Adaptivity (C) vs Accessibility Techniques

Adaptivity is an invaluable tool for developers and designers. Use it to visualize how Size Classes and margins for layout, readable content and the safe area look on real devices and how they change with respect to orientation and Dynamic Type size changes. This free version has reduced features. TESTIMONIALS • “Adaptivity is not just highly recommended – it’s essential” — Paul Hudson, Hacking With Swift article “8 essential apps for iOS developers”, 30th March 2020. • “It's a very, very good tool as a reference for both developers and designers” — Gui Rambo, Stacktrace podcast episode #77, 1st April 2020. • “I'm not trying to spend your money, but to me this is a no-brainer” — Sean Allen YouTube video “Indie Dev Apps”, 12th April 2020. MAIN FEATURES • Only supports iPhone to visualize how an iPhone‑only app appears on iPad. • Visualize sizes for full view, layout margins, readable content guide and safe area layout guide. • Sizes displayed in points or pixels. • Regular or large navigation bar titles. • Toggle status bar and navigation bar/toolbar/tab bar visibility. • Activity View Controller for sharing a snapshot image of each view. • Dark appearance support (requires iOS/iPadOS 13 or later). • Setting to force right-to-left layout. • Handoff actions from Adaptivity (C) on one device to Adaptivity (A) on another.

Adaptivity (C) has the same reduced features as Adaptivity (B) but only supports iPhone. Use it to visualize how an iPhone‑only app appears on iPad.

Learn how to build accessible iOS apps by seeing the same component done right and done wrong, side by side. Accessibility Techniques is a working reference of 89 SwiftUI techniques. Every one ships a good and a bad example you can test yourself with VoiceOver turned on, so you hear the difference a proper accessibility label makes and what breaks when focus is not managed. Each technique maps to the WCAG 2.2 success criteria it satisfies. What's inside • 89 techniques in a searchable, alphabetical index • Good and bad examples side by side, each with a Details note explaining exactly why it passes or fails • Coverage of VoiceOver, Voice Control, Dynamic Type, Dark Mode, Reduce Motion, Increase Contrast, Smart Invert, and more • Written documentation for every technique, linked to the relevant WCAG criteria and Apple's developer docs • A companion watchOS app Who it's for Developers, designers, and QA who need to settle a question quickly, verify a real VoiceOver announcement before shipping, or show a teammate why a pattern fails. Open source The full SwiftUI source is on GitHub, so you can read how each example is built and copy what you need. The project also includes a11y-check, a free static analysis tool that scans your own Swift code for accessibility issues — 43 rules across 23 WCAG 2.2 criteria. https://github.com/cvs-health/ios-swiftui-accessibility-techniques Issues, suggestions, and contributions welcome.
