How to develop for iPod Touch 2G with Xcode 4Published 2011-05-02
After I upgraded to Xcode 4, I got the following message when I tried to deploy to my iPod Touch 2G:
Xcode cannot run using the selected device. No provisioned iOS devices are available. Connect an iOS device or choose an iOS simulator as the destination.
Apparently my project had iOS 4.3 as a deployment target, but my device had iOS 4.2.1. I tried to upgrade the device's OS with iTunes, but it clicking Check for Update gave the following message:
This version of the iPod software (4.2.1) is the current version.
Apparently 4.2.1 is the last supported version for the iPod Touch 2G (search "for highest supported operating system" on the iPod Touch wikipedia article).
At first I thought I needed to download the whole 4.2.1 SDK + Xcode installation, but it didn't make sense why Apple would make this necessary. Instead it turns all I needed to do was click on Project Settings, Build Settings, and in the Deployment section set the iOS Deployment Target to iOS 4.2.
