I'm trying to upgrade from Google Sign-In SDK 1.0.0 to 2.0.1 and ran into some conflicting constraints when trying to position an instance of the GIDSignInButton.
It seems like GIDSignInButton may define its own dynamic constrains which conflict with the ones I set in Interface Builder. I'm not able to verify this since the SDK is closed source.
The constraint warning can actually be reproduced with Google's own sample code on https://github.com/googlesamples/google-services/tree/81c831d85a67157746009fa2df81a683f860d21e/ios/signin.
Is there a work around to position this button or is this just a bug in SDK 2.0.1?
Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x7f9e0064b650 V:[UIView:0x7f9e0064b360(198)]>",
"<NSLayoutConstraint:0x7f9e0064b830 UIView:0x7f9e0064b360.centerY == GIDSignInButton.centerY (Names: GIDSignInButton:0x7f9e0046f000 )>",

)
Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Google has fixed this bug in Google Sign-In SDK 2.1.0 (released on 6/17/2015).
