Swift 中的 EventKit 不适用于 Swift 2.0

Question

我正在尝试迁移到 swift 2.0，但并非我的所有代码都能正常工作。我已经成功迁移了大部分代码，但在使用 EventKit 时仍然遇到问题。下面的代码在 swift 1.2 下运行良好。但是现在我有一个问题

import Foundation
import EventKit
import Cocoa

private let _SingletonSharedInstance = EventStore()

class EventStore {
    let eventStore = EKEventStore ()

    class var sharedInstance : EventStore {
        return _SingletonSharedInstance
    }

    init() {
        var sema = dispatch_semaphore_create(0)
        var hasAccess = false

        eventStore.requestAccessToEntityType(EKEntityTypeEvent, completion: { (granted:Bool, error:NSError?) in hasAccess = granted; dispatch_semaphore_signal(sema) })

        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER)
        if (!hasAccess) {
            println("ACCESS", "ACCESS LONG")
            let sharedWorkspace = NSWorkspace.sharedWorkspace()
            sharedWorkspace.openFile("/Applications/System Preferences.app")
            exit (0)
        }
    }
}

以下行导致了问题

eventStore.requestAccessToEntityType(EKEntityTypeEvent, completion: { (granted:Bool, error:NSError?) in hasAccess = granted; dispatch_semaphore_signal(sema) })

我遇到错误

cannot invoke "requestAccessToEntityType" with an argument list of type '(EKEEntityType, completion: (Bool, NSError?) -> ())'

我读到使用 NSError! 应该可以解决问题，但事实并非如此。有任何想法吗？

我找到了答案。 bool 类型已更改为 ObjCBool，EKEntityTypeEvent 已更改为 EKEntityType.Event。

import Foundation
import EventKit
import Cocoa

private let _SingletonSharedInstance = EventStore()

class EventStore {
    let eventStore = EKEventStore ()

    class var sharedInstance : EventStore {
        return _SingletonSharedInstance
    }

    init() {
        var sema = dispatch_semaphore_create(0)
        var hasAccess:ObjCBool = false

        eventStore.requestAccessToEntityType(EKEntityType.Event, completion: { (granted:ObjCBool, error:NSError?) in hasAccess = granted; dispatch_semaphore_signal(sema) })

        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER)
        if (!hasAccess) {
            println("ACCESS", "ACCESS LONG")
            let sharedWorkspace = NSWorkspace.sharedWorkspace()
            sharedWorkspace.openFile("/Applications/System Preferences.app")
            exit (0)
        }
    }
}
