Notice that If you wanna automate your IOS app it must be signed with the Developer Identity.It must contain Provisioning profile.“A valid iOS Development Distribution Certificate and Provisioning Profile are necessary to test on real device”
you may check here https://developer.apple.com/legacy/library/documentation/ToolsLanguages/Conceptual/YourFirstAppStoreSubmission/TestYourApponManyDevicesandiOSVersions/TestYourApponManyDevicesandiOSVersions.html
The above you had a message shows that it doesn’t contain dev. identity.Please ask your provider…!!!

@bhaskar

The app is code signed and it has been provisioned profile with the device as well… The app launches and crashes.
Ok assuming that dev id is incorrect,i tried in simulator and same is happening in simulator as well and below log is displayed( i have given only the main error,if required il give the entire log)

info: [debug] [INST STDERR] Instruments Trace Error : Target failed to run: Failed looking up pid of launched process

Note:
Iam trying on iOS8.1 devices and simulators.
Any limitations let me know
