No, you can't use an "earlier" key to create a "later" value - but you can use
code to do basically the same thing.
Or, you can use the same variable that sets your CFBuildNumber to set your

ARC uses the analyzers rules. I was told that if you trust the analyzer (and
follow it's rules), ARC will be fine.

Correct.
main_queue will *always* be on the main thread, but the main thread may be
running a different queue at any specific point in time.
So, if you're *not* on the main thread, throwing code over to the main queue to
execute will guarantee that it's on the main thread - but not vice-versa.
- and even then, it's likely to be based on
SwiftUI, and not C++. It's their competitive advantage, and the reason why
you're looking to *them* to do the work is so that you don't need to. The
problem is that you've waited until the train

The analyzer is great at what it does but it can't be omniscient about your
code.
When you start a method name with "make" or "new" or "create" it assumes that
you're returning a +1 value.
