GTEasyLayout is a small framework written in Swift which aims to minimise the effort of setting up constraints programmatically when implementing UI in iOS apps. It’s the perfect tool to use when constraints are not extremely complicated and typing a bunch of similar lines for multiple views becomes tiring and anti-productive. Check it out on GitHub!
Create Auto Layout constraints programmatically and above all easily using SnapKit; A great tool for working fast with constraints in Swift.
This tutorial will show to you how to create Autolayout constraints using the Auto Layout Visual Format Language and programmatically by calling the proper iOS SDK APIs. Go through it and master constraints.
