Is there a writeToFile equivalent for Swift 3's 'Data' type?
Use write(to: fileURL).
For example:
let fileURL = try! FileManager.default .url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false) .appendingPathComponent("test.jpg")do { try jpegData.write(to: fileURL, options: .atomic)} catch { print(error)}Or, if you really are stuck with a path, convert that to a URL:
do { try data.write(to: URL(fileURLWithPath: path), options: .atomic)} catch { print(error)}But, generally, it's preferable to use URL references throughout your code nowadays, retiring the use of path strings.
