GoogleClientManager.Initialize() throws null ref whatever I do on IOS

[KshitijAgrawal]

Describe the bug
in AppDeletgate, I have read everything on internet and tried fixing all the things mentioned everywhere, but GoogleClientManager.Initialize() throws null ref. I am building on device and the same app works on android. I have the googleservice-info.plist as bundle resource. If I try to load the plist in the appdelegate itself, it works and I can load it with the name as you are doing.
I have a valid wildcard provision profile and I use it to deploy the code on my device.
Is it possible to get some logging in the library with Debug.WriteLine() ?

It seems like maybe the SignIn.Sharedinstance is null.

So it seems like it only works if you compile on a mac. If you do Hot reload through visual studio the Sharedinstance will always be null.
