formatIdentifier
A string uniquely identifying the format of the adjustment data.
Declaration
var formatIdentifier: String { get }Discussion
Set this identifier when you create an adjustment object with the init(formatIdentifier:formatVersion:data:) method. For best results, identify your organization or product using a reverse-DNS-style name, such as com.example.myApp.
Read this property, and the formatVersion property, to determine whether the adjustment data saved with an asset was created by your app or is otherwise compatible with your app.
