Platform Fundamentals Questions

Core fundamentals for mobile platforms and cross platform frameworks that interviewers commonly test. For Apple iOS this includes Swift language basics, view and component lifecycle concepts using UIKit and SwiftUI, memory management concepts, and common platform frameworks. For Google Android this includes Kotlin language basics, activity and fragment lifecycle, common architecture components and threading models. For cross platform frameworks such as React Native and Flutter candidates should understand component lifecycles and how platform abstractions map to native capabilities. Questions may probe lifecycle events, rendering, threading, and platform specific constraints.
