Is it possible to debug my application on iOS 7 from Xcode 7?
From what I can tell, Xcode 7 just ignores any connected devices with iOS 7 installed. Is it just an accident or is it a constant change to Xcode?
(Usage: Xcode 7 beta 6, iPhone 4S iOS 7.1)
BAD News: You cannot test your application on iOS 7 simulators. At least not with Xcode 7.3.1. If you are using a previous beta version of Xcode, you should check this answer .
The GOOD news is that you can test it on a real device running iOS 7. I tested my version from Xcode 7.3.1 on iPhone 4 with iOS 7.1.2.
UPDATE : The only way I found to test your application on iOS 7 simulators is to install OS X 10.10 Yosemite and use Xcode 6 (tested with OS X 10.10.5 and Xcode 6.4) next to Xcode 7.
UPDATE : Xcode version has been updated to 7.3.1.
Xcode 7 beta does not support iOS 7.
This is not necessarily a constant change, but a general way beta works.
Once Xcode 7 is released, earlier versions may be supported, and you can test devices running earlier versions.
