Engineering Hiring Manager
[Company name]
[City, State]

Dear [Hiring manager's name],

At Harborlight Financial I own the iOS codebase for a consumer banking app with 640,000 monthly active users, and I'm applying for your iOS Developer role because shipping weekly to a banking app, where a bad release costs real trust, is exactly the discipline I've built over the past several years.

I migrated 34 of our 56 screens from UIKit to SwiftUI over 18 months, shrinking view-layer code by 38% while crash-free sessions held at 99.8% the entire time. I also profiled our startup sequence with Instruments and deferred non-critical work past first frame, taking cold launch from 2.9 seconds down to 0.9.

I work daily in Swift and SwiftUI, ship through a Fastlane and Xcode Cloud pipeline on a weekly cadence, and I built the app's VoiceOver and Dynamic Type support to full WCAG conformance, lifting our accessibility audit score from 61% to 100%. I review about 15 pull requests a week and run the architecture guild that sets our MVVM conventions.

I'd welcome a conversation about where [Company name]'s iOS app could use that same combination of speed and accessibility work. I'm glad to walk through the SwiftUI migration or the accessibility project in more detail. Thank you for your time.

Sincerely,

Ethan Anderson

Why this letter works

  1. Paragraph 1

    Names MAU on a banking app specifically

    640,000 monthly active users on a banking app tells a hiring manager the real trust stakes behind this candidate's release discipline, which is more convincing than naming iOS experience in general.

  2. Paragraph 2

    Two numbers, a migration and a launch-time fix

    A 38% code shrink with 99.8% crash-free sessions held throughout, plus a 2.9-to-0.9-second cold launch fix, gives 2 separate, checkable proofs of both migration and performance skill.

  3. Paragraph 3

    A 61-to-100-percent accessibility jump, stated plainly

    Reaching full WCAG conformance and a 100% audit score is a specific, verifiable claim that most iOS candidates can't make, and it signals depth well beyond typical UI polish.

Questions about iOS developer cover letters

Do usage metrics belong in an iOS developer cover letter?

Yes, when you can verify them. Monthly active users, crash-free session rates, and cold launch times give a hiring manager concrete proof your code performs in production, not just that it compiles and ships.

Should I mention SwiftUI experience even if the posting focuses on UIKit?

Mention both if you have them. Most teams are migrating toward SwiftUI, so showing you can maintain existing UIKit code while contributing to a modernization effort signals flexibility hiring managers value.

How important is accessibility work in an iOS developer cover letter?

Increasingly important, especially for regulated industries like banking. A specific result, like reaching full WCAG conformance, proves depth that goes beyond typical UI work most candidates describe.

How technical should an iOS developer cover letter get?

Specific enough to name real frameworks and one meaningful metric, but not a code walkthrough. One clear technical decision and its measured outcome does more than a list of every API you have touched.
