Hire iOS developers by skill

Which screening questions work for iOS roles?

Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the iOS library.

1. Q1 When do you still use UIKit in a SwiftUI app?
2. Q2 How do you keep UI updates on the main thread with Swift concurrency?
3. Q3 Tell us about an App Store review problem and how you solved it.

What does the iOS coding task look like?

Trip list with offline cache. Build a SwiftUI list that loads trips, caches them for offline use and supports Dynamic Type. Time limit 90 minutes.

1. Load trips with async and await
2. Cache results and show them offline
3. Show loading, empty and error states
4. Test the view model logic

@MainActor final class TripsModel: ObservableObject {
    @Published private(set) var trips: [Trip] = []
    func load() async {
        trips = (try? await api.trips()) ?? cache.trips()
    }
}

How much does a iOS developer cost?

Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior iOS developers. Treat them as a starting point and check current surveys for your market.

Senior iOS engineers with a track record of shipped apps often earn at the top of the mobile range.
