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."

The same script is running perfectly in the simulator or on an iOS 4.3.3 device.

How can I solve this problem?

Answer 1

I would try closing xcode and starting the automation script without xcode running. I had an issue where the process was attached to xcode, when I attempted to run from instruments, xcode got stuck on a breakpoint/crash and I couldn't proceed.

The solution I'm proposing is run Instruments independent of xcode.

Answer 2

This should fix this issue:

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Answer 3

Might be you are having more than one Xcode in your machine either delete others or Just follow these steps

1 Open Xcode and go to its preferences. 2 Then open Location tab 3 In command line tools select the Xcode version that you are using . it might be possible that this entry is wrong

Answer 4

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.
