If you’re
- an iPhone developer on the Mac, and
- you’ve recently (inadvertently?) upgraded your iPhone or iPod Touch (using iTunes) to the latest iPhone OS 2.2.1
you may find yourself unable to “Build and Go” apps from Xcode. Fortunately, Apple has released the latest iPhone SDK which when installed should resolve this issue.
If the Organizer window in Xcode still lists your iPhone or iPod Touch device with a yellow status and Xcode complains of “…go download the disk image…”, chances are your developer disk image was not installed properly. I’d usually advise your launch Terminal.app and perform the requisite
sudo /Library/uninstall-devtools –mode=all
before reinstalling Xcode…but if you’re adventurous, you could attempt to
- launch the latest iPhone OS 2.2.1 SDK,
- double-click to open the Packages folder,
- double-click on DeveloperDiskImage.pkg,
- follow the installer’s instructions and don’t forget to specify the location (usually /Developers).
Your iPhone or iPod Touch should now be listed sans problem under Devices in your Xcode’s Organizer window.
G’luck and happy coding!
