Unity automatically adds Game Center and Push notifications Capabilities to Xcode project, if you have code using those features e.g.

Social.localUser.Authenticate(ProcessAuthentication);
NotificationServices.RegisterForNotifications(NotificationType.Alert, true);

Xcode capabilities then make Xcode require those entitlements in the provisioning profile and then it's not possible to use wildcard provisioning profiles e.g. for Enterprise distribution

To reproduce:

1. Download attached project "New Unity Project (11)" and open in Unity
2. Open "SampleScene" scene
3. Build for iOS
4. Open the Xcode project
5. Select "Unity-iPhone" from the project navigator in Xcode
6. Select "Capabilities" see Game Center and Push Notifications enabled

Expected results: Observe that Game Center and Push Notifications are disabled
Actual results: Observe that Game Center and Push Notifications are enabled

Notes:
- On Unity 2018.2.0a1 it started to add Push Notifications
- On Unity 2018.3.0a8 it started to add Game Center
