我想在我的apple watchOS应用程序中访问实时心率.在主题演讲中,他们强调开发人员现在可以访问实时数据.但我在文档中找不到任何相关内容.

有人对我有暗示吗？

我正在WatchOS上构建一个非常简单的锻炼应用程序:其中一个功能是在训练期间提供音频反馈.我可以在显示器打开时播放文件,但是当显示器很暗时,手表不会播放我的文件.

有人可以查看我的快速代码并帮助我弄清楚我错过了什么吗？

这是我的extensionDelegate.swift:

var audioPlayer = AVAudioPlayer()

class ExtensionDelegate: NSObject, WKExtensionDelegate {
    func applicationDidFinishLaunching() {
        let audioSession = AVAudioSession.sharedInstance()
        do {

        } catch {
            print("audiosession cannot be set")
        }
        do { try audioSession.setActive(true) }
        catch {
            print ("audiosession cannot be activated")
        }

        let test = URL(fileURLWithPath: Bundle.main.path(forResource: "1", ofType: "m4a")!)
        try! audioPlayer = AVAudioPlayer(contentsOf: test)
        audioPlayer.prepareToPlay()
        audioPlayer.play()
    }

    func applicationDidBecomeActive() {
        // Restart any tasks that were paused (or not yet started) while the application was …
