Add the following line to your Cartfile.
github "isair/ManualLayout"
Then do carthage update. After that, add the framework to your project.
Add the following line in your Podfile.
pod "ManualLayout"
Just import ManualLayout in your code and use the methods and properties provided by the library to layout your views. You can check out the cheat sheet below for a compact list of everything. There are also example projects to get you started.
The smart assign operator =~ has only one job; to make your life easier.
someView.origin =~ (0, 20)
anotherView.size =~ (100, 100)
yetAnotherView.frame =~ (0, 120, view.width, 100)// For fast positioning.
var origin: CGPoint
var x: CGFloat
var y: CGFloat
var center: CGPoint
var centerX: CGFloat
var centerY: CGFloat
var top: CGFloat
var right: CGFloat
var bottom: CGFloat
var left: CGFloat
// For fast sizing.
var size: CGSize
var width: CGFloat
var height: CGFloat
// Alternate edges. Their names may change in the near future.
var top2: CGFloat
var right2: CGFloat
var bottom2: CGFloat
var left2: CGFloatThe difference between alternate edges and normal edges require a bit of explaining. Imagine we have a view at position (0, 0) of size (100, 100) named myView. If we do myView.right = 200, then its position is now (100, 0) and its size remains unchaged. However, back when our view was located at (0, 0), if we had done myView.right2 = 200, then myView would have still been at (0, 0) but would have had a size of (200, 100).
So basically, setting a normal edge's position drags the whole view along with that edge but setting an alternative edge's position drags just that edge. And don't worry if you, for example, try to drag a left edge past its view's right edge. Edge swapping is done automatically so you don't have to worry about it.
Just one method with two variants for now, and those are used for easy size calculations.
func sizeToFit(width: CGFloat, height: CGFloat) -> CGSize
func sizeToFit(constrainedSize: CGSize) -> CGSizeSo let's say that you have a label inside a view and you want to lay it out with an inset of 4 points on all sides, you could easily do the following:
myLabel.sizeToFit(inset(myView.size, 4))
myLabel.origin =~ (4, 4)Done!
var contentWidth: CGFloat
var contentHeight: CGFloat
var contentTop: CGFloat // Always equal to 0. Read-only.
var contentLeft: CGFloat // Always equal to 0. Read-only.
var contentBottom: CGFloat // contentHeight alias.
var contentRight: CGFloat // contentWidth alias.
var viewportTop: CGFloat // contentOffset.y alias.
var viewportLeft: CGFloat // contentOffset.x alias.
var viewportBottom: CGFloat // conentOffset.y + view height
var viewportRight: CGFloat // contentOffset.x + view widthAll UIViewController properties are read only. They offer easy read access to a controller's view's properties.

var center: CGPoint
var centerX: CGFloat

var height: CGFloat
var top: CGFloat // Top layout guide y coordinate.

var bottom: CGFloat // Bottom layout guide y coordinate.
var left: CGFloat // Always equal to 0.These functions never modify the view/layer/rectangle/etc they are passed.
