tvos-patterns

A collection of SwiftUI patterns for tvOS apps, covering Siri Remote input, video playback, and the Top Shelf home-screen extension.

In plain words
What is it for?
Use it to handle directional movement, play/pause and back commands, long presses, AVKit video playback, and Top Shelf content.
Why use it?
It explains interaction patterns for television screens, where users navigate by focus and remote buttons rather than touch or a mouse.

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.

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

tvos-patterns 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 2d 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.

tvOS Platform Patterns

Siri Remote Input

tvOS uses the Siri Remote — all interaction is through focus and button presses:

// Handle directional movement
.onMoveCommand { direction in
    switch direction {
    case .up: moveUp()
    case .down: moveDown()
    case .left: moveLeft()
    case .right: moveRight()
    @unknown default: break
    }
}

// Handle Play/Pause button
.onPlayPauseCommand {
    togglePlayback()
}

// Handle Menu/Back button
.onExitCommand {
    dismiss()
}

// Long press on select button
.onLongPressGesture {
    showOptions()
}

Media Playback (AVKit)

import AVKit

struct PlayerView: View {
    let url: URL
    @State private var player: AVPlayer?

    var body: some View {
        VideoPlayer(player: player)
            .onAppear {
                player = AVPlayer(url: url)
                player?.play()
            }
            .onDisappear {
                player?.pause()
            }
            .ignoresSafeArea()
    }
}

Top Shelf Extension

The only supported extension type on tvOS — shows content on the home screen:

// In Targets/TopShelf/ContentProvider.swift
import TVServices

struct TopShelfProvider: TVTopShelfProvider {
    var topShelfStyle: TVTopShelfContentStyle { .sectioned }

    var topShelfItems: [TVTopShelfSectionedItem] {
        let section = TVTopShelfItemCollection(items: [
            makeItem(id: "1", title: "Featured Movie", imageURL: url1),
            makeItem(id: "2", title: "New Release", imageURL: url2),
        ])
        section.title = "Featured"
        return [section]
    }

    func makeItem(id: String, title: String, imageURL: URL) -> TVTopShelfSectionedItem {
        let item = TVTopShelfSectionedItem(identifier: id)
        item.title = title
        item.setImageURL(imageURL, for: .screenScale1x)
        item.displayAction = TVTopShelfAction(url: URL(string: "myapp://item/\(id)")!)
        return item
    }
}

Parallax Effect (Focus Art)

tvOS automatically applies parallax effects to images in focused buttons:

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.

tvos-patterns is a skill published in the GitHub repository Abdullah4AI/apple-developer-toolkit (10 stars, last pushed 5d ago), licensed MIT. It adds 74 tokens to every session and 1,241 once invoked, about $0.0004 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 2026-08-31.
