I did check with codesign. This is the result of "codesign -d --entitlements :-" If I use Archive, Xcode does not build my two dependent modules (the bundle and the launcher) even though in the Schema they are build in the order "launcher, bundle, app" and "Find Implicit Dependencies" is checked. Normally I use "Build for Profiling" which is configured for Release, with a script to do the code signing which has worked from Xcode 4 to Xcode 11. When I try to Archive it, I get output, but also: /Volumes/Vault/Beta/EarthDesk 7.5 β/productbuild:1:1: directory "/Users/trygve/Library/Developer/Xcode/DerivedData/EarthDesk-cxaqpchwzcdrtucehxedgouyvlju/ArchiveIntermediates/Build App Store Package/IntermediateBuildFilesPath/UninstalledProducts/macosx" does not exist for writing "EarthDesk.pkg".

I have filed a DTS incident for this as it is a fairly complex project.

Just an update By changing all the Code Signing Identities to "Apple Distribution" it now is accepted by Transporter, but the app itself does not run and fails under a "spctl -a -v" check, but passes a check with "codesign -v --strict --deep --verbose=2" The internal embedded.provisionprofile seems to have different entitlements than I specified in my --entitlements when signing. Honestly, I spend 40% of my time coding my app and 60% fighting with certificates, signing, entitlements, provisioning and all the other junk that we have to do now. I miss the days of CodeWarrior and even MPW when things just worked.

I am running into this same problem. Checking the code sign gives me: valid on disk satisfies its Designated Requirement and both the main app and helper app have: keycom.apple.security.app-sandbox/key true/ Yet when trying to upload I get: ERROR ITMS-90296: "App sandbox not enabled. The following executables must include the "com.apple.security.app-sandbox" entitlement with a Boolean value of true in the entitlements property list: [( "com.xericdesign.earthdesk.mas.pkg/Payload/EarthDesk.app/Contents/Library/LoginItems/EarthDesk Launcher.app/Contents/MacOS/EarthDesk Launcher" )] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app."

A few people have reported that copying and renaming the 14.5 DeviceSupport folder to 14.6 within Xcode will work.

This is a giant step backwards. One of the nice things about macOS is the built in apache including PHP. Please reconsider this.
