iOS Developer

I'm impressed with the code conversion for objective-C to Swift and Swift to Swift-UI. It saves a lot of time of many experienced developer who want to increase his/her productivity.

Principal

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.

iOS developer

I tried different systems, but no other systems is such successful. I also love to see storyboard to swift ui converter, but I did not test it yet.

Software Engineer

It’s useful and effective with relatively-quick support for new versions of Swift.

Student

Easy to use, I needed it for an exam. It saved me a lot of time and it converted the code very good.

Was really easy to use, just a converter which really works great by converting the code to the latest swift.

Operator

A fantastic product and great for beginners, highly recommend.

Admin

Missing a lot of features and very very bad translations.

Very easy to use, good conversion results...totally worth the money in time savings alone.

It's user-friendly, accurately translates code, and lets you customize the process. The helpful resources and responsive support team add to its appeal.

Really enjoy the simple UI and Xcode integration that allows you to easily convert between ObjC and Swift.

Swiftify is a useful programme for translating Objective-C code to Swift code. When we work on older projects, Swiftify comes in quite handy.

It's quite useless when it comes to complex code.

Product

Easy to use to convert code from Objective C to Swift.

iOS Engineer

The software is probably the best objc to swift converter on the market by a long shot. However the pricing model is not very friendly for individual developers.

And their pay as you go model is not very scalable if you have lots of objective-c code to convert. I suggest that there should be an individual subscription/licence available for single users.

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.

It doesn't always convert the code in a logical or readable way. Makes the code generated difficult to maintain.

Swiftify is a useful programme for translating Objective-C code to Swift code. When we work on older projects, Swiftify comes in quite handy. Also, I was able to utilise this to quickly convert some older projects I was working on into Swift by using it instead of just reading the documentation on my own, which helped me save a tonne of time. Swiftify is an excellent service overall; it assisted me in better understanding Objective-C when I was learning mobile programming and while I was working on some real-world projects.

Excellent tool with great functionalities for ObjC to Swift conversion

I appreciate your feedback.

The Offline Converter should be able to process files faster than the Cloud version, especially on Apple Silicon MacBooks.

If you face any slowdowns with specific files, feel free to file a ticket at https://github.com/Swiftify-Corp/Swiftify/issues or write to me personally at alex@swiftify.com

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.

Happy with the converter

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!

It was good to try, it's a nice project to make it work but if you want to have quality Swift code you have to write it yourself (or hire a professional)

It converts but the quality...

Thank you for your review and valuable input!

You are completely right - the task to convert Objective-C code to Swift is almost impossible to fully automate.
However, we have spent 5+ years on the development of this converter to save time by automating the routine part of the process.
This does not replace intellectual work required to further refactor the code to adhere to the Swift coding standards.

If you have any particular improvement suggestions, feel free to report them at https://github.com/Swiftify-Corp/Swiftify/issues

Alternatively, write back to me at alex(swiftify.com).

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. 

Nice software

I really appreciate your awesome feedback on the product.

Could you please suggest what issue(s) did you have with the customer support?
We are always willing to improve our product and services, so I'd definitely appreciate if you elaborate regarding this.

Thanks in advance for your time!

I didn't get a good chance to use it, as the free trial only allowed conversion of very small files. The small files that were converted, had been converted fairly well.

Again, if the pricing model was more fair for individuals I would have purchased a licence/subscription for myself.

Consider offering an individual subscription/licence for this product. Paying per file is not a good model in 2020.

Too expensive for individual users.

Thanks for your thorough feedback and suggestions!

We are still figuring out the best pricing model for the service, so I value your suggestions here.

I use when there is some part of code in objective c that needs only to be converted in swift. 

How to convert most function from objective c to swift

I really appreciate your awesome feedback on the product.

Regarding 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.

Feel free to follow me up with any questions or suggestions on this matter.

Thanks for your awesome review!

Regarding the UX improvements, could you suggest whatever do you feel most important?

Are you using the Xcode Extension, Advanced Project Converter or the website most of the time?

Thank you Swiftify!

It has helped a lot. Today I use it more for code fragments.

Saved me time and time is money.

Extremely useful converter

Simply the best objective c to swift converter

I really appreciate your feedback.

Regarding your report that some conversions do not correspond to the best option in the latest versions of Swift.
While we are working hard on generating the best possible output, it will be probably never possible for the automated converter to produce an idiomatic Swift code, which still requires a human being ;)

Anyway, we are working hard improvements such as generating "guard let" statements whenever possible.

You may post any distinct suggestions for review here:

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

Regular occasional user

Time saver

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!

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.

A great way to migrate single Objective-C documents

I really appreciate your awesome feedback on the product.

Could you please suggest what issue(s) did you have with the customer support? 
We are always willing to improve our product and services, so I'd definitely appreciate if you elaborate regarding this.

Any feedback is welcome!

My experience is good and useful,I use quite often and save my time also


Easy to use but....

After using many tools I fount this tool very useful. Now I don't need to code manually from Objective-c to swift because of this tool.

Most Advanced Tool

Nice Convertor

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.

Best way to convert the code from Obj C to Swift

I am a consultant.  I have been doing iPhone development since the beginning for many different companies. So I have written a lot of Objective C code.  A lot of legacy code needs to be converted and brought up to date.  This product has saved me a lot of time.

This product is a life saver

Has been great. My go to tool for conversion. Found it better than few others that I tried

My go to tool for Objective-C to Swift Convertion

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.

Transforming old projects

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.

Great for converting older projects

The easist way to have your code on Swift and Objective-C

Amazingly useful migration and conversion of old Object C code to Swift, with high accuracy.
