Why am I seeing “An error occurred while trying to run the script.” in the UI Automation instrument?

Question

When I try to run a UI Automation script on iOS 5 devices I am getting the following error:

\"An error occurred while trying to run the script.\"

Answer 1

On devices you should explicity allow to run UI Automation scripts.

• Go to Settings -> Developer
• Switch Enable UI Automation to on

After turning the option on, the error went away and everything worked as expected.
