When i am connecting my 3gs(iOS 5.0.1) device to Instruments i am getting this error message
" Failed to start Instruments daemon for 'iOS' on iPhone 3GS (v5.0.1)' (The service is invalid.)
Please reconnect the device."
This message appears on instruments, when ever i re-connect the device. How can i do performance testing with this device.
Thanks.
I received this error message while trying to run instruments on with iPhone4s and 3GS. To resolve that issue I open the Xcode than select select the windows>organizer select the device and clear the Consol and device logs. After above steps instruments have detected the device.
