I'm working on two Swift applications which are using QUIC in Network.framework for communication, one serve as the listener (server) and the other serve as the client so that they can exchange data, both the server and the client app are running under the same LAN, the problem I met is that when client try to connect to the server, the connection will fail due to boring SSL, couple questions: Since both the server app and client app are running under the same LAN, do they need TLS certificate? If it does, will self-signed certificate P12 work? I might distribute the app in App Store or in signed/notarized dmg or pkg to our users. If I need a public certificate and self signed wouldn't work, since they are just pair of apps w/o fixed dns domain etc, Is there any public certificate only for standalone application, not for the fixed web domain?

After I upgraded to macOS 15.3, all of my current Xcode project have the signing issue, I spent half day and I didn't make any progress, I tried two projects, one is Swift AppKit App calling one C++ dylib, another one is a pure Swift AppKit app, when I build, there will be error: Warning: unable to build chain to self-signed root for signer "Apple Development: Steven Tang (XXXXX)" /Volumes/TwoTSSD/steventang/Library/Developer/Xcode/DerivedData/ImageEnhancement-ddbilgyraofrdyfeljyuknusunza/Build/Products/Release/ImageEnhancement.app: errSecInternalComponent I tried remove account, add account back in Xcode, none of it worked, also tried ChatGPT's WWDR updating and it won't help.

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.

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?

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
