Apple

's keychain group sharing allows groups of apps to share information that is stored on a device's keychain. Keychain group sharing is required when you are developing multiple inter-related apps. The setting is part of a project's build.

To enable keychain group sharing in an

Xcode

project:

Open the app's project file.
Click the application target >
Capabilities
tab.
Turn on
Keychain Sharing
.
You may be asked for your developer password and to choose a development team. The provisioning profiles for each app must come from the same team and must share the same App ID prefix (see below).
In the 
Keychain Group
field, type
com.good.gd.data
.

If the settings for keychain group sharing change, it is recommended to do a fresh reinstall of the new version of the app, instead of upgrading the old version. This ensures that the new keychain settings take effect.

An App ID prefix is a unique ID that groups a collections of apps and enables those apps to share keychain and UIPasteboard data. Apps that share keychain data must have a common App ID prefix from

Apple

.

For more information, see Technical Note TN2311: Managing Multiple App ID Prefixes.

Apple

App ID prefix is completely independent of the
