iPhone - NSData from local file's URL

Question

I have a NSURL object which gives me the path of a local file (in documents folder). I want to populate an NSData object with the contents of this file

Answer 1

// Given some file path URL: NSURL *pathURL
// Note: [pathURL isFileURL] must return YES
NSString *path = [pathURL path];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:path];

Swift code:

let data = FileManager.default.contents(atPath: path)
