XCode 15 - Missing Error Messages

I have somehow managed to switch off the error messages that come up as you are typing co9de in, I don't know how I did it, and I can't switch them back on, as they are very useful, please could someone tell me how to switch them back on.

How did you switch them off ?

Normally you select Show issues navigator (at the top of the left panel of Xcode-.

Then ay the bottom, you have a Filter line. Click on the rightmost icon to turn on / off (show errors only or all warnings as well).

I have absolutely no idea what I did to turn them off, but I have followed your advice to no avail. I still hasver no error messages.

I can't believe this, I shutdown my iMac overnight and now the error messages are back???????
