After I integrated the AdMob SDK, I kept getting this error when trying to build it on a real device. The weird thing is, when it is built on the iOS simulator, everything works correctly.
Apple Mach-O Linker Error
ld: framework not found Metal for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I'm using xCode 5.1 and testing on an iPhone 5S running on iOS 7. Please help!
