To import Swift code in Objective-C first of all you need to have an Objective-C bridging header. This is recommended by Apple and you can read more details about it on this documentation page. Change enum to NS_ENUM, this will improve code competition in Xcode and will specify the type and size of your enums.When creating properties you get by default getter and setter methods automatically, you will also have access to property attributes such as: weak, assign, retain etc. Use properties instead of instance variables where applicable.Instead of id as a return type your class uses instancetype, which will improve type safety.Let’s start! Step 1 – Modernize your Objective-C codeįirst of all make sure that every new file you create, if possible, is in Swift, if not, modernize your Objective-C code.

I faced a lot of challenges that I will describe in order to help you out if you decide to start with this project (and also to have a reference for myself if I have to do it again). I thought that the process would be fairly straightforward, but I was wrong. Why do you want to do it?įor us it was easy, we wanted to have a framework that will be fully compatible with Swift, use new patterns and features found only in Swift, be easier to read, and maintain and have a modern codebase for new developers joining the team.

Before you start converting Objective-C code to Swift first you will have to ask yourself if is it worth it.
