Key Elements of a Strong Cover Letter
Start with your contact details and the date, followed by the employer's contact information. Keep formatting professional and easy to scan.
Open with a concise statement about the position you are applying for and why you are interested. Mention one relevant achievement or project to catch attention.
Summarize technical skills such as Swift, Xcode, and UIKit, and link them to specific projects. Focus on outcomes, like features you built or bugs you fixed, and the value they delivered.
Explain why you are a good fit for the team and how the internship aligns with your learning goals. End with a polite call to action, offering to provide more details or a portfolio link.
Cover Letter Structure
1. Header
Include your full name, phone number, email, and a link to your GitHub or portfolio. Add the date and the employer's name and address if known, and keep lines short and left aligned.
2. Greeting
Address the hiring manager by name when possible, otherwise use 'Hiring Manager' or the team name. A personalized greeting shows you researched the company and sets a respectful tone.
3. Opening Paragraph
Start with a one-sentence statement of the position you want and how you found it. Follow with a brief hook that highlights one accomplishment or a relevant project, and use specifics to avoid vague claims.
4. Body Paragraph(s)
In one or two short paragraphs, link your technical skills to real work you have done. Describe a project that demonstrates Swift, iOS frameworks, or collaboration with designers and engineers, and quantify results when you can.
5. Closing Paragraph
Restate your enthusiasm for the internship and how you hope to contribute to the team. Offer to share your portfolio or project links and suggest a polite follow-up to continue the conversation.
6. Signature
End with a professional sign-off such as 'Sincerely' or 'Best regards' and your typed name. Include contact details again beneath your name and links to your portfolio or GitHub.
Dos and Don'ts
Tailor each letter to the company and role, mentioning projects or technologies they use. Show that you read the job description and align your examples to their needs.
Lead with one clear achievement or project rather than listing skills. Use active verbs and short descriptions of your role and impact.
Keep the letter to one page and two to three short paragraphs in the body. Recruiters prefer readable letters that are quick to scan.
Include links to your GitHub, App Store submissions, or project demos. Make sure links work and open to polished examples.
Proofread carefully for grammar and formatting errors before sending. Ask a friend or mentor to review for clarity and tone.
Do not repeat your resume line for line, instead expand on one or two highlights. Use the letter to tell the story behind your strongest projects.
Avoid generic phrases like 'hard worker' without examples to support them. Show specific examples that demonstrate the trait instead.
Do not claim senior-level experience if you are an intern candidate. Be honest about your current level and your eagerness to learn.
Avoid long technical dumps or full code explanations in the letter. Save detailed code samples for your portfolio or interview where reviewers can run them.
Do not use casual language or emojis in professional correspondence. Keep tone professional and appreciative.
Common Mistakes to Avoid
Starting with 'To whom it may concern' can feel impersonal. Try to find a hiring manager or use a team name instead.
Overstating impact without context can raise doubts. Provide brief context and measurable outcomes when possible.
Sending broken or private links wastes opportunities. Test links and make repositories public or include screenshots if needed.
Writing a multi-page letter loses attention quickly. Keep it concise and focused on the most relevant points.
Practical Writing Tips & Customization Guide
Mention a recent company project or app update to show genuine interest. Tie that item to a skill or project you worked on.
If you lack professional experience, highlight class projects, hackathons, or open-source contributions. Describe your role and what you learned from each example.
Use one short bullet list for key projects or skills to help recruiters scan your most relevant work. Keep the rest narrative and focused on impact.
Keep your GitHub repo tidy with a clear README and demo instructions. A clean presentation can make small projects look professional.
Sample Cover Letters
Example 1 — Recent Graduate (iOS Internship)
Dear Ms.
I’m a senior in Computer Science at State University and I’m applying for the iOS internship at Nova Health. Last semester I led a team that built a SwiftUI study-planner app used by 120 students; I implemented background sync with CloudKit and cut data sync time from 8s to 2.
5s. I also wrote 40 unit tests and fixed memory leaks that reduced crash reports by 75% in beta.
Outside class, I maintain a GitHub portfolio (github. com/anna-dev) with three iOS projects and a short technical write-up for each.
I’m excited to bring strong Swift fundamentals and a test-first mindset to Nova Health’s patient scheduling team. I’m available to start June 1 and can share code samples or a short demo on request.
Sincerely, Anna Lopez
Why this works: concise metrics (120 users, 75% crash reduction), link to portfolio, clear start date and team fit.

Example 2 — Career Changer (Android → iOS Internship)
Hello Mr.
After two years building Android apps at Brightride (Java/Kotlin), I focused on Swift this year and completed a 40-hour Swift course plus a 6-week guided iOS project. I shipped a personal app to the App Store (1,200 downloads, 4.
