The plist file on disk is written to sporadically. cfprefsd is generally the
arbiter what the real values are, and it may or may not write things to disk
immediately. Conversely, it’s not necessarily sitting around watching the plist
file for changes. The correct way to update user defaults in a
Console should have it. That crash log will have the base address in it that
you can use to symbolicate things.

Option 2 is pretty much what happens. In addition, the behavior of doCoolStuff
might change in 11.0 versus 10.15; the system framework will pick between the
two by checking which SDK you were linked against.

ONLY_ACTIVE_ARCH is set to NO for the build configuration you use for Archiving

Which file are you modifying? The one in your source directory? Because the one
that goes in the final product doesn’t get copied over until after you’ve lost
most control over the build process (it’s done by Xcode after the normal build
stages).

Yes, there is an API for them; it’s part of NSWindow

I couldn’t find a public API, but Metadata.framework defines

Not completely sure if this is what you want, but I think your “scale” would be:
scale = (distance - minDistance) / (maxDistance - minDistance) * (maxScale -
minScale) + minScale
In this case,
scale = (distance - 100) / 100 * 2 + 1
