Is there any good framework that can ease process of syncing strings, structs, bools across devices using icloud.
Currently app doesn't use any cloud functionality.
Any help will be greatly appreciated.
Integrating iCloud for Universal App
A few options. You can check out CloudKit framework: https://developer.apple.com/documentation/cloudkit/
Or Core Data allows data sync between devices: https://developer.apple.com/documentation/coredata/
Or for syncing more simplistic, primitive data you can check out the NSUbiquitousKeyValueStore https://developer.apple.com/documentation/foundation/nsubiquitouskeyvaluestore/
