アップルがiPhoneソフト開発に使ってるのと全く同じAPIとツールが入ったソフトウェア開発キット（SDK）が、いよいよ公開になりましたね。
と言っても、このSDKで作った新しいアプリ君たちがiPod touchをお使いの日本の皆さまのお手元に届くのは6月のアップデートの時。しかもiPhoneはアップデートが無料なのにtouchの皆さまは有料で、アメリカでは｢なんで～｣の声がさっそく沸き起こってるようですが。
なんと言っても注目はエンタープライズのサポート、プッシュeメールなんかが全部できるようになったこと（Blackberryから乗り換え組も出そうな…？）、ゲーム（Spore!）、携帯ネットワークはダメですけどWiFiでならVoIPができるようになること、などですね。個人的には携帯振るだけでUNDOできたり、加速度センサの活用が｢へ～｣という感じでした。
優秀な開発者には起業のお金まで面倒を見る1億ドルの新ファンド創設の発表まであって、これまでアングラだったデベロッパーにもやっと陽の当たる表通りが拓けましたね！ ま、作ったアプリはアップル直営のネットショップ｢App Store｣通してしか売れないんですけど…。でも売り上げの70％は貰えるそうなので一歩前進です。あ、でも、ポルノ、犯罪系、バンド食いのアプリはダメダメですよ！
アプリ開発は開発者フォーラムに入会金99ドル払うと今すぐ着手できます。一般の利用者が新アプリ使えるのは次期アップデートの6月。touchも共通です。
では、今朝アップル本社で行われたSDK詳細発表のイベントよりポイントを拾っておきましょう（ちょっと乱文です）。
・マウスとキーボードがベースのCocoa。これをアップルは自社のマルチタッチ技術と合わせてiPhone SDK用に｢Cocoa Touch｣を実現しました。
・コアOSはOS Xのカーネル、ライブラリシステム、BSD TCP/IP、ソケット、セキュリティ、パワー管理、キーチェイン、認証、ファイルシステム、Bonjour。
・Cocoa Touchの開発では、Cocoaで何かを作る際にみんなが知ってることとiPhoneタッチ入力のAPIのすべてを採用しました（Cocoaは素晴らしいんですけど、マウス＆キーボード入力がベースですからね）
・iPhone OSでは上記のものすべて（Cocoa以外）使いました。
・Cocoa、Media、Core Services、CoreOS
・音声・動画機能も全て入ってます。：Core Audio、Open AL、オーディオミキシング、音声録音、動画プレイバック、JPG/PNG/TIFF、PDF、Quartz （2D） Core Animation、OpenGL ES
・｢みなさんアップルに期待するのはメディアのレイヤーが全てでしょう｣
・ SQLite、Core Locationも入ってます。
• Cocoa Touch： マルチタッチのイベント／コントロール、加速度センサ、ビュー・ヒエラルキ、位置情報、アラート、ウェブ専用ビュー、人物ピッカー、画像ピッカー、カメラ。
・OpenGL ESはOpenGLのエンベッドされたバージョン。
・そこから始め、iPhone実装用に最適化（←前の項目の話？）。
・Xcodeはアップルの開発環境です。アップルはMac OS X用に作るものはすべてXCodeで作ってます。
・｢これはiPhone OSのアーキテクチャであり市場に出回っているモバイル端末用のプラットフォームでは最も進化したもの。他のどんなモバイル端末用プラットフォームよりも当社は数年先を行ってます｣
・統合化されたドキュメンテーション。｢SDKには素晴らしいドキュメンテーションがたくさん入ってます。どれもソフトウェア内からアクセスすることができます｣
・プロジェクト管理、統合されたソース管理
・リモート・デバッガみたいにiPhoneに接続して、Mac上の自分のアプリのパフォーマンスはiPhoneからリアルタイムに見ることができます。
・Instruments:｢パフォーマンス解析ツールの簡易版スイート｣
・Cocoa Touchのコントロールはすべて｢Interface Builder｣に搭載
・Interface Builder：｢ドラッグ＆ドロップみたいに簡単に自分のUIを作ることができます｣
・リモート・デバッガ： iPhoneにプラグインすると、iPhone上でライブで動作。
・iPhoneアプリは今お使いのMacのシミュレータで走らせることができます。XCodeとサイド・バイ・サイドで並べても動作は良好です。
・新iPhone開発用ツール｢iPhone Simulator｣リリース
・最大値・最小値、リアルタイムの情報、時系列表示、複数データトラックも見れます。
プレスリリース（英文）もはっときましょう。
Apple Announces iPhone 2.0 Software Beta
Includes SDK & Built-in Microsoft Exchange ActiveSync
CUPERTINO, Calif., March 6 /PRNewswire-FirstCall/ -- Apple(R) today previewed its iPhone(TM) 2.0 software, scheduled for release this June, and announced the immediate availability of a beta release of the software to selected developers and enterprise customers. The iPhone 2.0 beta release includes both the iPhone Software Development Kit (SDK) as well as new enterprise features such as support for Microsoft Exchange ActiveSync to provide secure, over-the-air push email, contacts and calendars as well as remote wipe, and the addition of Cisco IPsec VPN for encrypted access to private corporate networks.
