Figure 7-1. Xcode 5 now has an iCloud panel for real time testing

You can now see the amount of storage space used and space available, what is uploading or
downloading, and the UIDocuments you have stored for the current user.

The file transfer graph is shown in Figure 7-2 . This tool becomes invaluable in testing an iCloud
account by letting you see exactly what is happening and when it happens.

Security Considerations
Guard the credentials to your Apple developer accounts. This is vitally important. Not only should
you keep any developer accounts safeguarded, but your account credentials should be complex
enough to prevent someone from cracking them with brute force. If someone has access to your
developer accounts, it potentially gives them the ability to release an app with the same Bundle
Seed ID. Because Apple uses the Bundle Seed ID to constrain access to user data in iCloud
between different organizations, if an attacker were to issue a provisioning profile with your Team
ID, it would allow them to access the user's iCloud containers and ferry that information back to
themselves.
