I have a working C++ Xcode 11.1 project on Mojave. I've copied it over to a Catalina system, but Xcode 11.5 won't build it ("can't locate the C++ template named 'deque'"). On both Mojave and Catalina

Xcode 11.2.1, macOS Mojave 10.14.6, ObjC This morning Xcode decided to stifle all NSLogs in _one_ of my macOS development apps. printfs and fprintf(stderr,*) still get written to the Xcode debug windo

Ok next question - this should be obvious but has stopped me. First I am running Objective-C applications (simple ones so far) as command line applications. So I have the syntax figured out, etc. I ca

Is it just my luck - or is Xcode 11 unusable? I just finally updated to Catalina and installed Xcode 11 (all latest versions of course). Xcode 11 is totally non-responsive. In Interface Builder, when

Mac OS 10.15.2 Xcode 11.5 Don’t call your app SwiftUI. If you create an iOS Single View project and name your app something like Sample, the app will be able to build and preview. If you misguidedly y
