swift - HKWorkoutSessionDelegate未调用

我正在尝试使用HKWorkoutSession开始训练课程。它没有启动会话。

    let workoutConfiguration = HKWorkoutConfiguration()
    workoutConfiguration.activityType = .running
    workoutConfiguration.locationType = .outdoor

    do {
        session = try HKWorkoutSession(healthStore: healthStore!, configuration: workoutConfiguration)
        session?.delegate = self
        session?.startActivity(with: Date())
        print((session?.state)!.rawValue)
    } catch let error {
        print(error)
    }

HKWorkoutSessionDelegate方法
func workoutSession(_ workoutSession: HKWorkoutSession, didChangeTo toState: HKWorkoutSessionState, from fromState: HKWorkoutSessionState, date: Date)
永远不会接到电话。

最佳答案

我已经看过几次了（不足以重现或做任何事情）。
我认为重启Xcode和模拟器有帮助。
