I JUST finished my first app in Xcode 4.3.2 and want to test it on my iPhone which I (unfortunately) updated to OS 6 without thinking about the fact that I’d probably have to be using Xcode 4.5. So I downloaded the the 4.5 and tried to open my project in it, and I get the following error message all of a sudden:
apple mach-o Linker Error
Linker command failed with exit code 1 (use -v to see invocation)
My app was running JUST FINE in 4.3.2. I did not touch anything, I only opened the app in the new version and now I get a build failed with the above error. Can anyone help!? this is so frustrating! My app has Facebook integrated into it, so maybe that is related? I have no idea… any help would be greatly appreciated.
Hmm maybe you could try to see if the Facebook framework is added..
