Swift 3 - ＆＃34;＆gt;＆gt;＆gt; - ＆＃34;生成NSLayoutConstraint，而不是预期的上下文结果类型＆＃34; Void＆＃34;

Question

自Swift 3起，我收到此错误：＆＃34;＆gt;＆gt;＆gt; - ＆＃34;生成NSLayoutConstraint，而不是预期的上下文结果类型＆＃34; Void＆＃34; （又名＆＃34;（）＆＃34;）在我的项目中。

fileprivate func configurateCell(_ cell: BasePageCollectionCell, backImage: UIImage?) {
    cell.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(cell)

// add constraints
[(NSLayoutAttribute.width, cell.bounds.size.width), (NSLayoutAttribute.height, cell.bounds.size.height)].forEach { info in
  cell >>>- {
    $0.attribute = info.0
    $0.constant  = info.1
  }
}

[NSLayoutAttribute.centerX, .centerY].forEach { attribute in
  (view, cell) >>>- { $0.attribute = attribute }
}
cell.layoutIfNeeded()


}
