iCloud in OS X 10.10 Yosemite Beta
Apple are making big changes to iCloud in iOS 8 and OS X 10.10 Yosemite. They are using a whole new cloud system, and it is completely separate to the existing one.
Apple's plan is to move your data from one cloud system to the next when Yosemite and iOS 8 launch. This will be a one time migration.
This will cause problems for you if you are trying out the OS X Beta. It means that if you run iOS 8 and Yosemite, data goes to a different place in the cloud than on iOS 7 and Mavericks. The two do not mix, so an iOS 7 device cannot sync iCloud data with a Mac running Yosemite Beta.
There is nothing we can do as a developer to influence this. It means you have three choices:
- Don't upgrade to Yosemite until it is released, together with
- If you upgrade to Yosemite, install iOS 8 Beta too.
- Upgrade to Yosemite, but be prepared not to use iCloud until the public release.
Apologies if this has affected you, but it is a result of Apple's transition to new infrastructure, and we can't avoid it.
