Finally I found the problem. In the entitlements file, I had 2 entries iCloud Container Identifier iCloud Services with an empty array of values. These must have been left over from previous edits. After removing the above entries, building completes without any error. 😉

I was offline for a couple of days. I stepped through the above steps. Step one was working OK. Step 3 was working OK. I have no idea what is going wrong. I think I will revoke my developer certificate an try to start with a fresh one. Xcode must store some information outside of of the source code with is GIT controlled.

Thank you for your replies. Unfortunately, this didn't help either. I developed an app with SwiftDate in a GroupContainer. The data model is stable, and all relationships are optional. The next step should be to switch to an iCloudContainer. Both computers are on the same network and have internet access and access to the developer account. I disabled and re-enabled automatic signing. No change. A comparison of the project.pbxproj files showed two new lines in the non-functional project: 913a913 CODE_SIGN_IDENTITY = "Apple Development"; 948a949 PROVISIONING_PROFILE_SPECIFIER = ""; I manually deleted these two lines and restarted Xcode. There was no change in behavior; the same error occurred. I also manually downloaded the profile from the developer website and tried to sign it manually. But this deployment profile has the same error again: Entitlements: 8 included, 1 Missing What surprises me is that the working version on the MacBook lists 12 entitlements. The entitlements are identical on both systems. <key>aps-environment</key> <string>development</string> <key>com.apple.developer.aps-environment</key> <string>development</string> <key>com.apple.developer.group-session</key> <true/> <key>com.apple.developer.icloud-container-identifiers</key> <array/> <key>com.apple.developer.icloud-services</key> <array/> <key>com.apple.security.application-groups</key> <array> <string>group.de.hjbrede.bredeseck</string> </array> I guess there is something wrong with the signatures. Because my Xcode about is about to expire in the next couple of days, I am thinking of canceling that subscription and than buy a new one with new ids.

Thanks for your answer. I want to clarify the situation. i use automatic signing with Signing & Capabilities editor at the moment iCloud is disabled and not used I have cleaned all derived data - no change. I have reinstalled Xcode - no change. I have delete the project and reloaded it from my git repository - no change. I have loaded the project on my MacBook. - and it compiles without any problem. I have no clue what difference between these to systems is.

Problem is gone: OSX 15.3.2 and Xcode 16.2

Finally I have found a work around. Just append the .frame(height: 200.0) modifier to the VStack with a value large enough to display the table. If the value is too small, the table won't be rendered.
