xcode playground中的EXC_BAD_INSTRUCTION（代码= EXC_I386_INVOP，子代码= 0x0）

Question

我正在尝试为我的游乐场创建一个集合视图类。我有这个代码。我在Xcode playground中创建一个UICollectionView后会在我的主文件中使用它。

这是我的代码：

import UIKit
import SceneKit

public class MenuCollectionView: UICollectionView, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout  {
    public init(frame: CGRect) {
        let layout = UICollectionViewFlowLayout()
        super.init(frame: frame, collectionViewLayout: layout)

        self.dataSource = self
        self.delegate = self
        self.backgroundColor = UIColor(red: 0, green: 0, blue: 38, alpha:1.0)

        self.register(MenuCollectionViewCell.self, forCellWithReuseIdentifier: "MenuCell")
    }

    required public init(coder aDecoder: NSCoder) {
        fatalError("This class does not support NSCoding")
    }

    public func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
        return 1
    }

    public func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10
    }

    public func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "MenuCell", for: indexPath) as! MenuCollectionViewCell

        cell.PlanetName.text = Constants.names[indexPath.row]
        cell.PlanetImage.image = UIImage(named: Constants.imagesNames[indexPath.row])?.cropToSquare().cropToCircle()

        return cell
    }

    public func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return CGSize(width: (self.frame.size.width/2)-10, height: (((self.frame.size.width/2)-10)*1.4)+25)
    }

    public func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        let cell = collectionView.cellForItem(at: indexPath) as! MenuCollectionViewCell

        self.tag = indexPath.row

        UIView.animate(
            withDuration: 0.3,
            delay: 0.0,
            usingSpringWithDamping: 1.1,
            initialSpringVelocity: 1.5,
            options: UIViewAnimationOptions.curveEaseInOut,
            animations: ({

                cell.PlanetImage.transform = CGAffineTransform(scaleX: 1.1, y: 1.1)

            }), completion: {finished in
                NotificationCenter.default.post(name: NSNotification.Name(rawValue: "MenuItemSelected"), object: nil)

                UIView.animate(
                    withDuration: 0.3,
                    delay: 0.0,
                    usingSpringWithDamping: 1.1,
                    initialSpringVelocity: 1.5,
                    options: UIViewAnimationOptions.curveEaseInOut,
                    animations: ({

                        cell.PlanetImage.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)

                    }), completion: nil)
        })


    }

    public func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {
        return UIEdgeInsetsMake(0, 5, 0, 5)
    }

    public func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 5
    }
}

当我使用下一行代码时出现该错误：

let menuView1 = MenuCollectionView(frame: CGRect.init(x: -(viewWidth/2.2), y: 0.0, width: viewWidth/2.2, height: viewHeight))

运行项目时出现的错误是：

  

EXC_BAD_INSTRUCTION（代码= EXC_I386_INVOP，子代码= 0x0）。
  该过程一直处于被中断的位置，使用“thread return -x”返回到表达式求值之前的状态。

我的Xcode版本是9.2，我使用的是Swift 4.如果您有任何疑问，请发表评论，我会提供有关错误的更多信息。
