Google Sign In not working on iOS 10 Beta 7 with Xcode 8 beta 6

I have an app in the app store which worked perfectly fine till first few betas of iOS 10 (i am not exactly sure which one). It also works perfectly fine on iOS 9.3.

However I am not testing on iOS 10 beta 7 and the google sign in is completely broken. I am using the latest version of


Here's my code:

[GIDSignIn sharedInstance].clientID = [[ParseFetcher sharedInstance] getRandomParseK];
[GIDSignIn sharedInstance].delegate = sharedInstance;
[GIDSignIn sharedInstance].uiDelegate=sharedInstance;
[GIDSignIn sharedInstance].scopes = [NSArray arrayWithObjects:@"",@"", nil];
[[GIDSignIn sharedInstance] signIn];

This is how it looks like on device:

It just stays stuck like this.

If I click the refresh button at top, it tries to refresh and gets stuck here forever.

Clicking on the done button sends me back to my app.

There are no errors logged in the console.

However, when I run the same app on iOS 10 simulator, the
safari view controller
doesn't even open. Nothing happens at all. But the console logs this long verbose stuff out of which the following seems like the most "useful" stuff but I have no clue what's wrong:

NOTE: iOS 9.3 works perfectly. Also happens on all devices - tested on iPhone 6s and iPhone 5s.

I am not sure if this is what other people are facing but I solved it by adding a [self.view layoutIfNeeded]. I know this is weird but this is what worked for me, I am myself not sure why.

I was using a custom view container inside which I was showing the Google's sign in view controller as a child. So before adding the custom view controller to the container, i had to do [self.view layoutIfNeeded] as else the view layout hadn't been set yet, so google's sdk probably uses the width/height somewhere inside.

I am not sure if this is the right solution but it seems to have fixed my issue.
