We have a large project with dozens of sub-projects and different targets. These targets differ in user interface for different feature sets with a large block of shared code between these targets. The subprojects is a mix of static libraries, Custum Framework, which are written in Swift, ObjectiveC, ObjectiveC ++, C ++, C. We are currently working on porting the ObjectiveC part of the apps to Swift.Most of the time when we are switching from one target to the other we are facing this kind of error during the compilation of swift code.This happens in all Xcode 10 and Xcode 11 version (even in the latest Beta)<unknown>:0: error: module 'XXXX' is defined in both '/Users/abc/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/2ZWTI7P1QZ7I1/XXXX-KFQM8A0MFP4Q.pcm' and '/Users/abc/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/2ZWTI7P1QZ7I1/XXXX-2OMJXFAAVMK3W.pcm'<unknown>:0: error: cannot load underlying module for 'XXXX'Does anyone have any idea what triggers the generation of the different .pcm files? Or how the hash of the pcm is calculated so that I can search for the cause.

I developed a Audio Server PlugIn, based on the SimpleAudioDriver sample. It works fine on my development machine. Now I want to distribute it with the rest of our app. For that I set up the CODE_SIGN_IDENTITY parameter for our Developer ID Application certificate. Build and signment works fine. Now I put everything together in an installer package and try to install it on different machines, but the driver was rejected and did not work. I also tried to notarise the package but did get an error saying that my code isn't signed at all. And indeed the _CodeSignature/CodeResources file inside my driver did not have an entry for the binary. Any ideas what I made wrong or what I did miss?

We have a huge app with many frameworks. I want to use address sanitizer with it. After enable it in Xcode and recompile the app does not start. dyld[73936]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[73936]: Library not loaded: /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation   Referenced from: <926AEF5E-4934-3EA0-BC60-64CC0A28EC0C> /Users/schmitt/Library/Developer/Xcode/DerivedData/TeamViewerWorkspace-bzqkzpkzdmerjreghjwkjpbhtmua/Build/Products/Debug/TeamViewer.app/Contents/MacOS/TeamViewer   Reason: tried: '/Users/schmitt/Library/Developer/Xcode/DerivedData/TeamViewerWorkspace-bzqkzpkzdmerjreghjwkjpbhtmua/Build/Products/Debug/Foundation.framework/Versions/C/Foundation' (no such file), '/Users/schmitt/Library/Developer/Xcode/DerivedData/TeamViewerWorkspace-bzqkzpkzdmerjreghjwkjpbhtmua/Build/Products/Debug/PackageFrameworks/Foundation.framework/Versions/C/Foundation' (no such file), '/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation' (no such file), '/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation' (no such file, no dyld cache), '/Library/Frameworks/Foundation.framework/Versions/C/Foundation' (no such file) It looks like Foundation.framework is no longer found. When I try the same thing with a new app from the macOS app template and link it to our frameworks, the app launches normally. I have tried playing with the deployment target, but have no luck getting any clues as to what is going wrong

The are some errors in the macOS 13.3 SDK from current Xcode 14.3 Beta2 All CGDisplayStream... Calls are now flaged like this CG_EXTERN CGError CGDisplayStreamStop(CGDisplayStreamRef cg_nullable displayStream)   CG_AVAILABLE_BUT_DEPRECATED(13.0, 14.0, "Please use ScreenCaptureKit API's stopCaptureWithCompletionHandler: to stop a stream instead"); in macOS 13.0 SDK this call was flagged only flagged with CG_EXTERN CGError CGDisplayStreamStop(CGDisplayStreamRef cg_nullable displayStream)    CG_AVAILABLE_STARTING(10.8); The Error here is the in MacOS 13.3 SDK it should be something like CG_AVAILABLE_BUT_DEPRECATED(10.8, 14.0, "Please use ScreenCaptureKit API's ...
