Key Elements of a Strong Cover Letter
Start with your name, email, phone number, and LinkedIn or GitHub link so hiring managers can contact you easily. Include the date and the employer's contact information when possible to make the letter feel tailored and professional.
Lead with a short, specific reason you are excited about the role or company to grab attention early. Mention a relevant project or coursework briefly to show you know what the role needs.
Summarize your hands-on Swift work, internships, or personal apps and focus on outcomes you achieved or skills you practiced. Describe one or two technical details that show you understand Swift fundamentals and iOS development workflows.
End by restating your interest and inviting next steps, such as a conversation or coding challenge. Keep the tone confident but humble and thank the reader for their time.
Cover Letter Structure
1. Header
Place your full name at the top followed by your email, phone number, and a link to your GitHub or portfolio. Add the date and the hiring manager's name and company details if you know them to make the letter feel personalized.
2. Greeting
Open with a direct greeting using the hiring manager's name when available to show you did some research. If you cannot find a name, use a professional greeting that addresses the team or role.
3. Opening Paragraph
Start with one or two sentences that show enthusiasm for the role and mention the position by name so the employer knows this letter is specific. Briefly reference a relevant project, class, or internship that connects you to the job.
4. Body Paragraph(s)
Use one short paragraph to describe your Swift experience, including a specific project or internship and the technologies you used, like UIKit, SwiftUI, or Combine. Follow with another paragraph that highlights soft skills such as problem solving and teamwork and ties those strengths to how you will add value in the role.
5. Closing Paragraph
Finish by reaffirming your interest and offering availability for an interview or a coding task to demonstrate your skills. Thank the reader for their time and express eagerness to discuss how you can contribute.
6. Signature
Close with a professional sign-off such as 'Sincerely' or 'Best regards' followed by your full name. Under your name, repeat your contact email and a link to your portfolio or GitHub for quick access.
Dos and Don'ts
Do keep each paragraph concise and focused on one main idea to make the letter easy to scan.
Do mention a specific Swift project, library, or course and explain what you contributed or learned from it.
Do match language from the job description when it reflects your real experience to help your application pass initial screenings.
Do show enthusiasm for the company by noting one thing you admire about their product, culture, or mission.
Do proofread carefully and ask a friend or mentor to read your letter for clarity and tone.
Don’t repeat your entire resume; instead, highlight two or three items that best show your fit for this role.
Don’t use vague claims like 'hard worker' without backing them up with a brief example or result.
Don’t include irrelevant personal information that does not relate to the job or your professional skills.
Don’t use overly technical jargon that might confuse a non-technical recruiter reviewing early-stage applications.
Don’t submit a generic cover letter to multiple companies without tailoring key details to each employer.
Common Mistakes to Avoid
Writing overly long paragraphs that cover multiple topics makes the letter hard to follow, so split ideas into short paragraphs. Keep paragraphs to two or three sentences each for readability.
Listing technologies without context does not show impact, so pair tools with outcomes or what you learned while using them. Focus on what you built and why it mattered.
Failing to address the company specifically gives the impression of a mass application, so add a brief, genuine detail about the company. Even one sentence of tailoring can improve your chances.
Neglecting soft skills can make you seem inexperienced in team settings, so include one example of collaboration or problem solving. Explain briefly how you worked with others or handled feedback.
Practical Writing Tips & Customization Guide
If you have a GitHub repo or App Store listing, link directly to the most relevant project and call out one feature you built. This helps the reader see your work without hunting for it.
Use active verbs and short sentences to keep energy in your letter and make your contributions clear. Prefer phrases like 'I built' or 'I improved' followed by the result.
When possible, quantify impact with simple metrics such as time saved or user feedback to make achievements concrete. Small numbers are fine and still helpful.
Keep a master template with placeholders for company name, role, and one tailored sentence to speed up customization without losing quality.
Cover Letter Examples
Example 1 — Recent Graduate (Entry-level iOS Developer)
Dear Ms.
I recently graduated with a B. S.
in Computer Science from UNC and built two iOS apps that are live on the App Store: a habit tracker with 12k downloads and a weather app that uses SwiftUI, Combine, and a REST API. In my capstone I reduced app launch time by 35% by profiling with Instruments and optimizing JSON parsing.
I completed an eight-week internship where I wrote unit tests with XCTest and merged 40+ pull requests using Git and GitHub flow.
I’m excited about the Junior iOS Developer role at BrightApps because your focus on UX aligns with my work improving retention by 18% through onboarding flows. I’m ready to contribute clean Swift code, help write tests, and ship features in two-week sprints.
Thank you for considering my application—I’d welcome the chance to discuss how my projects and internship experience can help your team deliver faster, polished releases.
Sincerely, Alex Chen
What makes this effective: Specific projects, measurable outcomes (12k downloads, 35% faster launch), and direct link to company goals.

Example 2 — Career Changer (Web to iOS)
Dear Hiring Manager,
After five years building customer-facing web apps with React and TypeScript, I transitioned to iOS development through a 16-week iOS bootcamp and three shipped apps. I rewrote a React feature that tracked user sessions and implemented the same analytics in Swift using URLSession and Codable, increasing event accuracy by 22% in my prototype.
