OK, so I recently enrolled in the iOS dev program. After completing my purchase, I needed to get certificates, provisioning profiles, etc. I selected use this device for developing in the xcode organiser window, then right clicked on the device, add device to provisioning profile. All is going well. I open up my xcode project with my app, and click build and run (Debug, device) Then, an error pops up. The executable was signed with invalid entitlements. The entitlements specified in your application’s Code Signing Entitlements file do not match those specified in your provisioning profile. (0xE8008016). ADDITIONAL DETAILS FROM ORGANIZER: Device: Devices/iPhone 4 Device PP: Team Provisioning Profile * Development/developer profile: iPhone developer: Christopher Healy Provisioning profiles: Team provisioning profile * /provisioning profiles: Team Provisioning Profile * Devices included: iPhone 4 Any advice would be appreciated. Thanks in advance for your help, BY THE WAY: I will be continuously viewing this thread. Feel free to ask any questions, or suggest things. I will try them and respond with if/how they work.
