How to fix Failed to fetch default token error?

Question

I am getting this error after installing in iphone.

Solution 1

Using Xcode8, the fix was to simply enable Keychain Sharing in Capabilities

Open the app.xcworkspace file, select Target > Capabilities > Enable 'Keychain sharing'

Solution 2

Possible reasons for this issue:

1. Device date was not set to the current date.
2. Bundle ID is not same that one you set in GoogleService-Info.
3. .p12 certificate uploaded on Firebase Console is not correct.

Solution 3

Make sure that:

• Bundle ID is the same that one you set in GoogleService-Info
• Code signing params (Target => Build Settings => Code signing) are corrects and match with p12 cert file you've set in Firebase.

Also, you have to follow those tutos:

• Notification: https://firebase.google.com/docs/notifications/ios/console-audience
• Configuration: https://firebase.google.com/docs/ios/setup

And don't forget to ask permission to user simply to add that in your app (In AppDelegate file, or in other ViewController for example):

let notificationTypes: UIUserNotificationType = [UIUserNotificationType.Alert, UIUserNotificationType.Badge, UIUserNotificationType.Sound]
let pushNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
application.registerUserNotificationSettings(pushNotificationSettings)
application.registerForRemoteNotifications()

While it's always good to link back to another SO answer, please always include the full answer in the one you also provide the link. -1

Best not to add that "in AppDelegate file for example", as no one will accept the push notifications permission on the first app start.

"1. Device date was not set to the current date." a very important and interesting point. You saved me some time! Thanks! Anyhow, does anyone know why it doesn't work if the device date is not set to the current date?

[Rachit Rawat]

If the device date is not correct, then Firebase can't figure out when to fetch the device token next, as you know Firebase keep on trying to fetch tokens at a regular interval.

Why does this capability is required?

[Krutarth Patel]

@RachitRawat device date means.can you explain in detail?

[Rachit Rawat]

Device date means date on your iPhone. You can change it via Settings. @KrutarthPatel

@RachitRawat thanks bro.i am getting red mark add push notification entiliment to app id.

[Rachit Rawat]

Anytime bro. Just upvote the answer instead of thanking me, since it took me years to figure out the solution for this issue. @KrutarthPatel

[Krutarth Patel]

@RachitRawat red mark error sometime come and go.can you guide?

[Rachit Rawat]

@KrutarthPatel Can you be more specific? What's the error line it's showing?

[Tim]

This was a fix when you have no Entitlements file, because the APNS Capability alone wouldn't generate an Entitlements file, causing the app to not register with APNS. I believe this has since been fixed, but regardless, if you have a manual Entitlements file, or other capabilities that generate one, this will not change anything.

You saved my day really !

Thumbs up for Device date!

P12 Certificate for me was for development rather than distribution, thanks.
