swift file to your project, and name it MySwiftObject.swift. Using Swift Classes in Objective-C Step 1: Create New Swift ClassĪdd a. Starting with Xcode 4.2, the Clang compiler became the default compiler, Starting with Xcode 5.0, Clang was the only compiler provided. There is no need to import explicitly that's what the bridging header is for. In Xcode 3.2 and later, it included the Clang C/C++/Objective-C compiler, with newly-written front ends and a code generator based on LLVM, and the Clang static analyzer. Print(instanceOfCustomObject.someProperty) InstanceOfCustomObject.someProperty = "Hello World" In SomeSwiftFile.swift: var instanceOfCustomObject = CustomObject() In YourProject-Bridging-Header.h: #import "CustomObject.h" (void) someMethod 5: Add Class to Bridging-Header (void) CustomObject.m #import CustomObject
In CustomObject.h #import CustomObject : (strong, nonatomic) id someProperty It might look like this: $(SRCROOT)/Folder/Folder/-Bridging-Header.hĪdd another. $(SRCROOT) can be thought of as the directory that contains your.
It's best practice to link your project using the $(SRCROOT) macro so that if you move your project, or work on it with others using a remote repository, it will still work. h file named as mentioned above, then make sure you link its path in your target's project settings like so:
In some situations, particularly when working with Objective-C frameworks, you don't add an Objective-C class explicitly and Xcode can't find the linker. (For some cases, I had to add an explicit #import -Bridging-Header.h. If you have an existing class that you'd like to use, perform Step 2 and then skip to Step 5.
