I noted Eric Wings post on: "Command line instruments broken with pre-iOS 6 devices".

 

http://lists.apple.com/archives/xcode-users/2012/Sep/msg00187.html

 

I'm running XCode 4.5 and I too am experiencing similar problems:

 

3GS with iOS 6 -- works

3GS with iOS 5.1.1 - unable to start: Instruments Trace Error: Failed to start trace.

 

iPad2, iPhone4S with iOS 5.1.1 - works

iPhone 4 with iOS 4.3.3 - unable to start: Instruments Trace Error: Failed to start trace.

 

Note that this is invocation via commandline (instruments script).

 

When invoked through XCode UI (UIAutomation tool) it works on all configurations - so it seems this is a commandline issue only.

 

Did anyone manage to get closer to a solution (other than managing several installations on different machines/virtuals)?

 

 

Kind Regards,
