Overview

Sets the iCloud automatic backup flag for files in the system.DocumentsDirectory and system.ApplicationSupportDirectory on macOS and iOS systems.

The iCloud backup is true by default and must be set false with this API to disable automatic backup of files to iCloud.

This function returns up to two values:

value (Boolean) — true if synchronization was successful, false if it failed. Returns nil on Android and Windows systems since they don't support this API.
errStr (String) — Error message if value returned false.

Gotchas

This function is for macOS and iOS platforms only.
