I have done quite a bit of research on this issue and have been running up against a wall all day. I know that there are many posts on this but so far none have been helpful. I am running the latest XCode 4.2 on Lion. I have tried deleting, cleaning and replacing the entitlements file. I have reloaded all of my provisioning profiles and verified that the build settings in both the project and the target are correct.
I can run in debug mode on the device but if I archive it as an ad-hoc and try to install the .ipa on an iPad I get an error that says "The executable was signed with invalid entitlements".
In the latest xCode there is no "Get-task-allow" or "can be debugged" check box on the entitlements file that I can see.
In the past when I have encountered this problem it was a simple fix but now it seems like nothing is working. What am I missing?
On XCode 4 entitlements are no longer required for ad-hoc builds. Try deleting your entitlements file completely and seeing if that helps. You can refer to this technical note for more information.
