Specifically when I need to create a new Swift class and I need to use already existing code on Objective C, I use to convert it first with Swiftify, so I can save some time in the process. The Swift Language for that is going to need to change to Swift 5. Swiftify provides multiple options for converting Objective-C to Swift, but the new Advanced Project Converter (included in Swiftify for Xcode) is the easies. It is quite easy to use, just need to implement it in XCode and then just select the code and the option 'Convert selection to Swift'. Download softwareName and enjoy it on your iPhone, iPad and iPod touch. You're gong to have to do the same thing to Audio Mixer DemoTests because it's also initially set to Unspecified. Read reviews, compare customer ratings, see screenshots and learn more about softwareName. 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. The result should say Swift Language Version - Unspecified:Ĩ- Just click Unspecified and change it to Swift 5ĩ- In the 8th pic above, on the left side the TARGETS section is on the first target that says Audio Mixer Demo. Overall: 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 the blue triangle iconģ- Find the yellow triangle warning for project, click each one, then when the alert appears validate changes when requested.Ĥ- You should then get a compilation error, with Swift version undefined:ĥ- In the Project Navigator (left pane), select the blue project icon:Ħ- Select Build Settings and make sure that underneath of it, it's set to All and Combinedħ- In the right search bar enter Swift Language. Also, uninstall any previous version (s) of Swiftify for Xcode or Swiftify Offline Converter. Consider upgrading to the latest version of Xcode before proceeding. Apple designed the Swift runtime to work extremely well with those libraries. Offline Converter Installing Swiftify for Xcode Make sure that you have Xcode 14 (or Xcode 13) running on macOS Ventura (or Monterey). The Foundation and UIKit frameworks are still written in Objective-C. Xcode offers great interoperability between Objective-C and Swift. I followed this Apple Forums answer which works fine.ġ- When you open project, you get this alert:Ģ- Select OK and open Issues Navigator (press command button + 5). You won’t be able to convert your third-party Objective-C libraries to Swift, and there’s nothing wrong with that. As there are no changes to the existing format, there isn't a syntax converter for converting between Swift 5.x versions in Xcode.I just ran into this problem with an old Cocoapod file that is written in Swift 3 but my Xcode supports Swift 5. Since Swift 5.0 achieved ABI Stability, all new changes to the language are additive. You won’t be able to convert your third-party Objective-C libraries to Swift, and there’s nothing wrong with that. It can be done using Xcode, Go to Xcode->Preferences. It’s fairly easy to Switch to the new toolchain when we downloaded it successfully. Note: Xcode 14.3.1 converts your Swift code to Swift 5.8.1, even though the Swift Language Version dropdown under Build Settings shows Swift 5 ( learn more). It’s time to use the newly downloaded Swift toolchain. To get an earlier version of Xcode, you can use your Apple Developer Account to download it from the Apple Developer Portal:įor more information on migrating to Swift 5, check Swift’s official blog, where you can also find migration guides for earlier versions of Swift. To migrate to a newer version from Xcode, choose Edit -> Convert -> To Current Swift Syntax from the Xcode menu.ĭepending on your source code's Swift version, you might need a different Xcode version for the conversion. Swiftify does not include a converter between different Swift versions because such a converter exists in Xcode. How to Use Appcode and Swiftify to Accelerate Your App Conversion to Swift Swiftify offers various methods of converting your Objective-C code to Swift.
