rate as listed

Workload: ~15h/week
Engagement: Project-based
Location: Worldwide
Field: STEM and Coding

Create and refine Swift and iOS development challenges used to train AI models. Review model responses for technical accuracy across UI development, architecture, networking, persistence, concurrency, debugging and app lifecycle topics.

The work

You will write iOS questions and case studies, evaluate AI-generated solutions and provide detailed technical feedback. Scenarios may cover UIKit, SwiftUI, state management, networking, data persistence, memory management, app lifecycle, debugging and mobile architecture. You will also work with other technical experts to calibrate difficulty and keep tasks realistic and educational.

What AfterQuery screens for

Swift is required, along with proven iOS application development experience and knowledge of the iOS SDK. Expect the screening to probe concrete implementation decisions, including UIKit or SwiftUI behavior, architecture patterns, Combine, async/await, Core Data, debugging and performance. Published App Store work, open source contributions, technical writing and experience integrating AI or machine learning into iOS applications are preferred rather than stated requirements.

Logistics

The role is remote, asynchronous and designed for flexible scheduling. No typical weekly hours are stated, so candidates should be ready to describe realistic availability and how consistently they can complete review or challenge-writing work. Pay band: $70/hr

What they look for

Professional iOS application development using Swift
UIKit, SwiftUI and the iOS SDK
Evaluation of code for correctness and iOS best practices
Mobile architecture, state management and app lifecycle reasoning
Networking, persistence, concurrency and memory management
Precise written technical feedback

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This tests whether your claimed iOS experience can be tied to a specific application, code ownership, frameworks and production constraints.
A strong answer: Identify the application, your direct responsibilities, the Swift and iOS technologies used, and one consequential implementation decision. Distinguish your own work from team ownership and mention a verifiable release, repository or technical artifact if available.
Where people lose it: Candidates lose points by summarizing the product while never identifying the screens, services, data flows or architectural components they personally implemented.

Summary, eligibility guidance and screening preparation are prepared by Sidequest from the platform's posting. Check the source listing before applying.
