technology and computing programming languagesHow do you create a bridging header in Objective C?
Beside this, how do I add a bridging header in Xcode?
How to create a Swift Bridging Header Manually
- Add a new file to Xcode (File > New > File), then select “Source” and click “Header File“.
- Name your file “YourProjectName-Bridging-Header.
- Create the file.
- Navigate to your project build settings and find the “Swift Compiler – Code Generation” section.
- Step 1: Add Objective-C Implementation — .m.
- Step 2: Add Bridging Header.
- Step 3: Add Objective-C Header — .h.
- Step 4: Build your Objective-C Class.
- Step 5: Add Class to Bridging-Header.
- Step 6: Use your Object.
- Step 1: Create New Swift Class.
- Step 2: Import Swift Files to Objective-C Class.
Consequently, what is a bridging header?
Its correct to say, Bridging header allows user to use Objective-C classes/files in their swift code in same project. A Swift bridging header allows you to communicate with your old Objective-C classes from your Swift classes.
Using Objective-C code in Swift files In the so-called bridging-header file you can import Objective-C files. Xcode translates then all signatures to Swift, so that it feels like you are calling real Swift functions. The easiest way to create the bridging-header file is by creating a new Objective-C class.
