Firebase Phone Authentication broken after pod update - ios

Question

In my setPhoneNumberVerificationID() function, I am hitting this error:
'Error Domain=FIRAuthErrorDomain Code=17053 "Remote notification and background fetching need to be set up for the app. If app delegate swizzling is disabled, the APNs device token received by UIApplicationDelegate needs to be forwarded to FIRAuth's APNSToken property." UserInfo={NSLocalizedDescription=Remote notification and background fetching need to be set up for the app. If app delegate swizzling is disabled, the APNs device token received by UIApplicationDelegate needs to be forwarded to FIRAuth's APNSToken property., error_name=ERROR_MISSING_APP_TOKEN}'
My didReceiveRemoteNotification function looks like:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
if Auth.auth().canHandleNotification(userInfo) {
completionHandler(.noData)
return
}
guard let aps = userInfo["aps"] as? [String: AnyObject] else {
completionHandler(.failed)
return
}
print("got something, aka the \(aps)")
}
This is the setPhoneNumberVerificationID function:
func setPhoneNumberVerificationID(phoneNumber: String) {
PhoneAuthProvider.provider().verifyPhoneNumber(phoneNumber) { (verificationID, error) in
if let error = error {
print(error) //hitting this error here
return
}
guard verificationID != nil else { return }
print("error is: \(error) and verificationID is \(verificationID)")
//do stuff with verificationID
}
}
As you can see below, my remote notification and background fetching is on.

I had to very slightly change the .verifyPhoneNumber() arguments, because it used to take a 'uiDelegate: nil' parameter as well...how do I fix this???
