uts开发iOS端插件一直崩溃，还找不到原因，同样的代码用原生插件和swift工程测试OK

这是swift的代码，在xcode工程中能正常运行，
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let player = BDAlphaPlayerMetalView.init()
self.view.addSubview(player)

    if let bundlePath = Bundle.main.path(forResource: "TestResource", ofType: nil) {  
        let directory = (bundlePath as NSString).appendingPathComponent("heartbeats")  
        let configuration = BDAlphaPlayerMetalConfiguration.default();  
        configuration.directory = directory;  
        configuration.renderSuperViewFrame = self.view.frame;  
        configuration.orientation = BDAlphaPlayerOrientation.portrait;  
        player.play(with: configuration);  
    }  
}  

开发uts插件，执行 let player = BDAlphaPlayerMetalView.init()这个就崩溃。。。
