I have upgraded to xcode 5.0 and Instruments 5.0. Problem: Can not make a new recording / new script. It worked before upgrade.
How to recreate problem: - Make a new instance with the template "Automation" - Go to "script" - Choose "Add", then "Create". A code line "var target = UIATarget.localTarget();" is created as expected in the script pane. - click the red record button at the bottom of the script pane Simulator opens as expected (iPhone Regina (4-inch 64-bit)/iOS 7.0.3) Problem: in the script pane it says "Starting capture" and this does not stop and recording does not work. In the "Editor log" it says: "An error occurred while trying to run the script".
I have restarted Instruments, xCode and the computer a few times.
