2005年举行的WWDC大会入口报到处。

WWDC为“苹果电脑全球研发者大会”（Apple Worldwide Developers Conference）的简称，每年定期由苹果公司（Apple Inc.）在美国加州举行。大会主要的目的是让苹果公司向研发者们展示最新的软件和技术。

在近几年的大会中，苹果公司通常会发表Mac OS X操作系统下一个版本的预览。参加大会的研发者人数约在2000至4200人之间。在2007年的WWDC，史蒂夫·乔布斯在其简报内称有超过5000人参加，是历届最多人参与的大会。

目录

历史

第一届的WWDC是于1983年在加州的蒙特瑞举行。1998年至至2002年,WWDC都在5中旬中举行。2003年至2005年移至6月举行去更好地实践苹果公司之前的承诺。在2006年WWDC移至8月推测可能是为了要有更多的准备时间，以能在大会上展出下一代的操作系统Mac OS X v10.5“Leopard”，以及公开新英特尔处理器的最佳时机。自1998年起，大会通常始于苹果的简报，由执行长史蒂夫·乔布斯（Steve Jobs）主持，让这个活动被称为“史蒂夫简报”（Stevenotes）。近期的WWDC将焦点放在示范与发布即将登场Mac OS X版本的预演。

WWDC 1996

WWDC '96几乎完全将焦点放在“Copland”计划，其在当时可以被某种程度展示。吉尔．艾米里奥表示该系统根据时间表应于晚夏推出beta版本，并于秋季末推出最初的商业版本。然而，会议中仅提供非常有限的现场示范，也完全未给出该操作系统的beta版本。

WWDC 1997

WWDC '97是收购NeXT后的第一次大会，也将焦点放在使用OpenStep作为下一代Mac OS基础的努力。当时的计划是介绍名为“Rhapsody”的新系统，其基于一个OpenStep版本，并修改外观使之更符合Mac的观感、“黄盒”、以及能让既存Mac应用程式在OS模拟下执行的“蓝盒”。

The show focused primarily on the work in progress, including a short history of the development efforts since the two development teams had been merged on Feb 4.[1] Several new additions to the system were also demonstrated, including tabbed and outline views, and a new object-based graphics layer (NSBezier).

WWDC 1998

In response to developer comments about the new operating system, the "big announcement" at WWDC'98 was the introduction of Carbon. Carbon was effectively a version of the "classic" Mac OS API implemented on OpenStep. Under the original Rhapsody plans, classic applications would run in sandboxed installation of the classic Mac OS, (called the Blue Box) and have no access to the new Mac OS X features. To receive new features, such as protected memory and preemptive multitasking, developers would have to rewrite their applications using the Yellow Box API. Developer complaints about the major porting effort to what was then a shrinking market and warnings that they might simply abandon the platform, led Apple to reconsider the original plan. Carbon addressed the problem by dramatically reducing the effort needed, while exposing some of the new functionality of the underlying OS.[2]

Another major introduction at WWDC'98 was the Quartz imaging model, which replaced Display PostScript with something akin to "display PDF". Although the reasons for this switch remain unclear, Quartz also included better support for the existing QuickDraw model from the classic OS, as well (as it was later learned) as Java2D. Supporting QuickDraw directly in the graphics model also led to a related announcement, that the Blue Box would now be "invisible", integrated into the existing desktop as opposed to an entirely separate window.

WWDC 1999

WWDC'99 was essentially a "progress report" as the plans outlined in WWDC'98 came to fruition. Three major announcements were the "opening" of the operating system underlying the new OS as [[Darwin]], improvements to the Macintosh Finder, and the replacement of QuickDraw 3D with OpenGL as the primary 3D API. The system formerly known as OpenStep, and referred to during development as "Yellow Box" was formally re-named "Cocoa".[3][4] 2563 developers attended.

WWDC 2000

Much the same as WWDC'99, 2000 was another "progress report" on the way to the upcoming release of Mac OS X. Recent changes included a modified Dock and improved versions of the developer tools. "Developer Preview 4" was released at the show, with the commercial release pushed back to January 2001. Additionally, WebObjects was dropped in price to a flat fee of $699 US.[5] Approximately 3600 developers attended.

WWDC 2001

Mac OS X had only recently been released, but WWDC'01 added the first release of Mac OS X Server shipping and WebObjects 5.[6] Over 4000 developers attended. Leather jackets with a large blue "X" embroidered on the back were distributed to attendees.

WWDC 2002

Mac OS X v.10.2 and QuickTime 6 was presented.[7] Apple also said farewell to Mac OS 9 with a mock funeral, and told the developers that there would be no more Mac OS 9 development, reinforcing that the future of the Mac was now entirely on Mac OS X.[8]

WWDC 2003

WWDC'03 demonstrated the Power Mac G5, distributed a preview of OS X Panther (10.3), and the introduction of the "iApps". Rendezvous (now known as Bonjour) was also announced. Attendees received an iSight web camera.

