Question 3

Which ecosystem libraries should I screen for - Kotlin or Swift?

Accepted Answer

For Kotlin we look for working experience with Android, Jetpack Compose, Coroutines. For Swift the equivalents are SwiftUI, Combine, UIKit. Both ecosystems get surfaced on every Haystack profile so you can filter on exact tooling.

Question 4

Can the same engineer cover both Kotlin and Swift?

Accepted Answer

Often yes - particularly when both stacks live in the same category (Languages vs Mobile). On Haystack we let you require both as primary or secondary skills; senior generalists typically carry one as their main stack and one as supporting.

Question 5

Should I bet on Kotlin or Swift for a greenfield project?

Pick on hiring depth, your team's current strengths and the ecosystem fit. Kotlin suits android apps with jetpack compose and kotlin multiplatform; Swift suits consumer ios apps with swiftui and combine. We can shortlist both in parallel so you can interview against the same brief.
