Platform Notes

• Optional helper plugins may help in some environments, but they must not be treated as required for this skill.

iOS Development Standards

<!-- dual-compat-start -->

Use When

• iOS development standards for AI agent implementation. Swift-first, SwiftUI, MVVM + Clean Architecture, async/await, comprehensive security, testing, and performance patterns. Use when building or reviewing iOS applications, generating Swift...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to ios-development or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve; load references only as needed.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.

Workflow

• Read this SKILL.md first, then load only the referenced deep-dive files that are necessary for the task.
• Apply the ordered guidance, checklists, and decision rules in this skill instead of cherry-picking isolated snippets.
• Produce the deliverable with assumptions, risks, and follow-up work made explicit when they matter.

Quality Standards

• Keep outputs execution-oriented, concise, and aligned with the repository's baseline engineering standards.
• Preserve compatibility with existing project conventions unless the skill explicitly requires a stronger standard.
• Prefer deterministic, reviewable steps over vague advice or tool-specific magic.

Anti-Patterns

• Treating examples as copy-paste truth without checking fit, constraints, or failure modes.
• Loading every reference file by default instead of using progressive disclosure.

Outputs

• A concrete result that fits the task: implementation guidance, review findings, architecture decisions, templates, or generated artifacts.
• Clear assumptions, tradeoffs, or unresolved gaps when the task cannot be completed from available context alone.
• References used, companion skills, or follow-up actions when they materially improve execution.

References

• Use the references/ directory for deep detail after reading the core workflow below.

Load Order

1. Load world-class-engineering for shared production gates.
2. Load system-architecture-design when the app participates in broader service or module architecture.
3. Load this skill for iOS implementation details.
4. Load ios-app-security, ios-networking-advanced, or other focused skills as needed.

Production-grade iOS development standards for AI-assisted implementation. Swift-first with SwiftUI, following modern Apple platform best practices.

Core Stack: Swift 6.0+ | SwiftUI (default UI) | MVVM + Clean Architecture | Swift Concurrency Min Deployment: iOS 17+ | IDE: Xcode 16+ Compatibility: Must run flawlessly on both the minimum deployment target AND the latest iOS release Reference App: Apple's sample code gallery and WWDC sessions — canonical examples of modern SwiftUI patterns

Backend Environments

iOS apps connect to a PHP/MySQL backend deployed across three environments:

| Environment | Base URL Pattern | Database | Notes | |---|---|---|---| | Development | http://{LAN_IP}:{port}/DMS_web/api/ | MySQL 8.4.7 (Windows WAMP) | Use host machine LAN IP | | Staging | https://staging.{domain}/api/ | MySQL 8.x (Ubuntu VPS) | For QA and TestFlight | | Production | https://{domain}/api/ | MySQL 8.x (Debian VPS) | App Store release |

Configure base URLs using Xcode build configurations and .xcconfig files so each scheme targets the correct backend. All backends use utf8mb4_unicode_ci collation and MySQL 8.x.

Additional Guidance

Extended guidance for ios-development was moved to references/skill-deep-dive.md to keep this entrypoint compact and fast to load.

Use that deep dive for:

• Swift Language Standards
• Architecture: MVVM + Clean Architecture
• Project Structure
• State Management (iOS 17+ — No Legacy Patterns)
• Networking Layer
• Build Configuration (3 Environments)
• Security Standards
• Testing Strategy
• Performance Rules
• Release Gate
• Navigation (iOS 17+)
• Minimum Requirements
• Additional deep-dive sections continue in the reference file.
