- Manage Xcode project assets including app icons, images, and asset catalogs. Use when handling app icon installation, image asset creation, or asset catalog modifications.
Asset Management
Asset Catalog Structure
Xcode projects use .xcassets bundles containing named asset sets:
Assets.xcassets/
Contents.json # Root catalog manifest
AppIcon.appiconset/
Contents.json # Icon set manifest with image references
AppIcon.png # The actual icon file
AccentColor.colorset/
Contents.json # Color set manifest
App Icon Requirements by Platform
All platforms require a single high-resolution icon. Xcode generates all needed sizes automatically.
| Platform | Size | Idiom | Platform Key | |----------|------|-------|-------------| | iOS | 1024x1024 | universal | ios | | watchOS | 1024x1024 | universal | watchos | | tvOS | 1280x768 | tv | tvos | | macOS | 1024x1024 | mac | (none) | | visionOS | 1024x1024 | universal | xros |
Contents.json Format
iOS example:
{
"images": [
{
"filename": "AppIcon.png",
"idiom": "universal",
"platform": "ios",
"size": "1024x1024"
}
],
"info": {
"version": 1,
"author": "xcode"
}
}
macOS uses "idiom": "mac" with "scale": "1x" and no "platform" key.
Image Processing with sips
macOS includes sips (scriptable image processing system) for image manipulation:
# Query dimensions
sips -g pixelWidth -g pixelHeight image.png
# Resize to exact dimensions
sips -z 1024 1024 image.png
# Convert format to PNG
sips --setProperty format png image.jpg --out image.png
# Resize and convert in one step
sips -z 1024 1024 --setProperty format png input.jpg --out output.png
Verifying Icon Installation
To verify an icon is correctly installed:
- Check
AppIcon.appiconset/Contents.jsonhas afilenameentry - Verify the referenced file exists in the same directory
- Confirm dimensions match the platform requirement using
sips -g pixelWidth -g pixelHeight - Build the project to verify Xcode accepts the icon
Finding the Asset Catalog
Search for the asset catalog in the project:
find . -name "AppIcon.appiconset" -not -path "*/DerivedData/*" -not -path "*/.build/*"
Or use Glob: **/AppIcon.appiconset/

Apple platform skill for docs, WWDC lookup, App Store Connect work, and SwiftUI app generation. Use repo-local `node cli.js` for Apple docs and WWDC search, `appledev store` for App Store Connect workflows, and `appledev build` for app scaffolding or fix loops on macOS. USE WHEN: Apple APIs, WWDC sessions, TestFlight/App Store tasks, or building/fixing Apple-platform apps. DON'T USE WHEN: non-Apple platforms, generic backend work, or general web research. EDGE CASES: docs-only queries use `node cli.js` in this repo, not `appledev`; release workflows use `appledev store`; app scaffolding uses `appledev build`; rules-only requests can read `references/ios-rules/` or `references/swiftui-guides/` progressively without invoking binaries.

All-in-one Apple developer skill with three integrated tools shipped as a single unified binary. (1) Documentation search across Apple frameworks, symbols, and 1,267 WWDC sessions from 2014-2025. No credentials needed. (2) App Store Connect CLI with 120+ commands covering builds (find/wait/upload), TestFlight, pre-submission validate, submissions, signing, subscriptions (family-sharable), IAP, analytics, Xcode Cloud, metadata workflows, release pipeline dashboard, insights, win-back offers, promoted purchases, product pages, nominations, accessibility declarations, pre-orders, pricing filters, localizations update, diff, webhooks with local receiver, workflow automation, and more. Requires App Store Connect API key. (3) Multi-platform app builder (iOS/watchOS/tvOS/iPad/macOS/visionOS) that generates complete Swift/SwiftUI apps from natural language with auto-fix, simulator launch, interactive chat mode, and open-in-Xcode. Requires an LLM API key and Xcode. Includes 38 iOS development rules and 12 SwiftUI best practice guides for Liquid Glass, navigation, state management, and modern APIs. All three tools ship as one binary (appledev). USE WHEN: Apple API docs, App Store Connect management, WWDC lookup, or building iOS/watchOS/tvOS/macOS/visionOS apps from scratch. DON'T USE WHEN: non-Apple platforms or general coding.
