I use firebase as part of a project that I am working on on iOS, and I just stumbled upon the following binding error when I try to compile my code using the iPhone 6 or 7 simulator for testing.
Undefined symbols for architecture x86_64:

I am using Xcode 8.2.1, swift 3.0, and I also have the following Pod file in my project
pod 'Braintree'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Core'
pod 'Firebase/Storage'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'GeoFire', :git=>'https://github.com/firebase/geofire-objc.git'
pod 'ObjectMapper', '~> 2.2'
I did a module update in case something is out of date but no luck. The code compiles and works fine when I use the iPhone 4 or 5 simulator.
Edit:
I set Build Active architecture to No, in the allowed architectures I have listed arm64, armv7, armv7s, and now Objectmapper fails, although it is import ObjectMapperdeclared in the file
Use of undeclared type 'Mappable'
Any help would be greatly appreciated! Thank you in advance.
George.
