YeahLayout
iOS constraint maker you always wanted. Write constraints like sentences in English.
 Simple. Intuitive. No frightening abstractions. One file.
- You want your 
view's height to be equal to width of other view? Here you go:view.make(.height, .equal, to: .width, of: otherView) - Or some 
view's width to be 100? Even simpler:someView.make(.width, .equal, 100) - Place a view under upper view? You are welcome: 
someView.make(.top, .equal, to: .bottom, of: upperView, +20) - Manage several layout attributes at once, set multipliers and insets? Also possible: 
view.make([.leading, .trailing], .equal, to: [0.5, 0.8], of: otherView, [20, -20]) - Set your constraint's priority? There is a 
*=operator:view.make(.height, .equal, 44) *= 750 
Every make method and *= operator returns you one (or more) NSLayoutConstraint's you can store for later use.
