maui safe-area-ios.instructions.md

maui safe-area-ios.instructions.md is an instructions file for GitHub Copilot from dotnet/maui. It costs 483 tokens per session, scanned A, original, MIT.

Development guidance for handling safe areas in .NET MAUI apps on iOS and macOS Catalyst. Safe areas are screen regions reserved for system elements such as a notch or title bar.

In plain words
What is it for?
Applying edge-specific safe-area adjustments, checking parent views, comparing insets reliably, and accounting for iOS and macOS platform differences.
Why use it?
It helps prevent content from being covered, padded twice, or behaving differently in local tests and continuous integration.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

maui safe-area-ios.instructions.md 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 4d 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.

What it actually says

Safe Area Guidelines (iOS/macCatalyst)

Platform Differences

macOS 14/15 macOS 26+
Title bar inset ~28px ~0px
Used in CI

Local macOS 26+ testing does NOT validate CI behavior. Fixes must pass CI on macOS 14/15.

Platform UseSafeArea default
iOS false
macCatalyst true

Architecture (PR #34024)

IsParentHandlingSafeArea — before applying adjustments, MauiView/MauiScrollView walk ancestors to check if any ancestor handles the same edges. If so, descendant skips (avoids double-padding). Edge-aware: parent handling Top does not block child handling Bottom. Result cached in bool? _parentHandlesSafeArea; cleared on SafeAreaInsetsDidChange, InvalidateSafeArea, MovedToWindow. AppliesSafeAreaAdjustments is internal for cross-type ancestor checks.

EqualsAtPixelLevel — safe area compared at device-pixel resolution to absorb sub-pixel animation noise (0.0000001pt during TranslateToAsync), preventing oscillation loops (#32586, #33934).

Anti-Patterns

❌ Window Guard — comparing Window.SafeAreaInsets to filter callbacks blocks legitimate updates. On macCatalyst + custom TitleBar, WindowViewController pushes content down, changing the view's SafeAreaInsets without changing the window's. Caused 28px CI shift (macOS 14/15 only). Never gate per-view callbacks on window-level insets.

❌ Semantic mismatch_safeArea is filtered by GetSafeAreaForEdge (zeroes edges per SafeAreaRegions); raw UIView.SafeAreaInsets includes all edges. Never compare them — compare raw-to-raw or adjusted-to-adjusted.

Changes

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.
