iOS Development Reference

Generic iOS guidance retained as background reading. This is not repo-specific. For anything concerning this SDK, the authoritative sources are AGENTS.md, docs/migration/playbook.md, and the runbooks in agents/ — see the routing table in AGENTS.md. Migration material lives in its own skill, agents/migration-patterns/.

Much of the original third-party bundle was removed as inapplicable: this is a header-bidding ad SDK (a UIKit library, iOS 13+), not an app. It has no SwiftUI, no Core Data, no navigation hierarchy, no App Store presence. What remains below is the subset with some bearing on the code.

Available modules

coding-best-practices/

• swift-patterns.md — Swift idioms: optionals, type safety, collections, error handling. Its naming section reflects this repo's no-single-letter-names rule.
• architecture-patterns.md — largely MVVM/app-oriented, so mostly inapplicable to a library. The memory-management notes and "don't log sensitive data" are the relevant parts; the latter matters here given consent strings, IDFA, and EIDs.

ui-review/

Written in SwiftUI idiom, so the mechanisms rarely transfer — but the thresholds are format-neutral and do apply to the ad chrome this SDK draws over advertiser content.

• hig-checklist.md — notably the 44×44pt minimum tap target, and the orientation matrix.
• accessibility-quick-ref.md — contrast ratios (4.5:1 text, 3:1 UI components) and the VoiceOver / Dynamic Type / Reduce Transparency test matrix.
• font-guidelines.md — the fixed-point-size anti-pattern applies to the two places the SDK draws text; every remedy in the file is SwiftUI, so translate to UIFontMetrics yourself.

ipad-patterns/

• multitasking.md — size-class and trait-change handling, plus the UIScreen.main.bounds anti-pattern. Relevant because the SDK renders inside a host app's window, which may be a fraction of the screen under Split View or Stage Manager.

How to use

Read a specific file when its topic comes up. Prefer repo-specific docs wherever both cover the same ground — these files cannot know this codebase's constraints.
