Capability - nimblehq/github-notifications-mac GitHub Wiki

A capability grants the application access to an app service provided by Apple. To use some app services, we must provision our app, adding a capability with Xcode’s project editor that configures the app service correctly for us. All capabilities are included in the provision profiles. Currently, we only have Keychain Sharing in the project.

Keychain Sharing

Keychain Sharing enables apps to share keychain items with each other by adding the apps to an access group. This allows the application to read and write data from Keychain.
