Common Xcode erros & their remedies

Here are a few of the errors that I've come across, their descriptions and fixes;

This error comes up when you try to pass an invalid method or value the an object

The executable was signed with invalid entitlements.

This classic error with the following text;
The entitlements specified in your application’s Code Signing Entitlements file do not match those specified in your provisioning profile.
you need to make sure they are the same.
  • Goto Xcode-Window-Organizer-Devices and then goto the connected device's Provisioning Profiles tab.
  • Note the name of the currently valid profile;
  • In Xcode goto program-target-Project-Build Settings-Code Signing and copy the appropriate profile name into the Code Signing Identity field and also in it's children
Recompile & Off You Go!
