WWDC 2026 ハイライト：2年遅れの Siri 刷新、iOS 27 スノーレパード戦略、年10億ドル Gemini
WWDC 2026 で Apple は WWDC 2024 の「新 Siri」約束をようやく提出。2025 年 3 月の延期と 2026 年 1 月の Google Gemini 提携の後、6 月キーノートで Siri AI が iOS 27 の中心に（東京ノード）。

1. Siri：2 年遅れの提出
2026 年に遅延の余地はなく—独立 Siri AI が製品回答。
1) Standalone Siri app
Per Bloomberg’s Mark Gurman and WWDC live coverage, Siri becomes a dedicated app on iPhone, iPad, and Mac—iMessage-style threads, persistent history, and iCloud sync so you can start on iPhone and continue on Mac. Users may review past chats and upload files for analysis.
Product-form shift: Siri moves from a transient overlay to a daily-open app. See our Siri AI 詳解 for post-keynote architecture.
2) Personal data integration
Gurman reports a Gemini-based Siri with system-level permissions across iOS 27, iPadOS 27, and macOS 27 Golden Gate—messages, photos, calendar, and documents. This is the on-screen, cross-app Siri Apple promised at WWDC 2024 but delayed in March 2025.
Quotable: The moat is not parameter count—it is permissioned access to on-device personal context.
3) Interaction redesign
The full-screen rainbow border is gone. Siri lives in the Dynamic Island; you still say “Siri” or long-press the side button, but animations anchor at the top. New gesture: swipe down from the top-center on iOS 27 for a unified search-or-ask sheet with typing and voice.
Years of bottom-sheet muscle memory will need retraining—but top-anchored assistants match Island-first hardware.
4) Pick your AI engine
Multiple reports say iOS 27, iPadOS 27, and macOS 27 Golden Gate let users choose the model behind Apple Intelligence—Apple models, Google Gemini, Anthropic Claude, or OpenAI ChatGPT. If true, it is Apple’s most open AI architecture ever for a company built on walled gardens.
Developers should plan disclosure strings and fallbacks per provider—see Gemini ガイド.
5) The $1B/year Gemini line item
Bloomberg cites roughly $1 billion/year for a custom 1.2 trillion-parameter Gemini driving the rebuilt Siri. The number signals urgency: Apple is buying scale instead of waiting on an in-house frontier trainer.
2. iOS 27：スノーレパード戦略
iOS 27 は品質・性能重視（MacRumors/Bloomberg 等）。レガシー整理と Liquid Glass 調整。
透明度・コントラストスライダーでガラス強度をユーザー調整可能に。
3. カメラと写真：オンデバイス生成 AI
写真アプリに 3 つのオンデバイスツール：
| Tool | What it does | Ship note |
|---|---|---|
| Extend | Generative fill to expand frame content | On-device |
| Enhance | One-tap cleanup for quality, light, color | On-device; may ship trimmed |
| Reframe | Adjust spatial photo viewpoint after capture | On-device; beta risk |
Enhance/Reframe は内測難航の報道。カメラ詳細タブで深度・露出・手動/プリセット・ヒストグラム。
4. macOS 27 Golden Gate：Intel 終了
Intel Mac サポート終了—M 系統一後の最適化。Intel ユーザーは 2026 秋前に移行を。

5. ハードウェア：最大 9 機種の噂
| Rumor device | Reported spec | WWDC note |
|---|---|---|
| Apple TV 4K | A17 Pro, N1 chip, Wi‑Fi 7, HDMI passthrough | Strongest leak; Siri-ready local |
| HomePod Pad | HomePod + iPad-style display | vs Nest Hub / Echo Show |
| M5 Mac wave | Multiple Mac refreshes | Tied to supply timelines |
| Face ID camera | First Apple security cam | Smart home stack |
| Siri gate | TV/HomePod ready months | Waiting on Siri AI readiness |
Apple TV/HomePod は Siri AI 待ちの報道。
6. 折りたたみ iPhone：ソフトの布石
WWDC で折りたたみ実機は非公開—2026 年下半期が有力。iOS 27 SDK の UIKit/SwiftUI 適応レイアウトを確認。
ベータで Size Class をテスト。
推奨
- アプリ開発： beta 導入、EU フォールバック、Mac なし。
- Siri 追跡： Siri AI → Gemini。
- Intel Mac： 秋前に移行。
- HW： 噂はメニュー、確定は keynote。
FAQ
Why was Siri delayed from WWDC 2024?
Apple postponed personal-context Siri features in March 2025, then partnered with Google on Gemini in January 2026 before shipping Siri AI at WWDC 2026.
What changed in the standalone Siri app?
Per Gurman and keynote coverage: dedicated app, iMessage-style threads, iCloud sync across iPhone/iPad/Mac, file uploads.
Is iOS 27 a big feature release?
Reporting frames iOS 27 as a Snow Leopard-style polish release—performance, legacy cleanup, and Liquid Glass sliders—not a visual revolution.
Does macOS 27 still support Intel Macs?
No—macOS 27 Golden Gate ends Intel support; plan Apple-silicon hardware before Fall 2026 GA.
Will foldable iPhone appear at WWDC?
Unlikely—Gurman and Kuo point to H2 2026 hardware; iOS 27 SDK may add fold-adaptive APIs first.
