Apple Mach-O Linker Error Code 1

Question

Linker command failed with exit code 1 is in red. How do I fix this? My other question is... I already submitted this app to Xcode and it was working fine the other day. If I cannot correct this.. would I be able to download the one I sent to Apple?

Thank you

ld: framework not found AVKit for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

i386 Mac compiler expects AVKit framework suitable for it. But you might have included only device framework. Either including simulator (i386) framework or Building application for Device would help you.
