這條通知背後是 iOS 27 家長控制的一環：Apple 想讓家長能針對「社群類 app」單獨設時間額度。所以它需要每個 app 自己申報「有沒有社群功能」。對開發者來說這不是要你改 code，是問卷多了一組必答題——但答錯會讓兒童 app 平白拿到 13+ 分級，值得先搞懂定義。
This notice is part of iOS 27 parental controls: Apple wants parents to set separate time allowances for "social media" apps, so every app must now declare whether it has social media capabilities. It's not a code change — just a new mandatory questionnaire section. But answering wrong can hand a kids' app an unwarranted 13+ rating, so the definition is worth getting right.
先看定義：Apple 說的「社群功能」是什麼
The Definition: What Apple Means by "Social Media"
Apple 的定義很窄，關鍵字是 UGC + 動態牆：
Apple's definition is narrow. The keywords are UGC + a feed:
「能透過社群動態牆或類似的探索方式，去轉發、擴散或互動使用者產生的內容（UGC）的能力。」
"The ability to redistribute, amplify, or interact with user-generated content through a social feed or similar discovery method."
符合的 app 會在商店頁多一個「Social Media」內容標籤，並被歸進 iOS/iPadOS/macOS 27 的社群時間額度分類（與你在 ASC 選的 app 類別無關，純看功能）。
Matching apps get a new "Social Media" content descriptor on their product page and fall into the iOS/iPadOS/macOS 27 Social Media time-allowance category — independent of the app category you picked in ASC; it's purely about the capability.
時間軸與一個關鍵例外
Timeline and One Key Exception
💡 13 歲以下例外
💡 The under-13 exception
：就算你的 app 有社群功能，只要申報「13 歲以下停用」，13 歲以下用戶就不會被列進社群時間額度、也不會被強制拉到 13+。這代表兒童 app 加多人／社交功能，並不必然要吃 13+ 分級——前提是對未成年關掉社交能力。
: Even if your app has social capabilities, declaring them "disabled for under-13" keeps those users out of the social time-allowance category and off the forced 13+ rating. So a kids' app can include multiplayer/social features without automatically taking a 13+ rating — as long as the social bits are off for minors.
核心問題：Game Center 回合制連線對戰算社群媒體嗎？
The Core Question: Does Game Center Turn-Based Multiplayer Count?
不算。回到定義就清楚了。
No — go back to the definition.
社群功能的判準是「動態牆 + 轉發/擴散 UGC」。兩個人透過 Game Center 下同一盤棋，交換的是棋步座標，不是可以被別人瀏覽、按讚、轉發的貼文。沒有動態牆、沒有內容探索、沒有 UGC——所以年齡分級的社群題答 No。
The test is "a feed that redistributes/amplifies UGC." Two people playing one board over Game Center exchange move coordinates, not posts others can browse, like, or reshare. No feed, no content discovery, no UGC — so you answer No to the social media questions.
我自己的例子：五子棋小學堂新版走 Game Center 回合制親友對戰（邀請制、非陌生人隨機配對），維持兒童分級，社群題照樣答 No。
My own case: the new Gomoku Kids uses Game Center turn-based family matches (invite-only, no random stranger matchmaking). It keeps its kids rating and still answers No.
📋 順手釐清：什麼才要答 Yes
📋 So what does answer Yes?
：公開留言牆、用戶互看的貼文動態、可被陌生人瀏覽的個人檔案內容——這些才是社群。單純分享成績截圖到系統分享面板、純數字排行榜，通常都不算。判準永遠回到「有沒有一個讓 UGC 被別人看見/擴散的動態牆」。
: A public comment wall, browsable user posts, profile content strangers can view — those are social. Sharing a score screenshot via the system share sheet, or a plain numeric leaderboard, generally is not. Always come back to "is there a feed where UGC gets seen/amplified by others."
