Ok, some more info: After waiting several minutes (about 5) the task seems to complete and I can navigate Localization.xcloc. However closing Localizable and opening it again starts whatever is happening again. So the hang is not permanent. Simply opening Localizable.xcloc file directly outside of the project using XCode 16 seems to work without delay and not cause a hang. The XCode is running at 100% CPU usage during the hang. Attached a sample of what's going on with XCode a few minutes into waiting for it to finish whatever it is doing, after clicking on Localizable file in the IDE. Sample of XCode

Hi there - yes, I sent the crash log using the reporter tool popping up after killing XCode + a brief explanation about what I was doing. If it helps I can provide the offending Localizable.xcloc file along with additional details if needed.

Yeah, this message constantly popping up during debug is a new normal since Ventura 13.3. Does not seem to affect anything though and things work just fine.

This super annoying bug came up after upgrading to 14.3. Project path is ok, so it must be something else.

The fix is of course to replace all DEPRECATED(13.0 to DEPRECATED(10.8 in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/CoreGraphics.framework/Versions/A/Headers/CGDisplayStream.h Still, it is a shame Apple shipped this in such a state.

This is not right even in the final 14.3...

Hope this will be fixed otherwise I won't be able to use 14.3...

The app BetterDisplay (https://betterdisplay.pro) can both read and override (!) the EDID on Apple Silicon, so both are definitely doable

You might want to try BetterDummy to create any HiDPI resolution you'd like, even on sub-4K external displays (which do not allow HiDPI by default on M1 macs).
