Several app developers share their issues with iCloud synchronization

iCloud was introduced many years ago, however, developers still see issues with syncing data in their apps using Core Data.

NetNewsWire, Overcast developers (as well as others) share their thoughts in couple of blog posts.

Most developers report long syncing time and overall unreliability of the service. Moreover, according to internal app statistics, it sees that about 10% of users do not have iCloud meaning that they did not entered their Apple ID in system settings.

Overall recommendation to developers who plan to use iCloud is to have an alternative by either having their own sync solutions (self-hosted or using some public cloud offering), or rely on third-party as data storage (NetNewsWire allows to use multiple RSS aggregators in addition to iCloud).

Developers now can transfer apps that use iCloud

Apple prevented transfer of the applications between developers if the application used iCloud containers or key-value storage. Well, not anymore.

Now Apple allows this kind of application transfer. This provides an opportunities to indie developers to sell their apps to other developers even if they were using iCloud.
