我刚刚将Swift 1.2代码迁移到Swift 2.0.

此代码以前工作正常.但现在有一个错误说

Redundance Conformance of User to Protocol PFSubclassing (Swift 2.0)

可能是什么导致了这个？

使用swift 1.2,我无法再使用parse子类检索一个poiter数组,并使用另一个parse子类向下转换它.

我总是发现错误:

fatal error: NSArray element failed to match the Swift Array Element type

你有想法还是可能来？

代码:

import Foundation

class ShotModel : PFObject, PFSubclassing {

    /**
    * MARK: Properties
    */
    @NSManaged var name: String

    @NSManaged var pics: [PicModel]


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

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

}

import Foundation

class PicModel : PFObject, PFSubclassing {

    /**
    * MARK: Properties
    */
    @NSManaged var name: …

首先,我知道之前已经提出了类似的问题,并且我尝试遵循此 stackoverflow答案的建议,但无济于事.我也尝试添加这个的基本要点作为评论,但我还没有足够的代表:(基本上我试图使用PFSubclassing来扩展Parse的PFUser模型.因此,这是我的相应代码:

User.swift:

import Foundation
import CoreLocation

class User : PFUser, PFSubclassing {

    override init() {
        super.init()
    }

    convenience init(email: String!) {
        self.init()

        self.email = email
        self.username = email

    }

    // don't need to call User.registerSubclass() in AppDelegate because this
    // is handling that here
    override class func load() {
        self.registerSubclass()
    }

    // Commented out because this is extending PFUser
    //    override class func parseClassName() -> String! {
    //        return "PFUser"
    //    }
}

测试结果:

-[PFObject _loadSensitiveUserDataFromKeychainItemWithName:]: unrecognized selector …

我复制了Subclassing的Parse Swift示例:

class Armor : PFObject, PFSubclassing {

    override class func load() {
        self.registerSubclass()
    }
    class func parseClassName() -> String! {
        return "Armor"
    }
}

我收到以下错误:
