GIDAuthentication is missing fetcherAuthorizer method

[Johan Nordberg]

I've updated a project that uses Firebase, GoogleSignIn and GoogleApiClientForRest/Youtube to the latest version and now the fetchAuthorizer method is missing. My code used to look like this and worked well:

let user = GIDSignIn.sharedInstance().currentUser

let auth = user!.authentication

let authorizer = auth!.fetcherAuthorizer()

But now I get an error on the last line where I try to access fetcherAuthorizer. "GIDAuthentication has no member fetchAuthorizer"

My podfile look like this:

platform :ios, "9.0"

use_frameworks!

target "xxxx" do
  pod 'GoogleSignIn'
  pod 'GoogleAPIClientForREST/YouTube'
  pod 'Firebase/Core', '~> 4'
  pod 'Firebase/Messaging', '~> 4'
end

I have imported GTLRYoutube.h in my bridging header:

#import <GoogleAPIClientForRest/GTLRYouTube.h>

Can someone help me?

The issue is the use of a bridging header.  Sadly, bridging headers will strip all properties, methods, etc. that reference an "incomplete" type.  Incomplete is caused simply be things being forward declared (@class Foo, @protocol DoSomething).  To have the properties exposed, you have to manually import the header that define the forward declared types:

Try adding:

  #import <GTMSessionFetcher/GTMSessionFetcher.h>

  #import <GTMSessionFetcher/GTMSessionFetcherService.h>

That should fix the problem.  When you hit this sorta issue in ObjC, it can kick out an error about the type of the property being incomplete, but with a bridging header it just drops them leaving it in this confusing state when you try to access them.
