Hire iOS Developers
who actually ship Apple apps that feel native

With EasyEnv we build a fit test for the role. Use it to cut the noise at the top of the funnel, or to go deep on the candidates who matter.

You can even evaluate how this person works with AI. So you hire the engineer who can ship, not the one who looks good in a slide.

Zero install for candidates

Auto-graded

Pass / fail checks per challenge

Plus the full session replay

A great iOS developer reads Instruments the way other developers read logs. The good ones think in main-actor versus background, ship Dynamic Type and VoiceOver from day one, and never trust a closure capture they did not annotate. EasyEnv puts the candidate in a real Xcode project with a real bug a tester filed.

You

Refactor calculate_total to use Decimal for currency math, and add a test.

How it works

Three steps. Zero infra to maintain.

Pick the fit test

Use a ready-made challenge or ask us to build one for your stack. Live, take-home, or both.

Send one link

The candidate clicks. A full Linux workspace boots in their browser. No installs, no VPN, no zoom-share.

Review at 2x

Replay the session, read the auto-graded checks, and decide. Most reviews take under five minutes.

The problem

Why hiring a iOS Developer is hard.

SwiftUI and UIKit fluency rarely overlap evenly. The interview has to find the depth.

Concurrency is the trap. async/await with actors is its own paradigm.

Accessibility is not a CV bullet, it is a habit you can see in the code.

App Store policy and review cycles are real engineering constraints.

The fit test

What we measure for a iOS Developer.

Every area runs inside a real production-like workspace. The candidate works in a browser, the session records itself.

SwiftUI debugging

A view that refreshes on every tap. They read the body invalidations and fix.

Concurrency model

A data race hidden behind a closure. They explain main-actor isolation before they patch.

Performance and memory

A scrolling list that drops frames. Instruments is one click away.

Accessibility

A form that fails VoiceOver. They fix labels and traits, not just colors.

Build and CI

An xcodebuild that fails on CI but works locally. They read the actual log.

AI collaboration

Allow AI for boilerplate and grade whether they ran on a device, not just a preview.

The stack we put in front of them.

Real tools, pre-installed, accessible from the workspace terminal.

Sample challenges

What a iOS Developer interview looks like.

Pick from our library or ask us to build a challenge for your stack. Each one is a real workspace, not a snippet.

Challenge 01

The view that refreshes too much

Scenario

A SwiftUI list where every row redraws on every tap. The candidate has the full project.

What you learn

Whether they use @StateObject and Equatable views, not just hacks.

In the workspace

$ ls challenges/

workspace, runbook.md, README.md

candidate has:

· a real Linux box in the browser
· kubectl, docker, terraform, jq, yq
· cluster, repo and cloud creds pre-wired
· auto-checks running in the background

interviewer sees:

· every keystroke + every command
· terminal + screen recording
· auto-graded pass/fail per check

AI in the loop

Score the engineer, and how they work with AI.

AI is happy to write SwiftUI that thrashes the body. EasyEnv records prompts so you see whether the candidate ran the Time Profiler after the LLM-suggested refactor.

Allow or block AI per question, not per interview

Full prompt and response history replayed in the review

Score "verifies AI output" as a separate signal

Role FAQ

Hiring a iOS Developer, answered.

Live workspaces include a cloud Mac with the simulator. Enterprise plans can connect a tethered device for the session.

Yes. Either can be pre-loaded with a seeded store and a known bug.

No. The workspace runs in their browser. Terminal, editor, ports and dashboards are all served from the EasyEnv workspace, so candidate setup is zero.

Each challenge has automated checks (did the service come back, did the test pass, did the right log message appear) plus a recording your team can replay. Most reviews take under five minutes.

Yes. AI access is a per-interview setting. Block it for fundamentals, then allow it later in the loop to assess AI collaboration separately.
