任何新的iCloud容器都需要iCloud前缀.较旧的应用程序仍可以继续使用团队标识符前缀，并且对于iCloud Drive照常工作.只要您设置适当的权利，新的带iCloud前缀的容器就可以与iCloud Drive一起使用，也可以不与之一起使用.

The iCloud prefix is required for any new iCloud containers. Older apps can still continue to use the Team Identifier prefix and will work as usual for iCloud Drive. The new iCloud prefixed containers can be used with or without iCloud Drive providing you set the appropriate entitlements.
