I've got one old ipod touch 2g which can be upgraded just to 4.2.1. I also have xcode 4.5 which says:
Unsupported device Devices of type “iPod touch (2nd generation)” are not supported by this version of Xcode.
Is there any way I can develop for this poor old device on my current version of xcode? Thanks.
Go to your targets > summary > deployment target and set it to 4.3 or greater.
