無不與預期參數類型兼容「NSLayoutAnchor <NSLayoutDimention>」

這是有問題的代碼無不與預期參數類型兼容「NSLayoutAnchor <NSLayoutDimention>」

// auto layout 
    let vertivalConstraint = textField.centerYAnchor.constraint(equalTo: self.codeView.centerYAnchor) 
    let leadingConstraint = textField.leadingAnchor.constraint(equalTo: self.codeView.leadingAnchor, constant: 10) 
    let trailingConstraint = textField.trailingAnchor.constraint(equalTo: self.codeView.trailingAnchor, constant: -10) 
    let heightConstraint = textField.heightAnchor.constraint(equalTo: nil, constant: 37) 
    NSLayoutConstraint.activate([leadingConstraint, vertivalConstraint, trailingConstraint, heightConstraint])

讓heightConstraint在標題返回錯誤。我將如何去解決這個問題。

感謝

這是在GitHub上發現了一個自動完成腳本並轉換爲最新的快速。需要值來激活NSLayout Contraint –

也許嘗試：

// auto layout 
    let vertivalConstraint = textField.centerYAnchor.constraint(equalTo: self.codeView.centerYAnchor) 
    let leadingConstraint = textField.leadingAnchor.constraint(equalTo: self.codeView.leadingAnchor, constant: 10) 
    let trailingConstraint = textField.trailingAnchor.constraint(equalTo: self.codeView.trailingAnchor, constant: -10) 
    let heightConstraint = textField.heightAnchor.constraint(equalToConstant: 37) 
    NSLayoutConstraint.activate([leadingConstraint, vertivalConstraint, trailingConstraint, heightConstraint])

我使用：

.constraint(equalToConstant: 37)

代替：

.heightAnchor.constraint(equalTo: nil, constant: 37)
