swift - Homekit触发器，如何调用

Question

我正在观看有关 Homekit 的 WWDC 2018 视频，更准确地说是有关触发器的视频。我正在尝试使用此代码片段来创建日落存在触发器。我想在该功能运行时打开一盏灯。我已经有了turnOn 函数，但如何在此触发器中实现它？提前致谢!

func createSunsetPresenceTrigger(withName name: String, actionSet: HMActionSet, home: HMHome) {
        var offset = DateComponents()
            offset.minute = -10

        let sunsetEvent = HMSignificantTimeEvent(significantEvent: .sunset, offset: offset)

        let presence = HMPresenceEvent(presenceEventType: .atHome, presenceUserType: .currentUser)
        let predicate = HMEventTrigger.predicateForEvaluatingTrigger(withPresence: presence)
        let trigger = HMEventTrigger(name: name, events: [sunsetEvent], predicate: predicate)

        home.addTrigger(trigger) { (error) in
            guard error == nil else { return }

            trigger.addActionSet(actionSet) { error in
                guard error == nil else { /* Handle error */ return }

            }
        }
    }

您需要创建一个HMActionSet，并将该灯的功率特征值设置为“true”，并添加HMTrigger这个函数

open func addActionSet(_ actionSet: HMActionSet, completionHandler completion: @escaping (Error?) -> Void)