真正該小心的，其實不是這題——是 Kids Category 規則
The Real Thing to Watch Isn't This Question — It's the Kids Category Rules
社群分級題答 No 很容易；但如果你在兒童 app 裡加連線對戰，Guideline 1.3（Kids Category）有自己一套要求，這才是送審會被退的地方：
Answering No is easy. But if you add multiplayer to a kids' app, Guideline 1.3 (Kids Category) has its own requirements — that's where review actually rejects you:
🔴 最快被退的一件事：自由文字聊天
🔴 The fastest rejection: free-text chat
。玩家之間能打字聊天，是兒童 app 幾乎必退的功能。只傳「落子座標」、不開任何自由輸入的溝通管道，是最安全的設計。
. Letting players type to each other is a near-guaranteed rejection for kids' apps. Exchange only move data, with no free-text channel — that's the safe design.
- 優雅降級（最容易漏測）：未成年 Game Center 帳號會被家長在「螢幕使用時間 → 內容與隱私 → 多人遊戲 / 加朋友」關掉。當
GKLocalPlayer 驗證失敗或多人被停用時，app 要顯示清楚訊息、而不是卡死或 crash。用真實兒童帳號測這條。
- Graceful degradation (most-missed test): a child's Game Center account can be disabled by parents under Screen Time → Content & Privacy → Multiplayer Games / Adding Friends. When
GKLocalPlayer auth fails or multiplayer is off, show a clear message — don't hang or crash. Test with a real child account.
- 加好友 / 邀請流程考慮 parental gate：純 Game Center 系統邀請面板由 Apple 管、通常可接受；但自己做的加好友或跨 app 社交入口，考慮擋在家長驗證（一道算術題）後面。
- Gate friend/invite flows: the native Game Center invite sheet is Apple-managed and generally fine; but any custom add-friend or cross-app social entry point should sit behind a parental gate (a math question).
- 隱私標籤複查：Game Center 配對會把 player ID 交給 Apple（不是交給你），一般仍可維持「開發者不收集資料」，但送審時 App Privacy 那欄的描述要跟實際一致。
- Recheck the privacy label: Game Center matchmaking hands the player ID to Apple (not to you), so "developer collects no data" usually still holds — but make sure the App Privacy section matches reality at submission.
- 回合制優於即時制：
GKTurnBasedMatch 不需雙方同時在線，攻擊面更小、也更適合祖孫慢慢下。能用回合制就別上即時語音/連線。
- Prefer turn-based over real-time:
GKTurnBasedMatch needs no simultaneous presence, has a smaller attack surface, and suits slow family play. Use it instead of real-time voice/session where you can.
現在該做什麼（給獨立開發者的行動清單）
What to Do Now (Indie Dev Action List)
1. 九月前先填。雖然七月只是「自願」，但九月起送任何更新都必答。與其等到補件重送當下被卡，不如現在就進每個 app 的 App Information 把社群題填好。
1. Fill it in before September. July is "voluntary," but from September every submission requires it. Rather than get blocked mid-resubmission, go into each app's App Information now and answer the social questions.
2. 純單機／教育類兒童 app 一律 No。沒有動態牆就是沒有社群功能，誠實答 No，對兒童 app 反而是信任加分。
2. Single-player / educational kids' apps answer No. No feed means no social capability — answering No is honest and reads as a trust signal for kids' apps.
3. 有連線對戰的，重點放在 Kids Category 送審實測，不是這題。用真實兒童帳號跑一遍：關掉多人遊戲測降級、確認沒有任何自由聊天入口、隱私標籤描述一致。
3. If you have multiplayer, focus on Kids Category testing, not this question. Run it on a real child account: test degradation with multiplayer off, confirm zero free-text chat entry points, verify the privacy label is consistent.
一句話：年齡分級新增的社群題，對沒有動態牆的兒童 app 就是「答 No、九月前先填」，不用改任何 code；真正要投時間的是——如果你有連線對戰，去測「家長把多人遊戲關掉時，你的 app 會不會優雅降級」。
In one line: for feed-less kids' apps, the new social questions mean "answer No, fill it in before September" — no code change. The time actually worth spending: if you have multiplayer, test whether your app degrades gracefully when a parent turns multiplayer off.
