  • 772

I am making an app in swift, but I had to use a library that is only in objective-c, so I had to create a file .hand another file.m

The problem is that from the file .mI have to call a function AppDelegatethat is in swiftbut I don't know how to call it, because it tells me that AppDelegateit is not declared.

How can I do it??

  1. Indeed I have not done the test, but according to the documentation it is possible that both codes coexist in the same project.

    I leave you the Apple documentation: https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html

    Greetings.

    There is a header that is generated automatically when you compile.

    #import "ModuleName-Swift.h"

    ModuleName depends on the name of your project. If your project is called TestProyect, then it will be TestProyect-Swift.h
