iOS Code Review Checklist

Avoid Type Inference
Prefer using Higher Order Functions
Write DRY code (Don’t Repeat Yourself)
Make sure that there are no force unwraps
Make sure that there are no retain cycles
Check if any deprecated API is being used
Check if any hardcoded checks (generally strings) can be changed to enum.
Prefer enum, switch over if else.

SwiftUI Specific Questions

byJeevan

SwiftUI Components & Extension that saves iOSDev time.
### UIKit is **EVENT-Driven** framework - We could reference each view in the hierarchy, update its appearance when the view is loaded or as a reaction on an event.
### SwiftUI is **Declarative, State Driven** framework - We cannot reference any view in the hierarchy, neither can we directly mutate a view as a reaction to an event. 
Instead, we mutate the state bound to the view. Delegates, target-actions, responder chain, KVO .. replaced with Closures & bindings.
