Second video in the Mock Interview Series
In this video, we delve into the Tech Round, focusing solely on iOS-related questions. Take on a variety of topics with varying difficulty levels – from iOS app states to the intricacies of concurrency, from the classic delegate pattern to the modern Combine framework. Explore UI building with both UIKit and SwiftUI.
Covering essentials like structs, classes, performance comparison, dispatch queue, semaphores, locks, UIView lifecycle, event handling, SwiftUI basics, and more. The video also features whiteboard coding for a couple of questions.
Whether preparing for an interview or enhancing your iOS knowledge, this video offers insights and practical demonstrations. Master the intricacies of iOS development, refine problem-solving skills, and boost confidence in facing technical interviews.
