I got screwed by the latest build of Xcode iOS 10. My program works great except that the layout is not conforming properly. For my layouts are completely screwed up.
So, I reinstalled Xcode Version 7.3.1 (7D1014) and I got everything working and now I am ready to start testing on my iPhone 6 Plus, except that I am running iOS 10.1.1 and I need to have my phone running iOS 9.
I did find an image file for iPhone7,1_9.0_13A344_Restore.ipsw , sadly it will not allow me to install it.
Sadly I have been doing all my backups by iCloud and I have never done a backup by iTunes.
AM I SCREWED? for trying to install a previous version ???
I did find this article on how to back track, but I have not been successful.
an article that I have found, but I am not successful to installing it.
