Swift - read plist file to array?

Question

I created a mini translation from English words to Spanish words. I would like to use englishArray.plist instead of my englishArray = ["cat"] How can I create this?

I also used locizable.strings to retrieve the "cat" value for "el gato", but I would like to get this from englishArray.plist

I started with this, but not sure I'm on the right track

let path = NSBundle.mainBundle().pathForResource("englishArray", ofType: "plist") 
let plistEnglishArray = NSArray(contentsOfFile: path!)

Here is the rest of my code:

var englishArray: [String] = ["rainbow", "boots", "heart", "leaf", "umbrella", "tired", "angry", "cry", "the cat" ]


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.translateTextField.delegate = self
    picker.delegate = self
    picker.dataSource = self
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func translateButtonTapped(sender: UIButton) {

    let emptyString = self.translateTextField.text

    if (emptyString!.isEmpty) {

        print("please enter a word")

    }

    for transIndex in englishArray.indices {
        if englishArray[transIndex] == emptyString!.lowercaseString {

            //englishArray

            //translateLabel.text = "\(spanishArray[transIndex])"
            translateLabel.text = NSLocalizedString(emptyString!.lowercaseString, comment:"")


            print(emptyString)
            return

        }
    }
}

Change the object rootto Array, then

var myEnglishArray: [String] = []
if let URL = NSBundle.mainBundle().URLForResource("englishArray", withExtension: "plist") {
      if let englishFromPlist = NSArray(contentsOfURL: URL) as? [String] {
        for myEnglish in englishFromPlist {
          myEnglishArray.append(myEnglish)
        }
      }
    }

"englishArray.plist" english. , .

, , , . , , - .

import Foundation

You can use Codable , which is a clean fast type.

First load the Plist file from bundle, then usePropertyListDecoder

Full code -

    func setData() {
        // location of plist file
        if let settingsURL = Bundle.main.path(forResource: "JsonPlist", ofType: "plist") {

            do {
                var settings: MySettings?
                let data = try Data(contentsOf: URL(fileURLWithPath: settingsURL))
                    let decoder = PropertyListDecoder()
                settings = try decoder.decode(MySettings.self, from: data)
                print("array  is \(settings?.englishArray ?? [""])")//prints array  is ["Good morning", "Good afternoon"]


            } catch {
                print(error)
            }
        }
    }
}
struct MySettings: Codable {

    var englishArray: [String]?

    init(from decoder: Decoder) throws {
        let values = try decoder.container(keyedBy: CodingKeys.self)
        englishArray = try values.decodeIfPresent([String].self, forKey: .englishArray)

    }
}

The absolute easiest way to do this is to

    let url = Bundle.main.url(forResource: "Sounds", withExtension: "plist")!
    let soundsData = try! Data(contentsOf: url)
    let myPlist = try! PropertyListSerialization.propertyList(from: soundsData, options: [], format: nil)

The myPlist object is an array or dictionary, depending on what you used as the basis of your plist.
