Key Elements of a Strong Cover Letter
Start with your name, email, phone, and a link to your GitHub or portfolio. Include the date and the employer's contact details so the reader can quickly find your information.
Begin with a short sentence that states the role you want and why you are excited about it. Mention one specific detail about the company or its product to show you researched the role.
Highlight Swift skills, APIs, and frameworks you have used and connect them to a small project or class assignment. Use concrete examples and links so the reader can review your code or demo quickly.
End with a brief statement of interest and a clear next step, such as asking for an interview or offering a code walkthrough. Thank the reader for their time and include your preferred contact method.
Cover Letter Structure
1. Header
Place your name in bold at the top followed by your email, phone number, GitHub or portfolio link, and the date. Below that add the hiring manager's name, company, and address when available so your letter looks professional.
2. Greeting
Address the hiring manager by name when you can, for example Dear Ms. Rivera or Dear Hiring Team if you cannot find a name. A personal greeting shows you put in effort to research the company.
3. Opening Paragraph
Open with one or two sentences that state the internship you are applying for and why you are excited about the company. Mention a specific product, recent announcement, or company value to show you did background research.
4. Body Paragraph(s)
Use one paragraph to summarize your technical background and another to describe a project that shows your Swift skills and problem solving. Include specific technologies you used, what you built, and a short result or lesson learned to make your experience tangible.
5. Closing Paragraph
Close with one or two sentences that restate your interest and offer to discuss your work in an interview or a short demo. Thank the reader for their time and suggest the best way to reach you for next steps.
6. Signature
Sign off with a professional closing such as Sincerely or Best regards followed by your full name. Beneath your name add links to your GitHub, portfolio, and LinkedIn so the reviewer can find your work.
Dos and Don'ts
Do tailor each letter to the company and role by referencing a product or team focus. This shows focus and makes your letter stand out.
Do highlight one or two Swift projects with links so the reader can see your code or demo. Short descriptions help the reviewer understand your contribution.
Do keep the letter to one page and use clear, concise sentences to respect the reader's time. Recruiters read many applications so clarity helps you.
Do explain what you learned or accomplished rather than listing technologies. Employers want to see outcomes and growth.
Do proofread for typos and correct function or framework names to maintain credibility. Small mistakes can distract from your skills.
Don't repeat your entire resume verbatim in the letter because it wastes space and adds no new value. Use the letter to highlight context and motivation.
Don't use vague phrases like I am a hard worker without examples that show that trait. Show evidence with a short project story.
Don't overclaim experience with senior-level responsibilities you have not done. Be honest about your role and what you learned.
Don't include unrelated personal details that do not support your fit for the internship. Keep the focus on skills, projects, and motivation.
Don't send a letter with broken links or no links to code when you reference projects. Make sure all links work before submitting.
Common Mistakes to Avoid
Being too long or using dense paragraphs makes your letter hard to scan. Keep paragraphs short and focused on a single idea.
Using jargon or acronyms without explanation can confuse nontechnical recruiters. Define terms or give brief context for clarity.
Failing to show outcomes makes projects feel vague and unfocused. Mention what you built and what changed because of your work.
Forgetting to personalize the letter turns it into a generic note that is easy to pass over. A sentence about the company fixes this quickly.
Practical Writing Tips & Customization Guide
Include one link to a small, well-documented Swift project that runs or has clear screenshots so reviewers can verify your work quickly. A single strong example beats many weak ones.
Mention the Swift version and key frameworks you used, for example SwiftUI or Combine, to show current knowledge. This helps match you to specific team needs.
If you contributed to an app store build or a group project, describe your specific role and the parts of the codebase you owned. Clarity about responsibility increases trust.
Keep your tone confident but humble by focusing on learning and impact rather than guarantees. Employers value curiosity and the ability to grow.
Cover Letter Examples
Example 1 — Recent Graduate (iOS/Swift Internship)
Dear Hiring Manager,
I’m excited to apply for the iOS Swift Developer internship on your mobile team. I recently graduated with a B.
S. in Computer Science (3.
7 GPA) and built a SwiftUI app for campus transit that I published to TestFlight with 1,200 invitations and a 4. 6 average tester rating.
In that project I implemented Combine for asynchronous updates, Core Data for offline caching, and reduced app launch time by 35% by deferring heavy tasks to background threads.
I contribute to an open-source library with 120 GitHub stars, where I fixed memory leaks and improved unit test coverage from 40% to 78%. I’m eager to bring my hands-on Swift experience and strong testing habits to your team at [Company].
I’m available to start in June and would welcome a short call to discuss how I can support your Q3 roadmap.
Why this works: This letter pairs measurable results (1,200 TestFlight users, 35% faster launch) with matching technical skills and a clear next step.

