1) I cant use my iPad with iOS 5.1.1 in XCode 7.0 (7A220). In "Devices" window:
"Unsupported device model: "iPad is of a model that is not supported by this version of Xcode..."
2) Is impossible to upload iOS 5 simulator to Xcode 7; the oldest available is iOS 6.
What can I do to work this iPad withXcode 7?
XCode hasn't supported iOS 5 simulation for longer than that. Check my post on the thread Install ios 5 simulator to xcode 5.1? to see how I ran iOS 5 simulators on a mac with recent versions of XCode loaded.
