Firebase runtime crash - FIRInstanceIDConfig

Question

I have added the Firebase SDK manually to my project. (Can't use cocoapods due to configuration issues.)

I use the following frameworks

FirebaseCore.framework        
FirebaseInstanceID.framework
Firebasemessageing.framework

In the AppDelegate I have imported the following:

#import "Firebase.h
#import <FirebaseInstanceID/FirebaseInstanceID.h>
#import <FirebaseMessaging/FirebaseMessaging.h>

If I make reference to

[FIRMessaging messaging].remoteMessageDelegate = self;

I get a runtime crash with the following error:

Error message in the console:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString fira_UTF32Length]:

However if I comment out that and make reference to this line of code

 [[FIRInstanceID instanceID] token]

I get this error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[FIRInstanceIDConfig setAllowGCMRegistrationWithoutAPNSToken:]: unrecognized selector sent to instance

I have added all the required frameworks I can think of, yet still getting this issue.
