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.
