init(contentsOf:)
Creates a data object from the data at the specified file URL, or returns nil if the system can’t create one.
Declaration
init?(contentsOf url: URL)Parameters
- url:
The location on disk of the data to read.
Discussion
If you specify a malformed URL or the referenced location doesn’t exist on disk, the initializer fails and returns nil. To handle such errors, use NSData/init(contentsOfURL:options:)-5abi3 instead.