I bring strong REST API design experience, proficiency with Git branching, and daily pair-programming practice.
At NovaHealth, I can apply my front-end performance mindset to reduce render stalls and help improve crash-free metrics; in my last role I cut JS load time by 40%. I’m comfortable translating product requirements into testable iOS components and mentoring junior teammates on best practices.
I look forward to discussing how my cross-platform background can speed feature delivery and improve user engagement on your mobile team.
Best regards, Maya Singh
What makes this effective: Highlights transferable skills, measurable improvements, and a clear reason for the career switch.

Example 3 — Experienced Professional (Early-career iOS Developer with 3 years)
Hello Mr.
Over the past three years as an iOS Engineer at Parkly, I led development on the booking module that handled 1M+ monthly requests and reduced payment failures by 14% after adding input validation and network retries. I maintain CI pipelines with Fastlane, write UI tests with XCUITest, and refactor legacy Objective-C into modular Swift packages.
I also mentored two junior engineers who later owned features end-to-end.
I’m drawn to BlueLine’s focus on scalable systems. I can quickly contribute by building reliable networking layers, improving telemetry to lower crash rates, and establishing PR review checklists to boost code quality.
I welcome the opportunity to review your codebase and propose a 30/60/90 plan to reduce app crashes by at least 10% in the first quarter.
Regards, Daniel Park
What makes this effective: Demonstrates ownership, concrete metrics (1M requests, 14% fewer failures), and a short plan aligned to company goals.
Writing Tips for an Effective Cover Letter
1. Lead with a specific achievement.
Start with one clear metric or result (e. g.
, “reduced app launch time by 35%”) to grab attention and show impact.
2. Match language to the job posting.
Mirror 2–3 key terms from the listing (SwiftUI, REST APIs, unit tests) to pass filters and signal fit.
3. Keep paragraphs short and purposeful.
Use 2–4 sentence paragraphs; each should show a skill, an example, and the outcome.
4. Show measurable results, not just duties.
Replace “built features” with “built a payment flow that cut failures by 14%”—numbers prove value.
5. Explain why the company matters to you.
Mention one product, metric, or team value and connect it to your experience so your interest feels specific.
6. Use active verbs and plain language.
Prefer “implemented,” “reduced,” or “mentored” over vague phrases; this makes contributions clear.
7. Address gaps proactively.
If you lack experience, cite a project, course, or bootcamp and one outcome (e. g.
, shipped 2 apps) to reduce concern.
8. End with a clear next step.
Propose a short call or offer to walk through a sample PR so hiring managers know how you’ll move the process forward.
9. Proofread for technical accuracy.
Verify frameworks, library names, and versions; a single error (e. g.
, mixing UIKit and SwiftUI terms incorrectly) undermines credibility.
How to Customize Your Cover Letter by Industry, Company Size, and Job Level
Strategy 1 — Tailor to the industry
- •Tech: Emphasize product metrics and tools. Mention frameworks (SwiftUI, Combine), testing (XCTest), CI/CD (Fastlane), and outcomes like “improved retention by 18%.” Show you care about user metrics and release cadence.
- •Finance: Stress reliability, security, and compliance. Note experience with encryption, secure network calls, or avoiding data leaks; cite latency or error-rate improvements (e.g., “cut API errors by 30%”).
- •Healthcare: Highlight privacy and accuracy. Reference HIPAA-awareness, data integrity checks, or clinical workflow experience and quantify accuracy or uptime where possible.
Strategy 2 — Adjust for company size
- •Startups: Focus on versatility and speed. Show that you can ship end-to-end (UI, networking, analytics) and give an example of a feature you built in <2 weeks or scaled to X users.
- •Corporations: Emphasize process and collaboration. Mention experience with code reviews, CI pipelines, and working in teams of 8+ across sprints; highlight how you improved a process (e.g., reduced merge conflicts by 25%).
Strategy 3 — Match the job level
- •Entry-level: Lead with projects, internships, and measurable outcomes (downloads, tests written). Offer to do a short coding task or walkthrough of a portfolio app.
- •Senior: Focus on ownership, mentoring, and systems thinking. Cite team metrics (onboarding time cut by 40%), architecture work (modularized codebase), and a 30/60/90 plan for your first three months.
Concrete customization tactics
1. Replace a generic sentence with one line about the target role: e.
g. , for a fintech role, swap “built network layers” with “built secure token refresh logic used by 200k users.
” 2. Use company data: reference a known metric (app store rating, downloads, funding round) and explain how you would impact it.
3. Mirror their tech stack from the job post and give 1–2 short examples of related work.
4. End with a role-specific next step: offer a 20-minute walkthrough of a relevant project or a short proposal to reduce a known pain point.
Actionable takeaway: Pick 2 industry-specific points, 1 company-size detail, and 1 level-appropriate example to swap into every base cover letter before sending.
