@bidm To share keychain items in your apps, enable keychain sharing in app capabilities. Then add the access group, use the access group when you save/load from keychain. Note: the access group includes your app ID prefix implicitly, so you need to specify like AB123CDE45.myKeychainGroup1 for access group.
