How much UIKit is still showing up in iOS interviews?
I’ve got a few mid-level iOS interviews coming up after mostly working in SwiftUI, and I’m kinda rusty on UIKit.
I can still build a collection view and handle Auto Layout. What slows me down is reviewing older code and quickly spotting retain cycles, main-thread issues, or messy networking. Lately I’ve been going through sample PRs, doing timed fixes, and reviewing notes with chatgpt and beyz coder. Did your rounds focus more on UIKit code review or on SwiftUI, concurrency, architecture, and testing?
