iOS / Swift Developer
iOS Developers write app-facing Swift code — building screens with SwiftUI or UIKit, wiring up Combine pipelines, and shipping through Xcode and App Store Connect. Their daily English covers describing optionals and closures in code review, writing App Store release notes, triaging crash logs, and explaining architecture choices like MVVM in standups. This path builds the vocabulary for day-to-day iOS app development, distinct from the infrastructure-level work of an iOS Platform Engineer.
Topics covered
- Swift language fundamentals
- SwiftUI & UIKit
- Xcode & build vocabulary
- App Store submission
- iOS architecture patterns
- Debugging & crash triage
Vocabulary spotlight
4 terms every iOS / Swift Developer should know in English:
A Swift type that represents either a value or the absence of one (nil), forcing explicit handling of missing data
"We unwrap the optional safely with `if let` instead of force-unwrapping it and risking a crash."
A self-contained block of functionality that can be passed around and executed later, capturing variables from its surrounding context
"The completion closure fires once the network request finishes, whether it succeeds or fails."
A file that links a signed app, a set of devices, and App Store entitlements, required to install or submit an iOS build
"The TestFlight build failed because the provisioning profile did not include the new push notification entitlement."
A memory leak caused by two objects holding strong references to each other, preventing either from being deallocated
"Using `[weak self]` in the closure broke the retain cycle between the view controller and its network manager."

Frequently Asked Questions
What English skills do iOS / Swift Developers most need to improve?+
iOS / Swift Developers most commonly need to improve: technical vocabulary (the correct English terms for domain concepts), collocation accuracy (using the right verb for each action), written communication (bug reports, PR descriptions, technical docs), and spoken communication for standups, code reviews, and stakeholder meetings.
How long does the iOS / Swift Developer learning path take?+
The iOS / Swift Developer learning path contains 20–40 hours of material studied comprehensively. Most learners focus on the highest-priority modules first and return to the rest over time. Spending 30 minutes per day for 4–6 weeks produces noticeable improvement in workplace English.
What vocabulary should a iOS / Swift Developer prioritise first?+
Start with the vocabulary that appears most in your daily work — terms you read in documentation, use in commit messages, and hear in meetings. The iOS / Swift Developer path begins with the most frequent vocabulary clusters before moving to advanced communication patterns.
Are there interview exercises for iOS / Swift Developer roles?+
Yes. The iOS / Swift Developer path includes role-specific interview question modules with model answers and key phrases — the actual questions interviewers ask and the vocabulary needed to answer them fluently. There is also a dedicated Interview Practice hub for general interview skills.
Does this path include pronunciation help?+
Yes. The path links to pronunciation exercises for the technical terms most commonly mispronounced in this domain. The Pronunciation hub includes drills for acronyms, silent letters, word stress, and minimal pairs — all in IT context.
What are the most common English mistakes iOS / Swift Developers make?+
The most common mistakes: incorrect collocations (using the wrong verb with a technical noun), false friends from L1, tense errors when narrating past incidents or walkthroughs, and using overly formal or overly casual register in written communication.
How do I improve my English for code reviews?+
Learn the standard code review collocations: approve a PR, request changes, leave a nit, address feedback, block a merge, resolve a conversation. Use hedging language for suggestions: "This might be cleaner as…", "Have you considered…?". The Collocations section includes a dedicated Code Review set.
Can I use this path alongside my daily work?+
Yes — the path is designed for working professionals. Each exercise set takes 10–15 minutes. The most effective approach is to study a vocabulary module before a meeting or task where you'll use that vocabulary, then practise immediately after. Context-linked practice produces much faster retention.
Is the content free?+
Yes, completely free. No registration required, no payment, no time limit. All vocabulary modules, exercises, glossary entries, and learning path guides are open access.
How do I track my progress through this path?+
Progress is tracked in your browser's local storage — completed exercise sets are marked with a checkmark when you return. No account is needed. You can bookmark specific modules and use the exercises overview to see which sets you've completed.
