Bridging Objective-C to Swift
Understand how to expose Objective-C classes and methods to Swift using the bridging header.
Bridging Obj-C to Swift
Welcome! In modern iOS development, you'll often encounter projects that mix Swift and Objective-C. This is especially true for legacy apps or when integrating older libraries.
This lesson teaches you how to make your existing Objective-C code accessible and usable within a Swift project, a process known as bridging.
The Bridging Header
The key to using Objective-C code in Swift is the bridging header. This is a special Objective-C header file that tells the Swift compiler which Objective-C classes, categories, and protocols it should expose to your Swift code.
Think of it as a translator's dictionary for your project.
