How do I read in one entry from a plist array

Question

I am currently reading in an array from a plist using this code

let filePath = Bundle.main.path(forResource: "levelList", ofType: "plist")


if let path = filePath {
    devices = NSArray(contentsOfFile: path) as! [AnyObject]
}

let device1 = devices[0] as! [String: AnyObject]
let device2 = devices[1] as! [String: AnyObject]

If I know before I read from the file that I am only interested in device 1 is there a way to selectively only read in that part of the array?

You mean, only read in that part of the file? – Mike Taverne Feb 23 '17 at 02:26 — Mike Taverne, Feb 23 '17 at 02:26
Can you give more detail on what you want. – Nirav D Feb 23 '17 at 09:00 — Nirav D, Feb 23 '17 at 09:00

If you want to selectively read your plist file only the first device1 value, you should read the file line by line by NSFileHandle. However, you have to decide your terminate point while reading line by line, e.g. when you read to the first </device> tag.

You could check this link out as your reference How to read data from NSFileHandle line by line?

Hope this helps you.

Try this

    let dictionary = NSDictionary(contentsOfFile: Bundle.main.pathForResource("levelList", ofType: "plist")!);
let array = dictionary?["arrayKey"] as! NSArray
print("dictionary=",  dictionary, "\narray =",  array)
