XCode: Could Not Support Development

Today  when I started my work on an iPhone project, my XCode failed to mount my iPhone. The XCode organizer was showing an orange dot next to it instead of the usual green one. Organizer complained “Could Not Support Development”. I tried restarting my XCode, launched iTunes but in vain. iTunes was able to mount my iPhone but XCode simply failed and I was not able to test my app’s on my phone. Finally I restarted my iPhone and tried again. Bingooo..! it started working again. My iPhone was running the latest iPhone OS 3.0 GM developers build. See left for the screenshot of the error message that I got.

Error Starting Executable

Quite a few times in our iPhone application development cycle we would encounter XCode error “Error Starting Executable – No provisioned iPhone OS device is connected.” even when we know the device is connected to the machine.   This error occurs when the connected device is not configured in the XCode->Organizer. Organizer would fail to mount the device as the version of XCode installed on the developer machine may not support the version of iPhone OS installed on the device.

If you select the device in the Organizer, then XCode would list you the supported iPhone OS versions as well as the OS Version of the device. (An organe dot aganist the device in Organizer indicates it has not been mounted properly.)
