在Swift Framework中导入和使用Google SignIn iOS SDK

Question

I need to import Google/SignIn SDK in a swift framework MySDK which is used in MyApp and I'm not quite sure how to do that. I use CocoaPods as a dependency manager.

Here is some background:

Main app

If I wanted to use Google/SignIn in the main MyApp , I would need to include the following line in the MyApp-Bridging-Header.h :

#import <Google/SignIn.h>

That would allow me to import Google in any swift file and use it, no problem.

Dynamic framework

Dynamic frameworks don't have bridging headers, so I tried to put in the umbrella header MySDK.h . However, this produces the following error:

Include of non-modular header inside framework module 'MySDK'

Although not importing <Google/SignIn.h> allows MySDK to build successfully and use Google SDK throughout the framework, when I try to import MySDK in MyApp , I get the following error on the import MySDK line:

MyApp/ViewController.swift:10:8: Missing required module 'Google'

What's interesting is that I have this problem only with Google SDK. All the other dependencies, like Facebook LoginKit work without any issues.

Answer 1

I was facing the same issue. This may be a trick but it worked for me i explicitly installed Google/SignIn pod in my main project too, doing this provided the main project the dependency it was unable to locate and thus I was able to use my dynamic framework.
