Recently I have a problem in my team whereas the analytics function become scattered. Some other team create their own function and handling their own caching for tracking the events, and some even create multiple similar function across the modules only for analytics, until then a problem arises.

Factory pattern is one of the common patterns in a programming language. It is one of the creational design patterns that provide a high level of flexibility for your code. One of the interesting use cases that could make Factory pattern become a handy tool to use is Dependency Injection. Normally whenever we want to inject an interface as a dependency on an object, we could easily pass it through the initializer or set it from the property.
The proxy pattern is one of the few underrated patterns that nobody really talks about in iOS. A proxy pattern is one of the structural design patterns that lets you provide a substitute or placeholder for another object. A proxy has total control and access to the original object, and let the proxy object do some magical stuff with the original object and restrict the access to it, however, the one who uses a proxy object, won’t have any knowledge behind the scene.
Have you ever heard about the problem that you need to separate two modules working independently without knowing each other implementation, but requires to be able to communicate easily by only sending necessary data? Most of the advanced use cases will face this real-world use case and we require a more advanced design pattern to be able to solve this pattern to give more scalability to the project. There is a general concept about “Wrapping” an object through an intermediary class that can adapt to each other.
Have you ever have a problem when designing a system that has a similar foundation and capabilities however the ingredients to form the object would vary? We may end up with an easy solution by providing different parameters for each subclass. However, multiple subclasses that need to override the constructor might also have to own those unnecessary properties into its interface. There is one design pattern that also considered as Creational Design Pattern which Android Design pattern by default having this pattern.
