Recently I updated my iPhone 6s to iOS 12.2.
When I went to compile my app, Xcode told me it needed to be upgraded to deploy to device running iOS 12.2.
When I went to upgrade Xcode, it told me my OS needed to be upgraded to macOS Mojave.
When I went to upgrade my Mid 2010 MacBook Pro to Mojave, App Store said “Nah uh, your computer is too old”.
I tried to restore my iPhone to 12.1.4 from the .ipsw, and iTunes says Apple says “Uh um, nope; I decline to authorize…”
Am I separated from my app and data until I pony up for a newer Mac?
