What is dependancy injection in swift?

Hey Pravesh,

 

Please check below links for better understanding.

 

Dependency Injection is often used with the intention of writing code that is loosely coupled, and thus, easier to test. When we use dependency injection in our code, we are essentially giving an object its instance variables. What this means is that instead of giving our object the responsibility of creating it’s own dependencies, we inject the dependencies to the object instead.
