I call `dispatchPrecondition` in my codebase to control on which queues methods and callbacks are executed.

e.g. to make sure a callback is executed on the main queue:

15:24 PM - 14 Nov 2021

Now the only thing I need is an equivalent of this for testing - something like XCTAssertDispatch(condition: .onQueue(.main))

"editor.guides.bracketPairs": true
