无法在Xcode Playgrounds中初始化UICollectionView

Question

我尝试初始化UICollectionView：

import UIKit
import PlaygroundSupport

let collectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))

但我得到的只是

error: Execution is interrupted, reason: signal SIGBART

Answer 1

要使用init(frame: CGRect, collectionViewLayout: UICollectionViewLayout)初始化UICollectionView，请检查Apple Doc:

let collectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: 100, height: 100), collectionViewLayout: UICollectionViewFlowLayout())
