📝 Walkthrough

Walkthrough

This PR introduces a new tauri-plugin-ios-keyboard plugin for iOS, transitioning from an external crate dependency to a local path-based implementation. It includes comprehensive Swift and Rust plugin scaffolding, keyboard event detection and observation, and permission configuration files for iOS keyboard integration.

Changes

Cohort / File(s)	Summary
Cargo.toml Root Dependency src-tauri/Cargo.toml	Updated iOS keyboard plugin dependency from crates.io version pin to local path (plugins/ios-keyboard).
Tauri iOS API Scaffolding src-tauri/plugins/ios-keyboard/.tauri/tauri-api/*	Establishes foundational Swift interop layer with Package.swift manifest, JSON/JS type abstractions (JSTypes, JsonValue), channel and invoke handling, logging redirection, plugin base class, and UI utilities for iOS Tauri plugins.
iOS Keyboard Plugin Rust src-tauri/plugins/ios-keyboard/Cargo.toml, build.rs, src/*	Implements Rust plugin layer with command handling (ping), platform-specific desktop/mobile initialization, error types, and data models; sets up build toolchain for Tauri plugin generation.
iOS Keyboard Plugin Swift Implementation src-tauri/plugins/ios-keyboard/ios/Package.swift, Sources/KeyboardPlugin.swift, Package.resolved	Provides native iOS keyboard event observation via UIResponder notifications, forwards keyboard show/hide events to JavaScript, and coordinates webview scroll behavior with keyboard state.
iOS Keyboard Permissions & Configuration src-tauri/plugins/ios-keyboard/permissions/*	Defines permission schema (JSON Schema, permission sets, autogenerated command permissions for ping) and documentation table.
Frontend Adjustments src/hooks/useKeyboardResize.ts, src/index.css	Removes redundant iOS keyboard mutation of overscrollBehavior; adds global CSS rule to suppress document scroll and overscroll behavior on HTML element.

Poem

🐰 Hop along the iOS shore,
Keyboard events we now adore!
Swift and Rust in harmony blend,
From UIResponder to JavaScript end!
The plugin path now local, no more delay—
A rabbit's touch makes keyboards play! 🎹
