How do I generate a Swift Runtime warning message?

Question

I would like to add a warning that shows up like the "Main Thread Checker" in the Issue Navigator under the Runtime tab.

I have used assert() in the past but I don't want to cause a crash, just note the issues in the navigator.

I want the error to only show if the code is run and not at compile time.

Maybe the answer is that one doesn't exist?

This looks promising, if you haven't seen it already: https://stackoverflow.com/questions/46372548/how-to-log-a-warning-that-shows-up-as-a-runtime-issue-in-xcode — TylerP, Apr 16 '20 at 08:22

#warning("My message")

#error("Some Error")

I use this feature frequently to mark some TODOs: #warning("TODO: Some work")

I'm looking for a *Runtime* warnings / errors, those are compile time errors – Bobby Rohweder Apr 16 '20 at 08:16
@BobbyRohweder You said you wanted the message to show in the Issues Navigator which is where compiler warning/error messages are displayed. Perhaps you could specify your requirements more accurately. – trojanfoe Apr 16 '20 at 08:24

Im sorry, I was trying to be clear with `under the Runtime tab`, where the main thread checker reports them. – Bobby Rohweder Apr 16 '20 at 08:27
