What Interviewers Evaluate

Frequently Asked Questions

Should I focus on SwiftUI or UIKit?

Learn both. SwiftUI is the future direction, but UIKit remains essential for complex UI requirements and legacy codebases. Most companies need engineers comfortable with both, and interoperability between them is commonly tested.

Is Objective-C still tested?

Rarely as a primary language, but understanding Objective-C runtime concepts, bridging headers, and how to work with legacy Objective-C code is valuable, especially at companies with mature iOS codebases.

How important is design sense?

Apple places high value on design quality, and iOS engineer interviews often assess your understanding of Human Interface Guidelines, accessibility standards, and attention to detail in UI implementation.

Do I need to know server-side Swift?

Not typically required, but awareness of Vapor or server-side Swift shows breadth. Focus on core iOS skills, concurrency, and framework knowledge first. Server-side Swift is a nice differentiator.
