Interface Segregation

What is Interfaced Segregation

Making the interfaces smaller
Whenever you have a interface being implemented, you need every one of the methods to be used

This principle requires segregating the interfaces within their minimal possible functionality. If there is one object that uses the functionality of another, it should use the maximum of the provided interface. If the module has methods 1, 2, 3, 4, 5 ,6 and one object uses methods 1, 2 and 3 and another object uses methods 4, 5, 6 then probably it makes sense to have two separate interfaces.

Examples

Javascript

Classes and inheritance instead of Interfaces

Kotlin

Kotlin Syntax#Interfaces

Swift

You can achieve this in swift using Swift Protocols
