Hi -
I have an .appex that when running in release mode doesn't work since it's relying on app groups to convey important state from the containing app. All works fine in debug mode.
I surmise that the cause has to do with my app-group entitlements for release but not debug builds. I have followed this carefully: https://help.apple.com/xcode/mac/current/#/dev298d7b2cb. And find that:
1. codesign -d -entitlements <path-to-debugbuild>/my.app shows
<dict>
<key>application-identifier</key>
<string>XXXX.com.mycorp.myapp</string>
<key>aps-environment</key>
<string>development</string>
<key>com.apple.developer.team-identifier</key>
<string>XXXX</string>
<key>com.apple.security.application-groups</key>
<array>
<string>group.com.mycorp.myapp</string>
</array>
<key>get-task-allow</key>
<true/>
</dict>
2. where if i unzip a signed/release/buggy app.ipa and issue the same codesign command, i get this:
<dict>
<key>application-identifier</key>
<string>XXXX.com.mycorp.myapp</string>
<key>aps-environment</key>
<string>production</string>
<key>com.apple.developer.team-identifier</key>
<string>XXXX</string>
<key>get-task-allow</key>
<false/>
</dict>
ie: no security.application-groups.
Even more mysteriously, inspection of the <Entitlements> portion of both embedded.mobileprovision files seems to suggest
that all is well.
Can anyone please help? I've recently upgraded to xcode 10 and haven't had such problems with older versions of xcode.
thanks in advance!
