Questions that cover making apps easier to use for everyone. Tip: For more kinds of interview preparation and career guidance, see my Swift Career Guide. To get started, select a category, then select a question that interests you. Obviously my idea of "easy" or "hard" won't exactly match yours, but hopefully it at least lets you focus your attention more easily. Questions are grouped by category, and I've also tried to provide some idea of difficulty using a traffic light system. So, browsing through a few and testing yourself is a great way to prepare. Not questions "like these" or "based on these" – companies literally use these exact questions. These questions are used by companies around the world in their interviews. If you're a Swift developer preparing for your next job interview, this page is perfect for you: I've collected over 150 of the top interview questions about iOS, Swift, UIKit, SwiftUI, and more, and also provided suggested approaches to answering each question.
