swift - 无法在 Xcode Playgrounds 中初始化 UICollectionView

Question

我尝试初始化一个 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

要初始化 UICollectionView 使用 init(frame: CGRect, collectionViewLayout: UICollectionViewLayout)，勾选 Apple Doc:

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