A dictionary containing strings to be appended to URLs.
- iOS 9.0+
- Mac Catalyst 13.0+Beta
When the Filter Data Provider determines that a string should be appended to the request URL for a new flow, it creates a
NEFilter object using the
URLAppend class method. The system uses the
URLAppend method to look up the corresponding string in this dictionary. The system then appends the string to the flow’s request URL.
