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.
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/
