I just downloaded the GNSDK for iOS (gn-mobile-ios-1.2.1.4576) and cannot get the demo app to run in the emulator.
Here's the error I am getting:
GracenoteMusicId[49126:28681347] Unknown class _TtC16GracenoteMusicId21GnViewControllerSwift in Interface Builder file.
I am running Xcode 8.2.1 and trying to run on an emulator of iPhone 7 Plus.
I upgraded the project to Xcode 8, and that compiled without issue, but I get this error both before and upgrading the project to Xcode 8.
Either a storyboard or nib has an object in it with a custom class set to a class in the Gracenote library, however that library is not being linked into the final binary. You need to make sure the library is being linked correctly.
