这看起来非常简单,但我已经挣扎了几天才能访问OSX上的日历.我已经打开了App Sandbox功能,并在App Data中勾选了"日历"框.我用以下视图控制器类创建了非常简单的应用程序:

import Cocoa
import EventKit

class ViewController: NSViewController {

    var eventControl = EKEventStore()
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override var representedObject: Any? {
        didSet {
        // Update the view, if already loaded.
        }
    }
}

如您所见,我添加的唯一代码行是导入EventKit并初始化eventControl.

当我在调试中运行它时,我在eventControl初始化行中收到错误
