displayedProperties
The properties (such as name or telephone number) the picker displays when it shows a person.
Declaration
var displayedProperties: [NSNumber]? { get set }Discussion
Objects in the array are instances of NSNumber that represent ABPropertyID values.
The name property is always displayed if available.
To have the picker display a single property for the person displayed, such as the telephone number, set displayedProperties to an array with a single value, such as kABPersonPhoneProperty.
