Ios 在swift 4.1中添加子视图自致崩溃

我有一个自定义视图，其init方法如下所示。在使用swift 4的Xcode 9.1中，这一功能可以正常工作。今天我更新到了Xcode 9.3，并将项目基础设置为swift 4.1，它开始在这个init方法中崩溃

init(frame: CGRect, detailDic: [[String:AnyObject]], parentView:UIView)
    {

        super.init(frame:frame)
        self.view = Utilities.loadViewFromNib(“MyScoreView", atIndex: 0, aClass: type(of: self),parent:self) as! UIView
        self.view.frame = frame
        self.view.autoresizingMask = [UIViewAutoresizing.flexibleWidth, UIViewAutoresizing.flexibleHeight]
        self.view.isHidden = true
        finalScoreTable.register(UINib(nibName: “MyScoreTableViewCell", bundle: nil), forCellReuseIdentifier: "scoreCell")
        addSubview(self.view)
        parentView.addSubview(self) //Crashes here
        finalScoreTable.tableFooterView = UIView()
    }

共享崩溃日志。。。！！！parentView.addSubview（self）将self替换为self。view@HarshalValanda我试过了。仍然崩溃。@YagneshDobariya，添加堆栈trace@sonu能否显示

numberofrowsin节：

方法？
