how to make UIView with equal width and height with SnapKit in Swift?
<p>I want to make a UIView rectangular with SnapKit in Swift, like this</p>

<pre><code>lazy var customView: UIView = {
        let view = UIView(frame: CGRect())
        self.addSubview(view)
        view.snp.makeConstraints({ (make) in
            make.left.top.bottom.equalToSuperview().inset(self.inset)
            make.width.equalTo(make.height)  // Error in this line
        })
        return view
    }()
</code></pre>