Example 2 — Career Changer (Android to iOS Intern)
Dear [Hiring Manager],
After three years building Android apps, I’m transitioning to iOS and applying for your Swift internship. On Android I led a feature team of four that cut average API response handling time by 40% and increased feature release cadence from monthly to biweekly using CI/CD.
To prepare for iOS, I completed a 12-week Swift course, rebuilt our feature in Swift using MVVM and async/await, and shipped a demo that passes XCTest with 92% success across critical flows.
My background in mobile architecture, REST APIs, and observability gives me a fast ramp-up advantage. I already know how to work in cross-functional teams and can contribute to your instrumentation and release pipeline from day one.
I’d welcome the chance to show the demo and discuss where I can add immediate value.
Why this works: It shows transferable metrics (40% improvement), training completed, and a clear plan to contribute immediately.

Example 3 — Experienced Professional Seeking Internship to Pivot
Hello [Recruiter Name],
I’m an experienced software engineer (6 years) pursuing a focused iOS internship to pivot into native app development. At my current role I drove a reliability initiative that cut crash rates by 60% and mentored three junior engineers.
Over the past year I’ve authored three Swift packages, implemented Swift Concurrency patterns, and automated UI tests to run nightly (reducing manual regression time by 70%).
I want an internship where I can learn platform-specific best practices under senior iOS engineers while contributing to feature work and test automation. I offer proven coaching skills, a track record of measurable quality improvements, and immediate familiarity with Git, CI, and release workflows.
I’m available to start in May and would appreciate a 20-minute conversation.
Why this works: It combines leadership outcomes (60% crash reduction) with concrete Swift experience and a clear learning goal.
Actionable Writing Tips
1. Open with a specific role and source.
Mention the job title and where you found it in the first sentence so the hiring manager immediately understands intent.
2. Lead with measurable impact.
State one clear achievement (e. g.
, “reduced app launch time by 35%”); numbers grab attention and demonstrate results.
3. Mirror keywords from the job posting.
If the listing asks for Swift Concurrency, UIKit, or TestFlight experience, name those skills to pass both human and automated screens.
4. Keep tone confident and concise.
Use active verbs (built, improved, reduced) and avoid passive phrasing; aim for 3–4 short paragraphs under 250 words.
5. Show one technical detail.
Briefly describe a tool or technique you used (e. g.
, Combine for async data streams) to prove depth without drowning in jargon.
6. Connect to the company’s work.
Reference a product, repo, or public metric and explain in one sentence how you can help move it forward.
7. Address gaps directly.
If you lack years of experience, highlight relevant projects, coursework, or fast-learning examples with timelines.
8. End with a clear next step.
Propose a meeting window or offer to provide a demo or GitHub link to make follow-up easy.
9. Proofread for one purpose: clarity.
Read aloud to catch awkward phrasing and remove filler words that dilute impact.
10. Format for skimming.
Use short paragraphs and one bulleted line if needed; hiring managers scan quickly, so make your value obvious.
Customization Guide: Industry, Company Size, and Job Level
Strategy 1 — Tailor by industry
- •Tech: Emphasize product metrics and platform specifics. Example: “Improved UI render time by 25% on iOS using lazy loading and Instruments.” Mention frameworks (SwiftUI, Combine) and automation (CI tests).
- •Finance: Focus on security, latency, and compliance. Example: “Implemented certificate pinning and reduced API latency by 15ms; familiar with SOC2 concepts.” Highlight encryption, audit logging, and accuracy.
- •Healthcare: Stress reliability and privacy. Example: “Built offline sync that maintained HIPAA-compliant encryption and achieved 99.7% successful sync rate.” Note regulatory awareness and testing for edge cases.
Strategy 2 — Customize for company size
- •Startups: Show breadth and speed. Say you shipped three end-to-end features in six months, owned release notes, and triaged production bugs. Startups value a generalist who moves quickly.
- •Corporations: Emphasize process and cross-team impact. Quantify how you worked with QA, product, and security to reduce regression cycles by 30% or scaled a feature to 200k users.
Strategy 3 — Adjust for job level
- •Entry-level/Intern: Highlight learning outcomes and projects. Mention classroom projects, GitHub repos (e.g., “demo app with 50+ stars”), and willingness to pair-program.
- •Senior roles (or experienced pivoters seeking internships): Focus on leadership and measurable outcomes—mentoring numbers, crash rate reductions, delivery cadence improvements—then state why you want hands-on iOS mentorship.
Strategy 4 — Use concrete signals and one-call-to-action
- •Include 1–2 metrics, one brief technical example, and one specific next step (demo link or 20-minute call). For example: “I can share a 5-minute demo of the SwiftUI onboarding flow I built; are you available Tuesday morning?”
Actionable takeaway: For every application, change three elements—first sentence (role + source), one metric that aligns with the employer’s priorities, and the closing call-to-action—so each letter reads tailored and intentional.
