Nothing but sugar.

TangramKit is a powerful iOS UI framework implemented by Swift. It integrates the functions with Android layout,iOS AutoLayout,SizeClass, HTML CSS float and flexbox and bootstrap. So you can use LinearLayout,RelativeLayout,FrameLayout,TableLayout,FlowLayout,FloatLayout,LayoutSizeClass to build your App 自动布局 UIView UITableView UICollectionView

Validate GraphQL fields

A super powerful Stack, build flexible layouts with constraints. Similar to ConstraintLayout for Android and AutoLayout for iOS. But the code implementation is much more efficient, it has O(n) layout time complexity and no linear equation solving is required.
