SamuraiTransition is an open source Swift based library providing a collection of ViewController transitions featuring a number of neat “cutting” animations from hachinobu.
SamuraiTransition is easy to implement, your view needs to subclass SamuraiViewController and can be implemented in code or in interface builder.
SamuraiTransition features 9 transition animations, and you can customize the duration, switch between vertical and horizontal animations, line coloring, line width, and more.