4 rating) that uses MVVM and Core Data; I migrated a key feature from synchronous network calls to async/await, which improved perceived load time by 40%. My Android background gives me strong mobile architecture instincts and experience with crash triage tools.
I’m seeking an internship that pairs iOS product work with mentorship. I’d love to discuss how my cross-platform perspective can help reduce time-to-market on your iOS features.
Best regards, Miguel Santos
Why this works: shows measurable impact (1,200 downloads, 40% load improvement), explains transferable skills and recent Swift training.

Example 3 — Experienced Professional Pivoting to iOS (Software QA → iOS Internship)
Dear Hiring Team,
With three years as a QA engineer at FinSecure, I tested mobile payments and automated 85% of regression tests using Espresso. To move into iOS development, I completed two iOS internships-worth projects: a secure login module (Touch ID/Face ID, encrypted Keychain storage) and a spending-tracker app with 500 active users in pilot.
I wrote CI pipelines that run unit/UI tests on every pull request, catching regressions earlier and reducing release rollbacks by 60%.
I bring a strong mindset for testability and product quality, and I want to apply it to building reliable iOS features at ClearWallet. I can start part-time immediately and transition full-time by August.
Regards, Leah Kim
Why this works: emphasizes measurable QA impact (85% automation, 60% rollback reduction), security details relevant to finance, clear timeline for availability.
Actionable Writing Tips
1. Lead with relevance.
Start by naming the role and one concrete match—e. g.
, “iOS intern—built a SwiftUI app used by 120 students”—so the reader immediately sees fit.
2. Use numbers to prove impact.
Quantify users, speed improvements, test coverage, or downloads; numbers make claims credible and memorable.
3. Show, don’t claim skills.
Instead of "strong Swift skills," cite a specific feature you built (e. g.
, implemented async/await to cut load time by 40%).
4. Mirror job-language selectively.
Copy 2–3 keywords from the posting (e. g.
, SwiftUI, REST, Core Data) to pass a quick skim, but avoid stuffing irrelevant buzzwords.
5. Keep it one page and scannable.
Use 3 short paragraphs: hook, evidence, fit/ask. Busy hiring managers should get the point in 20–30 seconds.
6. Demonstrate learning and curiosity.
For internships, mention courses, tutorials, or mentorship experiences and show how you applied them to a real project.
7. Link to proof.
Include one URL to a GitHub repo, App Store listing, or a short demo video and label what the reviewer will see there.
8. Match tone to company culture.
Be concise and energetic for startups; be precise and formal for banks or large enterprises.
9. Close with a clear next step.
State your availability and offer to demo code or complete a short technical task; this reduces friction for scheduling.
10. Proofread for clarity and bugs.
Read aloud, check formatting, and open links to confirm they work—technical roles expect attention to detail.
How to Customize Your Cover Letter
Strategy 1 — Industry focus (tech vs. finance vs.
- •Tech: Emphasize product velocity, app metrics, and platform trade-offs. For example, mention A/B test results, app store conversions, or reducing launch time by a percentage. Companies value feature delivery and user metrics.
- •Finance: Stress security, data handling, and compliance. Cite experience with encrypted Keychain use, secure transactions, or working under PCI/OWASP guidelines, and give numbers (e.g., reduced security incidents by X%).
- •Healthcare: Highlight privacy (HIPAA), reliability, and patient impact. Note any experience with encrypted storage, uptime SLAs, or clinical pilot sizes (e.g., supported 200 patients in pilot).
Strategy 2 — Company size (startup vs.
- •Startups: Show versatility and speed. Describe owning an entire feature (UI, backend calls, test coverage) and a short timeline (e.g., shipped MVP in 4 weeks). Use active language about iteration.
- •Corporations: Prioritize process and scale. Mention experience with CI/CD, testing matrices, or working across teams (e.g., coordinated with backend and QA across 3 teams), and emphasize documentation and code reviews.
Strategy 3 — Job level (entry-level vs.
- •Entry-level: Lead with learning outcomes and small wins. Cite class projects, internships, or personal apps with concrete numbers (users, tests). Show eagerness to learn and a recent concrete skill acquisition.
- •Senior: Focus on leadership, architecture, and measurable business outcomes. Detail how you improved developer velocity (e.g., reduced PR review time by 30%), mentored X engineers, or owned a module that supported Y daily active users.
Implementation tips
1. Use the job posting to pick 3 priorities you will address in the letter (one-sentence hook, two supporting bullets).
2. Swap one paragraph to emphasize the industry-specific detail—security for finance, patient impact for healthcare, product metrics for tech.
3. Adjust tone and length: 3 short paragraphs for startups; a slightly more formal 4-paragraph layout for large firms.
Actionable takeaway: Before writing, spend 15 minutes researching the company product, one recent release note or blog post, and the job description. Then tailor one concrete metric or feature in your opening paragraph to show immediate relevance.
