Can Objective-C code call Swift class extensions?

by

You can write a Swift extension and use it in Objective-C code. Tested with Xcode 6.1.1.

All you need to do is:

  • create your extension in Swift (@objc annotation needed since Swift 4.0.3)

  • #import "ProjectTarget-Swift.h" in your Objective-C class (where “ProjectTarget” represents the XCode target the Swift extension is associated with)

  • call the methods from the Swift extension
