I currently have an app that uses coredata. Many of my users are requesting the data be shared across ipad and iphone. What is the best way to share data between iphone, ipad and even Mac? Tutorials or in depth docs would be great!
I have used iCloud’s key-value file for such sharing. It works well. if you have lots of data you could explore CloudKit.
See the 2019 WWDC sessions on Core Data and CloudKit - There are new capabilities to do sync.
