“Use default container” doesn't show in iCloud

问题:

I want set up iCloud sync for CoreData using CloudKit.

But when I add iCloud in Capabilities and enable CloudKit checkbox, Use default container don't appear as described in the Doc:

Instead, I got this:

Maybe I'm missing something?

回答1:

This changed in Xcode 11, there no longer is a default container checkbox.

Instead you have to create your own container. Just press the + and enter your bundle-id. Xcode will automatically prefix it with iCloud.

So the result will be iCloud.<your app’s bundle ID>, the same as the default Xcode used previously.

This seems to be a useful tutorial, updated with changes in Xcode 11: https://www.raywenderlich.com/4878052-cloudkit-tutorial-getting-started