WWDC 2004

WWDC 2006于6月28至7月2日在旧金山莫斯考尼西(Moscone West)举行。Steve noted that 3500 developers attended and that was a 17% increase from 2003. New displays were introduced in 23 and 30-inch widescreen. Mac OS X Tiger (10.4) was also previewed. All attendees received a developer preview of Tiger, a simple grey t-shirt with the Apple logo on the front and "WWDC2004" on the back, a backpack capable of holding a 17-inch PowerBook, and a copy of Apple Remote Desktop 2.0.

WWDC 2005

WWDC 2005于6月6至10日在旧金山莫斯考尼西(Moscone West)举行。After a basic market update, Jobs announced that Apple would transition to Intel processors and the x86 platform. The keynote featured developers from Wolfram Research, who discussed their experience porting Mathematica to Mac OS X on the Intel platform. 3800 attendees from 45 countries attended the event. There were 110 lab sessions, 95 presentation sessions, and 500+ Apple engineers on site.

WWDC 2006

WWDC 2006于8月7至11日在旧金山莫斯考尼西(Moscone West)举行 with the keynote presentation hosted by Steve Jobs.

来自48个国家约4200位的研发者参加了这次活动，也是历年来最大规模的WWDC大会。有140场研发研讨会和100场实验室（hands-on labs）活动。并且有超过1000名的苹果工程师参加了这次的活动。

在零售方面，发表的最新消息包括：已有超过1千7百万名顾客造访苹果官方商店（Apple Store），在上一季销售了1千3百万台麦金塔电脑，其中有50%都是首次接触麦金塔电脑的使用者。第三协议厂商软件在Apple Store的销售金额达到50亿美元。简报中也指出麦金塔电脑的销售成长速度已超过PC电脑，苹果的笔记型电脑市场占有率也提升了一倍（从6%至12%），这是因为发表了“MacBook”机型的缘故。

如同各方预期，大会上也发表了用来取代PowerMac G5系列的专业工作站电脑“Mac Pro”。Mac Pro搭载了两颗英特尔Xeon 双核心 2.0 GHz的处理器、1 GB的内存、160 GB硬盘，以及256MB的显卡。Xserve服务器也发表了更新，同样搭载双核心的Xeon处理器。

而苹果电脑下一代操作系统Mac OS X v10.5“Leopard”也在大会上发表了预览，包含完整支援64位元的应用程式、Time Machine（档案还原），内建Boot Camp、Front Row以及Photo Booth软件，并发表“Spaces”虚拟桌面功能、改进的Spotlight搜寻技术、Core Animation、辅助使用程式技术、Mail软件的强化、新的Dashboard功能，以及Dashcode和iChat的更新等。Leopard预计约在2007年春季上市。

WWDC 2007

WWDC 2007于6月11至15日在旧金山莫斯考尼西(Moscone West)举行 with the keynote presentation hosted by Steve Jobs. Apple showed off a feature-complete beta of Mac OS v10.5 "Leopard", though its release date was pushed back to October. Jobs announced that Safari would now be available for Windows and announced support for third-party development for the then upcoming iPhone via online web applications through the iPhone's web browser. Jobs also announced the launch date for the iPhone, which he was widely expected to do, as June 29, 2007. Jobs also announced that Apple Safari, Apple's proprietary web browser, would run on the iPhone; and that Apple (at the time) had no plans to release an iPhone SDK, meaning that developers would have to use standard web protocols. Additionally Jobs noted during the keynote that over 5000 attendees were present at WWDC07, breaking the previous year's record.

WWDC 2008

WWDC 2008于6月9至13日在旧金山莫斯考尼西(Moscone West)举行。

Apple reported that, for the first time, the conference had sold out. There were three tracks for developers, iPhone, Mac, and IT.

Announcements at the keynote included the App Store for iPhone and iPod Touch, the stable version of the iPhone SDK, a subsidized 3G version of the iPhone for Worldwide markets,[9] version 2.0 of the iPhone OS, Mac OS X v10.6,[10] and the replacement/rebranding of .Mac as MobileMe.[11]

WWDC 2009

WWDC 2009于6月8至12日在旧金山莫斯考尼西(Moscone West)举行[12]，而苹果报道2009年大会入场券于四月末就已全数售罄。简报中宣布包括于三月对开发者提供的iPhone OS 3.0之发布、Mac OS X v10.6的展示、以及新的iPhone 3G S。苹果的产品行销部副总裁长菲力普·舒勒负责今年的WWDC简报，而非传统上的发表者，苹果执行长史蒂夫·乔布斯，后者自年初便因医疗原因离开岗位。[13]
