Hyperloop Swift生成失败，类型未知或不支持(AVCaptureSession)

Question

我有一个简单的Swift类，在创建它的XCode 8.1项目中工作良好(类中有更多，但为了简洁起见，示例被削减)。

import UIKit
import AVFoundation
public class ExampleView: UIView {
   let captureSession = AVCaptureSession()
   var previewLayer : AVCaptureVideoPreviewLayer?
   override init (frame : CGRect) {
      super.init(frame : frame)
   }
   convenience init () {
      self.init(frame:CGRect.zero)
   }
   required public init(coder aDecoder: NSCoder) {
      fatalError("This class does not support NSCoding")
   }
   func doSomething(){
      print("do something here.....")
   }
}

And在viewDidLoad()

中使用

let example = ExampleView(frame: self.view.layer.frame);
example.doSomething()

我创建了新的Hyperloop iOS项目(SDK 5.5.1.GA)，并将其与关联的app .js一起添加到src目录中。但每次应用程序编译到Hyperloop编译时都会失败，输出如下

[TRACE] :  [Hyperloop] metabase took 2243 ms to generate
2016-10-30T15:39:31.675Z | ERROR  | An uncaught exception was thrown!
Cannot read property '1' of null
2016-10-30T15:39:31.676Z | ERROR  | Cannot read property '1' of null

所以我试着将这个文件添加到hyperloop-examples项目的src目录中，但是这也给了我以下错误

[TRACE] :  [Hyperloop] metabase took 2425 ms to generate
Swift Generation failed with unknown or unsupported type (AVCaptureSession)     found while compiling /Users/accountone/hyperloop-examples/src/MyExample.swift

我做错了什么，对如何纠正问题有什么建议吗?

是否已将AVFoundation框架添加到appc.js文件中?
