SBAutoLayout is an extension for UIView that makes it easy to perform common auto layout operations in Swift without having to write verbose auto layout syntax.

## A few examples

Pin to superview center with height and width:

```

view.pinWidth(100)

view.pinHeight(100)

view.pinToSuperviewCenter()

```

Some views can be positioned with only one line of code:

```

view.pinToSuperviewAsTopStrip(height: 50)

```

All methods return generated constraints. Handy for if you need to remove or change them later. 

```

let topConstraint = view.pinToSuperviewTop(60)

view.pinToSuperviewBottom(40)

view.pinToSuperviewLeading(15)

view.pinToSuperviewTrailing(15)

// ...Later

topConstraint.constant = 30

```

Multiple views? Sure.

```

blueView.pinToSuperviewCenter()

blueView.pinHeight(100)

blueView.pinAspectRatio(width: 1, height: 1)

orangeView.pinToSuperviewCenterX()

orangeView.pinHeight(80)

orangeView.pinAspectRatio(width: 1, height: 1)

orangeView.pinAboveView(blueView, separation: 10)

```
