Provide uniform type identifiers (UTIs) in order from highest fidelity to lowest. If your app employs a native data representation, place that first in the array.
Implement this version of the property to offer a minimal list of UTIs that all resulting item provider instances can support. For example, using this version of the property for an
NSURL object, your implementation should return the
public UTI but not
Use the class version of this property when you do not initialize an item provider with an object, thereby deferring the underlying object’s instantiation until the destination app needs it.
