无法将类型 'String?' 的值分配给类型 'CKRecordValue'

Question

随着最新 Beta 版本中 Swift 的更新，这不再有效，我很困惑。我可能需要添加其他东西，我已经尝试将 let 更改为 var 并将 ! 添加到 recordType["username"] 和 password。我对此很陌生，所以任何方向都将不胜感激！

import UIKit
import CloudKit

class LoginViewController: UIViewController {

    @IBOutlet weak var username: UITextField!
    @IBOutlet weak var password: UITextField!

    let publicDatabase = CKContainer.default().publicCloudDatabase

    override func viewDidLoad(){
        super.viewDidLoad()
    }

    @IBAction func LoginTapped(sender: AnyObject){

        var recordType = CKRecord(recordType: "Login")

        recordType["username"] = username.text <-Cannot assign value
        recordType["password"] = password.text <-Cannot assign value

        publicDatabase.save(recordType) {
            (record, error) in

            if error == nil {       
                print("Created Successfully")
            }

            else {           
                print(error?.localizedDescription)
            }
        }
    }
}

Answer 1

尝试：

recordType["username"] = username.text! as NSString
recordType["password"] = password.text! as NSString

无法将类型 'String?' 的值分配给类型 'CKRecordValue'

Cannot assign value of type 'String?' to type 'CKRecordValue'
