Crash with FirebaseAuth.sendSignInLinkToEmail on iOS

[treitter]

Hello, I'm getting the following crash on iOS:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[FIRActionCodeSettings setDynamicLinkDomain:]: unrecognized selector sent to instance 0x600000012250'

It seems to be caused by calling setDynamicLinkDomain in firebase-ios-sdk which doesn't exist in the version my app depends upon (12.4.0 but also if I upgrade to 12.7.0). Dynamic domains are deprecated and about to go away entirely so losing access to this upstream API wouldn't be a loss at all.

I can work around this locally by swizzling setDynamicLinkDomain to a no-op but it would be much cleaner to not have to do that and it's not a best practice.

I think this could be fixed by upgrading the firebase-cocoapods dependency to a newer version. I'm not sure exactly which one but it seems to be at least one major version behind.
