Simple Swift file download with URL

Question

So I have the URL as string (in this case a JPG but would like a general procedure for any file type if possible) and I have the file path as string where I want to save the fil

Answer 1

With Swift 4, the code will be:

if let url = URL(string: myURLstring) {
    let imageDataFromURL = try Data(contentsOf: url)
}

Answer 2

If you're writing for OS X, you'll use NSImage instead of UIImage. You'll need import Cocoa for that - UIKit is for iOS, Cocoa is for the Mac.

NSData has an initializer that takes a NSURL, and another that takes a file path, so you can load the data either way.

if let url = NSURL(string: myURLstring) {
    let imageDataFromURL = NSData(contentsOfURL: url)
}

let imageDataFromFile = NSData(contentsOfFile: myFilePathString)
