Issue Description

I trying to create an aspect ratio constraint 1:1. How can I achieve that?

[rafagan]

In swift I've done in that way:

extension UIView {
    func aspectRatio(_ ratio: CGFloat) -> NSLayoutConstraint {
        return NSLayoutConstraint(item: self, attribute: .height, relatedBy: .equal, toItem: self, attribute: .width, multiplier: ratio, constant: 0)
    }
}

In snapkit:

view.snp.makeConstraints { (make) in
      make.width.equalTo(view.snp.height).multipliedBy(1.0 / 1.0)
}
