Debug Vision Pro application directly on physical device instead of the simulator
I have Mac mini M4 with 16GB memory, the Xcode is 16.1, when I test my Vision Pro App with the Simulator, it is very slow and system shows the memory is under the high pressure. How do I run/test/debug the application on Vision Pro directly? Tried to add my Vision Pro to my developer account, it didn't work due to cannot find UDID, when I hook the USB to the battery, it only shows Battery device ID.

Test Vision Pro App on Vision Pro
This might be a very silly question, anyway I tried many ways and didn't find a solution: My Mac mini M4 is basic version which only has 16GB memory, it is very shy for developing Vision Pro application and testing with the simulator (CleanMacX always warning me low memory), I want to debug and test the application directly on Vision Pro (+ my app need both two hands gestures which simulator might not support) in stead of simulator, is there any proper instructions on how I test/debug/run the App on VP device directly instead of on simulator in favor of speed?

Xcode 16 project build malfunction
I have one project, it has one Swift (AppKit) App and one C++ dylib project, I don't have problem in build the dylib, but when build the UI App, there will be an error: "ld: multiple errors: file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/AppDelegate.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/AppDelegate.o'; file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/ViewController.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/ViewController.o'; file cannot be open()ed, errno=2 path=/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/GeneratedAssetSymbols.o in '/Users/steventang/Library/Developer/Xcode/DerivedData/doodle-girdwlxpmnbetjdldjvdgddoetub/Build/Intermediates.noindex/doodle.build/Debug/doodle.build/Objects-normal/arm64/GeneratedAssetSymbols.o' clang++: error: linker command failed with exit code 1 (use -v to see invocation)" Clean project folder and rebuild - it won't fix I tried remove the two Swift files and added it again- it won't fix Delete DerivedData folder - it won't fix I upgraded to Xcode 16.1 - also tried above, it won't fix BUT: the project doesn't have any problem when build with Xcode 15
