Using iOS 15 devices with Xcode 12.5 (instead of Xcode 13)
# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)
# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport
# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions
# (A similar approach works for older versions too, just change the version number after DeviceSupport)

A generic diffing operation that can calculate the minimal steps needed to convert one array to another. It can be used to generate standard diffs, or it can be used more creatively to calculate minimal UI updates.

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…
