So, create a vanilla project, build & run... App does not appear. Open console:
"1/10/12 6:32:29.967 PM taskgated: killed com.myapp.TEST[pid 28092] because its use of the com.apple.developer.ubiquity-container-identifiers entitlement is not allowed"
Pretty much the same question as here Turning Entitlements on in Xcode Prevents Bare Bones App From Launching
And here. Mac application crashes (killed due to entitlements) regardless of whether entitlements are enabled
I am not using iCloud. In fact I haven't even changed the default project. Any solutions or ideas? Thanks to anyone who has overcome this.
