I too am encountering this issue just since updating to XCode 15.0.1. I am using NSLog to report data from an actual Apple Watch device running in debug mode, coded in Objective-C. The watch is now connected directly as a standalone device (which is great and has solved the usual connection issues). But now no NSLogs appear ever, not from any process. Just a blank console. I only need NSLog to report variable values, track when functions are called while debugging my WatchOS app. After decades of "just using it", NSLog appears to have just switched-off! Any advice to see debug logging greatly appreciated. Right now I have to put in breakpoints and inspect which is very slow.
Not sure if this is an XCode 15 issue, or the new way of connecting Apple Watch devices via network (which I like a LOT)
Thanks
