Subclassing PFObject in Swift

Question

The Parse documentation for adding properties and methods on PFObject subclasses conveniently skips the Swift syntax in their sample code listing just the Objective-C syntax

Answer 1

Swift 1.2

First: Create a swift file and define the subclass. Don't forget to import Parse! (for example Armor)

import Foundation
import Parse


class Armor: PFObject, PFSubclassing {

    // MARK: - PFSubclassing

    override class func initialize() {
        struct Static {
            static var onceToken: dispatch_once_t = 0;
        }
        dispatch_once(&Static.onceToken) {
            self.registerSubclass()
        }
    }

    class func parseClassName() -> String {
        return "Armor"
    }


    // MARK: - Parse Core Properties

    @NSManaged var displayName: String?

}

Note: You can define your properties as optionals. Every "undefined" value inside the Parse Core Manager will be translated to "nil".

Second: Register all subclasses, inside your AppDelegate.swift.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    // MARK: - Parse Setup
    Parse.setApplicationId("YOUR_ID", clientKey: "YOUR_KEY")

    // MARK: - Parse Register Subclasses
    Armor.registerSubclass()

    return true
}
