Initializer

init(contentsOf:)

Initializes a newly allocated dictionary using the keys and values found at a given URL.

Declaration

convenience init?(contentsOf url: URL)

Parameters

aURL

An URL that identifies a resource containing a string representation of a property list whose root object is a dictionary.

Return Value

An initialized dictionary—which might be different than the original receiver—that contains the dictionary at aURL, or nil if there is an error or if the contents of the resource are an invalid representation of a dictionary.

Discussion

The dictionary representation in the file identified by aURL must contain only property list objects (NSString, NSData, NSDate, NSNumber, NSArray, or NSDictionary objects). For more details, see Property List Programming Guide. The objects contained by this dictionary are immutable, even if the dictionary is mutable.
