons: I didn't like how you had to register an account to convert more than 1KB of code; the only reason I made an account was to get around this limit.

Pros: Xcode integration and the ease of use fantastic. Also, the team at Swiftify is keep the updates coming to conversions keep getting better and more accurate.

Cons: Getting started with the API key was a bit confusing, but once you're set with that it's super easy. Considering this takes away a significant portion of the hassle of migrating to Swift, I can't complain much.

Overall: I'm a new coder learning Swift and I've found that I learn much faster by converting some of my favorite open-source apps. Many are written in Obj-C so that's obviously a lot of work, but great practice. The converter is like the answer page at the back of the math book. It helps me find the correct solutions when I'm learning.

Pros: Saves tons of time in converting to Swift. I used to have a policy of writing new code in Swift, but maintaining existing code in objective C, which meant a slower migration. Now I'm willing to convert old code, because it's not such a big time investment.

Cons: It has some quirks about how it handles certain scenarios. Also the finder interface just stopped working, and can't find much online troubleshooting help.

Thanks, Tim for your valuable feedback!

I am more than willing to hear you suggestions about quirks that you have mentioned.
Either reach to me personally at alex(at)swiftify.com or report any issue(s) at our GitHub Issue Tracker:
https://github.com/Swiftify-Corp/Swiftify

Regarding the Finder Extension, initial suggestions are:
1) Look for the "Swiftify" menu both on the top level of file or folder context menu, or under "Services".
2) If this cannot be found anywhere, a clean reinstall of the app from the macOS App Store usually helps in such cases, because this is the way to re-index extensions.

Hope this helps. I'd appreciate a quick follow-up if my suggestions resolve your issue.

Thank You for such an easy to use tool

Pros: We've been programming in Objective-C since Mac OS X 10.2 and we were looking for a tool to convert our old code from way back then to Swift and this is the only tool that could do it.

Cons: The only problem is it cannot convert carbon to cocoa. At least not in the version we used.

Pros: Transforming this Obj-C code to Swift is both educational and time saving.

I will either use the converted code pretty much as is, or use it to lean how to do something before starting new code.

Cons: 1. The resulting translation is sometimes very Objective-C like and not the best Swift-first implementation. That's to be expected.

2. The free conversion via the website is very restrictive in terms of character count. This can normally be overcome by breaking a function into fragments and converting them one at a time.

Overall: I am generally transforming single functions or classes from a legacy project or code snippets from Stack Overflow into current Swift.

Pros: As it's an easy to use software there's not much to be said except that the convert function is really simple really great to use, it "just works" it's almost as if magic, I just have to C/P my code and we're good to go

Cons: The limit is really low, I think that's the biggest downside, it takes time to convert a big code because I have to past it chunk by chunk, increasing the limit even by some ko would be perfect

Pros: Great trial features allow you to convert single classes quite easily

Cons: Converting single classes sometimes gives you very weird looking code that needs optimisations before it looks like proper Swift. Still better than having to rewrite everything.

Overall: We converted several parts of an older code base to integrate it into a rewrite of the basic project. This was easier with Swift Converter since it saved us from having to rewrite big parts of our code.

Pros: I liked that it required only a registration to be able to convert more lines of code instead of being paid. Was really easy to use, just a converter which really works great by converting the code to the latest swift!

Cons: Registration part, but let's say that it was really quick, so it didn't bother me, as I thought it would take me lot of data, but you can just signup quick!

Overall: Anytime I got a solution working in objective c and you want to immediately try it in swift this is the right tool for it. No time spent anymore doing it manually :)

Vendor Response

by Swiftify on July 08, 2019

Thanks for your valuable feedback!

Good timing to ask. We have just rolled up very improvements related to value types like String/Array/Dictionary/Set/etc.

Since this week's update, Swift collections of value types are being passed by reference (using `inout`) keyword, and `&` operator is used to pass the related argument.
Also, we no longer create shadow variables for method parameters of collection types that need to be writeable.

See this sample (switch between Swift 4.2 and 5.0 to see these changes live):
http://swiftify.me/r54g2s

Since we have just rolled up these changes, I'd appreciate your time to check if your feedback has been addressed ;)

Regarding block related code, would be awesome if you provide a sample. Either email me at alex(at)swiftify.com or report it at our GitHub Issue Tracker: https://github.com/Swiftify-Corp/Swiftify/issues

Thanks for your incredible review!
While a 100% correct conversion nearly impossible to automate, we aim to save your time and efforts.

Since we have already invested more than 4 man-years of work in the converter, the reverse converter may be a huge project that would not pay for itself.
Xcode allows you to see Objective-C declarations generated in a mixed Objective-C + Swift project anyway.

Regarding implementing functions from Pods, could you please elaborate by replying to this email?

Pros: As primarily a swift developer. I really liked being able to see a side-by-side conversion of older obj-c code that I did not understand, with more familiar Swift code.

Since I used the free version, I mostly used it for small snippets of code, rather than larger file bases. I really liked that.

Cons: Overall it was good. But I wish there was a little better type checking and validation of the code. (pre and post conversion.)

But I also don't want it to not "convert" instantly.

Overall: The biggest problem that Swiftify solved for me was converting old archaic obj-c code to Swift. It really helped me learn both languages better.

Pros: Most of the time it works and you can get a nice head when starting to migrate your code, there is a decent business plan but specially useful is the customer support, the ceo itself helped once

Cons: Not very useful on complex tasks(have not tried the whole project migration tool), if you got a big method or using rare castings it can get confused easily, also when infering nullability, but anyway that is the most difficult part for the AI, maybe a two mode version could help there, a "nothing is null" check and a "all could be null", so the AI can get a clue, a strictier version and a more flexible one

Overall: Bringing legacy code to swift, modernizong my projects, sometimes for it to work better you need to refine the input, like dividing a big task into smaller ones, the converter works better there.

Cons: The use of force casting was my biggest annoyance, Force casting is kind of a big no-no for me and most linting standards.

Vendor Response

by Swiftify on July 15, 2019

Hey Joe,

Many thanks for your incredible review and suggestion!

Could you please suggest a use case (i.e. a swiftify.me code sample) where you find a force casting being generated, but inappropriate?

In the majority of cases our generated code uses optional access (`?`) operators, `if let` statements or optional / bridged casting (`as?`, `as?`) operators.
The exceptions include cases when we just don't have any other option, i.e. when unwrapping an optional in a method that returns a non-optional.

I would be glad to address your feedback as much as we actually can.
Feel free to follow-up with me here, and / or post any issue(s) at our GitHub Issue Tracker:

Pros: Simplicity of copying code right into on-screen console. Press of a button produces immediate translation of Objective-C to Swift code. Sometimes I'm looking for an easy way to translate Objective C code that I may find on the web that's not available in Swift - commonly on sites like Stack Overflow. I can get a Swift version using this tool.

Cons: At times perhaps the software does not accurately translate to correct Swift syntax. This may be due to something wrong in the Objective-C source code - so I'm unsure.