"We're excited about creating a vibrant third party developer community with potentially thousands of native applications for iPhone and iPod touch," said Steve Jobs, Apple's CEO. "iPhone's enterprise features combined with its revolutionary Multi-Touch user interface and advanced software architecture provide the best user experience and the most advanced software platform ever for a mobile device."
The iPhone SDK provides developers with a rich set of Application Programming Interfaces (APIs) and tools to create innovative applications for iPhone and iPod(R) touch. Starting today, anyone can download the beta iPhone SDK for free and run the iPhone Simulator on their Mac(R). Apple today also introduced its new iPhone Developer Program, giving developers everything they need to create native applications, and the new App Store, a breakthrough way for developers to wirelessly deliver their applications to iPhone and iPod touch users.
With the iPhone SDK, third party developers will be able to build native applications for the iPhone with a rich set of APIs, including programming interfaces for Core OS, Core Services, Media and Cocoa Touch technologies. The iPhone SDK will allow developers to create amazing applications that leverage the iPhone's groundbreaking Multi-Touch(TM) user interface, animation technology, large storage, built-in three-axis accelerometer and geographical location technology to deliver truly innovative mobile applications.
Apple has licensed Exchange ActiveSync from Microsoft and is building it right into the iPhone, so that iPhone will connect out-of-the-box to Microsoft Exchange Servers 2003 and 2007 for secure over-the-air push email, contacts, calendars and global address lists. Built-in Exchange ActiveSync support also enables security features such as remote wipe, password policies and auto-discovery. The iPhone 2.0 software supports Cisco IPsec VPN to ensure the highest level of IP-based encryption available for transmission of sensitive corporate data, as well as the ability to authenticate using digital certificates or password-based, multi-factor authentication. The addition of WPA2 Enterprise with 802.1x authentication enables enterprise customers to deploy iPhone and iPod touch with the latest standards for protection of Wi-Fi networks.
The iPhone 2.0 software provides a configuration utility that allows IT administrators to easily and quickly set up many iPhones, including password policies, VPN setting, installing certificates, email server settings and more. Once the configuration is defined it can be easily and securely delivered via web link or email to the user. To install, all the user has to do is authenticate with a user ID or password, download the configuration and tap install. Once installed, the user will have access to all their corporate IT services.
The iPhone 2.0 software release will contain the App Store, a new application that lets users browse, search, purchase and wirelessly download third party applications directly onto their iPhone or iPod touch. The App Store enables developers to reach every iPhone and iPod touch user. Developers set the price for their applications -- including free -- and retain
70 percent of all sales revenues. Users can download free applications at no charge to either the user or developer, or purchase priced applications with just one click. Enterprise customers will be able to create a secure, private page on the App Store accessible only by their employees. Apple will cover all credit card, web hosting, infrastructure and DRM costs associated with offering applications on the App Store. Third party iPhone and iPod touch applications must be approved by Apple and will be available exclusively through the App Store.
The iPhone SDK provides a reliable, fast and secure way to create innovative applications for the iPhone and iPod touch. In addition to the rich set of iPhone OS APIs, the iPhone SDK also provides advanced tools for creating native iPhone and iPod touch applications including: Xcode(R) for source code editing, project management and graphical debugging; Interface Builder with drag and drop interface creation and live preview; Instruments to monitor and optimize iPhone application performance in real time; and the iPhone Simulator to run and debug applications.
During the beta iPhone SDK program, a limited number of developers will be accepted into Apple's new iPhone Developer Program and offered the ability to get code onto iPhones for testing. The Standard Program costs $99 (US) per year and gives members an iPhone SDK and development tools; access to
pre-release iPhone software; technical support; the ability to get code onto iPhones for testing; and distribution of applications via the new App Store. The Enterprise Program costs $299 (US) per year.
In addition to these new iPhone network and security features, the beta iPhone 2.0 software provides several new Mail features such as the ability to view PowerPoint attachments, in addition to Word and Excel, as well as the ability to mass delete and move email messages.
Pricing & Availability
Apple plans to release the final iPhone 2.0 software, including the iPhone SDK and new enterprise features, as a free software update for all iPhone customers by the end of June. Third party applications created for the iPhone will also run on the iPod touch, and iPod touch users will be required to purchase a software update to run these applications. The free beta iPhone SDK is available immediately worldwide and can be downloaded at developer.apple.com/iphone/program. The iPhone Developer Program will initially be available in the US and will expand to other countries in the coming months. Apple is accepting applications beginning today from enterprise customers who would like to join the private iPhone Enterprise Beta Program (http://www.apple.com/iphone/enterprise).
