Updated to Xcode 8 and Firebase plugin 3.6.3, now unable to launch app

Platform: iOS
TNS: 2.3.0
Firebase version: 3.6.3

After updating to Xcode 8 and the plugin to 3.6.3 (which supposedly were going to fix compatibility issues with Xcode 8), I am now unable to launch my app. The log prints the following:

Been trying to google this error but no one has ever fixed it with an explanation to why it happened.

Is this the iOS Simulator?

[NordlingDev]

@EddyVerbruggen - Yes, iOS simulator. However, I just noticed that the reason my app couldn't start was due to another issue. But the simulator (iOS 10) also brings me this alert when logging in to a Firebase account, which prevents a user to proceed:

EDIT - Device and simulators I've checked are:

Simulator, iPhone 7 (iOS 10) - Fails
Simulator, iPhone 6s (iOS 10) - Fails
Simulator, iPhone 6s (iOS 9.3) - Succeeds
Device, iPhone 6 (iOS 10) - Succeeds

So it is definitely an iOS 10 bug in the simulator (still works on my physical iOS 10 device). For now I can still use the 9.3 simulator. Just letting you know that the bug is there though.

EDIT 2 - It appears that this is a Firebase issue in itself, not your plugin. Found this blog post at Firebase mentioning the error given: https://firebase.googleblog.com/2016/08/ios-10-xcode-8-and-swift-3.html

I found a way to get rid of this issue as I had to fix it for my Cordova Google Sign-In plugin as well (and I think the Cordova Facebook plugin suffer the same issue):

Open the Xcode project via the platforms/ios/appname.xcworkspace/ file - then select your app's target, capabilities, enable 'Keychain sharing'.

Please let me know if this solves the issue for you as well.

I've automated this for the Cordova plugin, so I may be able to do the same for this one.

[NordlingDev]

@EddyVerbruggen - Yes, that does fix the issue. However I am not sure that's a good idea to implement because I read somewhere (might've been in that article) that it could lead to security risks.

[EddyVerbruggen]

Good. I'll add it to the readme for now.

I'm afraid it's the only way to fix this.. that security risk is on Apple.

[EddyVerbruggen]

Automated this step in 3.8.0.

Having the same issue (everything was working fine till I updated TNS to 3.1.1) and I started getting this error (I've changed the Keychain Sharing as well, without any success).

Any ideas? Using version 4.0.3 of the plugin.

I have the same issue after updated to TNS to 3.1.+

[EddyVerbruggen]

Can you share the error you see?

[EddyVerbruggen]

Yeah that's unrelated to this issue. I'm not sure what to do yet. Please use a real device to test on in the meanwhile.
