Is it possible to write a cross-platform app that syncs user's data between an iOS device, as well as his or her Android device, if the "comparable application" is running on both devices, and, of course, both devices are signed in to the same Apple ID? Thank you. (I noticed in the WWDC 2015 video, titled: "What's New In CloudKit," the presenter indicates that this framework "requires a comparable application for iOS or OS X." I'm wondering if that's what he meant...)
CloudKit JS & Web Services in Android App?
You're allowed to use the javascript framework to build a web app, so I would assume you would be able to wrap the Cloudkit stuff in a web view on Android. But who knows? I do iOS/OS X only and I just had a native Mac app get rejected for syncing user data (I'm hoping to get more info on the rejection).
iCloud API is pretty nice to use, I'd rather use it than some third party alternative. The App Review policy on iCloud's proper use I think needs a bit more transparency.
looks like you can use the following library
