Answer 1

check your Other Linker Flags probably you have $(inherited) with other flag to GoogleMaps -framework "GoogleMaps". I recommend set just $(inherited)

Answer 2

I had the same problem and I have fixed it by removing -all_load from Other Linker Flags and I let CocoaPods to set my flags.

Check your project settings for this flag.

Answer 3

I've noticed same problem with Xcode 6.2. No problem at all with Xcode 6.3.2 Workaround would be to use

pod 'GoogleMaps', '1.9.2'

which working fine for me (with Xcode 6.2)

Answer 4

I had similar problem where there some other entries along with -ObjC in Other Linker Flags. Removing all other values except -ObjC solved my problem.
