Assets & App Icons


Assets & App Icons

Manage images, colors, and icons in Assets catalogs, and prepare required app icon sizes for submission.


Assets Catalog

Use Assets.xcassets to manage images, colors, and app icons.

Checklist

  • AppIcon set with required sizes for iPhone/iPad
  • AccentColor for your app
  • Image sets in 1x/2x/3x

Assets catalogs help you organize and optimize your app's visual assets, making it easier to maintain and update your app's appearance.


System Symbols

Use SF Symbols to add system-like icons to your app.

Example

import SwiftUI

struct SymbolsDemo: View {
  var body: some View {
    HStack(spacing: 24) {
      Image(systemName: "star.fill")
        .font(.system(size: 40))
        .foregroundStyle(.yellow)
      Image(systemName: "heart.fill")
        .font(.system(size: 40))
        .foregroundStyle(.red)
      Image(systemName: "bolt.fill")
        .font(.system(size: 40))
        .foregroundStyle(.blue)
    }
    .padding()
  }
}
import SwiftUI

struct ContentView: View {
  var body: some View { SymbolsDemo() }
}
import SwiftUI

@main
struct MyApp: App {
  var body: some Scene {
    WindowGroup { ContentView() }
  }
}

App Icon Guidelines

Keep icons simple and recognizable.

Avoid transparency.

Follow Apple's Human Interface Guidelines.

Tip: Use SF Symbols for consistent system-like icons where possible.
