Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.00749 |
| Opus 5 | $0.00024 | $0.00375 |
| Sonnet 5 | $0.00010 | $0.00150 |
| Haiku 4.5 | $0.00005 | $0.00075 |
Grade A, and why
ios-26-platform scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS 26 Platform
iOS 26 introduces Liquid Glass, Apple's next-generation material design system that dynamically bends light, moves organically, and adapts automatically across all platforms.
Overview
iOS 26 modernizes UI with new materials (Liquid Glass), SwiftUI APIs (WebView, Chart3D, @Animatable), and advanced features (@BackoffAnimation, free-form windows). The core principle: modern UI gets updated automatically at compile time; most Liquid Glass benefits are "free" from recompiling with Xcode 26.
Reference Loading Guide
ALWAYS load reference files if there is even a small chance the content may be required. It's better to have the context than to miss a pattern or make a mistake.
| Reference | Load When |
|---|---|
| Liquid Glass | Implementing glass effects, choosing Regular vs Clear variants, or understanding visual properties |
| Automatic Adoption | Understanding what iOS 26 changes automatically vs what requires code |
| SwiftUI APIs | Using WebView, Chart3D, @Animatable, AttributedString, or new view modifiers |
| Toolbar & Navigation | Customizing toolbars with spacers, morphing, glass button styles, or search |
| Backward Compatibility | Supporting iOS 17/18 alongside iOS 26, or using UIDesignRequiresCompatibility |
Core Workflow
- Check deployment target — iOS 26+ required for Liquid Glass
- Recompile with Xcode 26 — Standard controls get glass automatically
- Identify navigation layer — Apply glass to tab bars, toolbars, navigation (not content)
- Choose variant — Regular (95% of cases) or Clear (media-rich backgrounds only)
- Add @available guards — For backward compatibility with iOS 17/18
- Test accessibility — Verify Reduce Transparency, Increase Contrast, Reduce Motion
Common Mistakes
- Ignoring backward compatibility — Targeting iOS 26+ without
@availableguards breaks iOS 17/18 support. Always useif #available(iOS 26, *)for Liquid Glass or new APIs.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ios-26-platform is a skill published in the GitHub repository johnrogers/claude-swift-engineering (228 stars, last pushed 7mo ago), licensed MIT. It adds 49 tokens to every session and 749 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
