![]() ![]() This finally felt like too much time to spend on a temporary setup, and I decided just to push toward a complete conversion without further attention to interoperability. This meant I'd have to convert all the subclasses of a superclass first, then convert the superclass, then go back and make adjustments to all the subclasses, and repeat that cycle as I work up the tree. The file can't be manually edited and sometimes took several clean/build cycles to get it to update.Ī Swift class can inherit from an Obj-C class, but an Obj-C class can't inherit from a Swift class. Xcode automatically generates a bridging header to expose Objc-C classes to Swift, but it makes assumptions about naming conventions that can create mismatches. I found myself doing a lot of temporary coding and documenting what could change once Obj-C was gone. Other types like enums have limited support in Obj-C - for example, Swift enums can't be used as a function parameter type - so I was limited in what new Swift features I could use. Even Objc-C int and Swift Int require casting. Some types like Array and NSMutableArray aren't automatically interchangable, so I had to insert a lot of extra type casting. And after converting about 30 classes, I found myself spending most of my time tweaking code for interoperability between Objective-C and Swift. I don't want the mental load of maintaining a hybrid of two different programming languages long-term. I have a project of similar size to the original poster (250 classes, 7 MB of source code). Here's a different perspective from the other answers. Step 10: You can set a shortcut (Key Binding) for any command via Xcode -> Preferences -> Key Bindings. Step 9: You can also use the Right-Click menu to convert code from most macOS text editor apps: Step 8: The new Finder extension allows you to convert files, folders and even ZIP archives with your projects using the Right-Click menu: ![]() Step 7: Run (or restart) Xcode and check the Editor -> Swiftify menu. Step 6: If there’s nothing in the Editor menu, open System Preferences -> Extensions and put a checkmark next to “Swiftify for Xcode”. Please, Sign In or Sign Up Free to get your own API key. Step 5: Run “Swiftify for Xcode” from your Applications folder and enter the following API key: Under the section labeled "Allow applications downloaded from," select "Mac App Store and identified developers". Step 4: If the app is blocked from running, go to the Apple menu > System Preferences. Step 3: Download and install Swiftify for Xcode. Step 2: Sign or Sign Up to site to download the app. Step 1: Make sure you have latest version of Xcode (Recommended Xcode 11 & newer). You can use "Swift + Objective-C" as of now to make your app running smoothly and also giving updates regularly rather than waiting for the months to convert it completely.You may end-up having clean code under proper structure.You may find some unusual code or libraries lying around.Andreas Oetjen Suggestion: You might start by separating the class hierarchy, and convert one "subtree" after the other.Besides, you can also build modules from scratch in the form of smaller projects and then just drag and drop in Objective-C project.Once you are done with smaller ones, slowly start picking up big modules also you may find open source Swift libraries which are in Objective-C in your project.Reference: How can I import Swift code to Objective-C? From your project, first of all start picking up smaller modules which don't affect app in any way and see that the "Swift" file works well with Objective-C (Your old code).Rather than start converting complete project, adapt modular way.Pick the latest version of Swift (i.e.So what I suggest you to go via following way: The biggest problem is that Swift is still evolving and probably next year we might see "Swift 5.0". Your approach of converting Objective-C to Swift is wrong! Apple also took time to adopt Swift completely in their frameworks and the news is in 2018, 85% of the frameworks are converted to Swift, so the point is they has also taken nearly 3 years to get it done! ![]()
