iOS Developer Cover Letter Example
A worked example for a ios developer application. The App Store links, and whether SwiftUI appears alongside UIKit.
Rachel Lindqvist
Head of Engineering
Northbridge Software
Dear Ms. Patel,
I am applying for the iOS Developer position at Northbridge Software. I have spent 8 years in this field, most recently as Senior iOS Developer, and the work described in your posting is close to what I do now.
The result I would point to first is that I led the incremental SwiftUI migration of a 180,000-line UIKit app, shipping module by module with no release freeze. Day to day my work centres on Swift, SwiftUI and UIKit, which maps directly onto what this role calls for. I have attached my resume, which sets out the rest in the same terms.
[Add one genuine, specific reason you want to work at Northbridge Software — a product, a recent announcement, or how the team works. One real sentence beats a paragraph of praise.] I would welcome the chance to talk about where I could be most useful.
Thank you for your time and consideration.
Adapting this for a ios developer application
Paragraph one: the role, and why you are credible
Name the exact job title and where you saw it, then one line establishing that you already do this work. Skip "I am writing to express my keen interest" — it spends a sentence saying nothing.
Paragraph two: one achievement, with a number
Choose the achievement most relevant to the posting rather than the one you are proudest of, and attach a figure: a percentage, an amount, a volume, a timeframe. One specific result beats three general claims and gives the interviewer something concrete to ask about.
What this field is judging behind the words
iOS processes almost always include a take-home or live exercise in Swift, plus questions on memory management, concurrency and the view lifecycle. Hiring managers frequently download the apps you list before the call, so contributions have to be described accurately. Where the codebase is large and old, expect UIKit questions regardless of how the posting is worded, and be ready to discuss incremental migration rather than rewrites.
Paragraph three: why this employer
This is where most letters fail. "I admire your commitment to excellence" could be sent to anyone. Name something real — a product, a recent announcement, how the team works, a market they are moving into — and connect it to your own experience. If you genuinely cannot find anything specific to say, that is worth noticing before you apply.
Mistakes that cost ios developer candidates
- Claiming an app you contributed one screen to without saying so
- Listing Objective-C and Swift as equals when your last Objective-C work was six years ago
- Ignoring App Store review and release mechanics, which is a large part of what senior iOS engineers are trusted with
Those are resume mistakes, but they apply to the letter for the same reason: both documents are read by someone deciding quickly whether you understand the job.
What this role needs on paper
There is no licence and no certification of consequence for iOS work. Apple offers a Swift certification through Certiport that is aimed at students rather than working developers. A computer science degree helps at large employers with automated filters, but a shipped app in the store is the credential the field actually respects.
Where this leads if you get it
Junior to mid to senior, then either staff or principal on the individual track, or mobile engineering management. Many senior iOS engineers broaden into cross-platform work or take ownership of the whole mobile release process, which is a distinct and valued specialism.
Before you send it
Reread the letter for the previous employer's name — reusing a letter and leaving the old company in it is the most common fatal typo there is. If you are applying in the UK, the National Careers Service sets out what employers there expect alongside a CV. Then run the resume that accompanies it through our free ATS checker. The letter gets you read; the resume is what the applicant tracking system scores.
iOS Developer Cover Letter Questions
What should a ios developer cover letter say?
Three short paragraphs: the role you are applying for and why you are credible, your single strongest relevant achievement with a number attached, and one genuine reason you want this employer. Anything past one page usually goes unread.
Do employers hiring ios developers actually read cover letters?
It varies by employer and it is rarely the deciding document. It matters most for competitive roles, career changes and gaps, where a resume alone handles the context badly. When the application asks for one, always include it.
What does this field want to see in the letter?
The App Store links, and whether SwiftUI appears alongside UIKit. Say it in the first two lines rather than saving it for the second page.
Should I repeat my resume in the letter?
No. The resume already lists what you did. The letter answers the two questions a list cannot: why this role, and why this employer. Pick the achievement most relevant to the posting and give it context.
Where does this career usually go from here?
Junior to mid to senior, then either staff or principal on the individual track, or mobile engineering management. Many senior iOS engineers broaden into cross-platform work or take ownership of the whole mobile release process, which is a distinct and valued specialism.
How long should it be?
Roughly 250 to 350 words on one page. The three-paragraph discipline forces you to lead with what matters instead of restating the resume.
Can I copy this example?
Use the structure and the job each paragraph does, but write your own content. The employer and candidate here are fictional, and a letter describing work you did not do will not survive an interview.
