Answer 1

Problem seems to be with

• FirebaseInstanceID Version less than 1.0.9

• FirebaseInstanceID Version between 2.0.1 - 2.0.3

Set your pod file as below :

For Swift 2.3 and Xcode 8 : (FirebaseInstanceID v1.1.0 gets installed)

pod 'Firebase/Core', '3.8.0'
pod 'Firebase/Messaging'

For Swift 3 and Xcode 9 :

pod 'Firebase/Core'
pod 'Firebase/Messaging'
pod 'FirebaseInstanceID', "2.0.0

I didn't want to upgrade to FirebaseInstanceID 2.0.0 to fix the issue as I wanted use Swift 2.3 only
