The date up until which to run.
If no input sources or timers are attached to the run loop, this method exits immediately; otherwise, it runs the receiver in the
NSDefault by repeatedly invoking
run(mode: until the specified expiration date.
Manually removing all known input sources and timers from the run loop is not a guarantee that the run loop will exit. macOS can install and remove additional input sources as needed to process requests targeted at the receiver’s thread. Those sources could therefore prevent the run loop from exiting.
