Apple has been promoting HTML5 as an alternative to Flash for video and other content on the iOS, citing performance reasons for not allowing the Flash runtime to be installed on iOS. Flash as a runtime is not available on Apple's iOS devices: iPhone, iPod touch and iPad[24] but can be compiled as a native iOS application through Adobe's iOS packager in Flash CS5 Professional. According to Adobe Labs, Adobe's iOS Packager “offers Flash developers a fast and efficient method to reuse existing code from ActionScript 3 projects
to deliver native applications on iOS devices”.
In April 2010, Steve Jobs, the co-founder and then-chief executive officer of Apple[26] criticized Flash technology in an open letter posted to Apple's website, offering an explanation for why Apple does not support Flash on its mobile devices. Among his criticisms were that "Flash was created during the PC era – for PCs and mice," and that "Flash is no longer necessary to watch video or consume any kind of web content." He also described Flash's performance and security as sub-standard.
In November 2010, a Wired columnist said "allowing Flash — which is a development platform of its own — [on the iPhone] would just be too dangerous for Apple, a company that enjoys exerting total dominance over its hardware and the software that runs on it. Flash has evolved from being a mere animation player into a multimedia platform capable of running applications of its own. That means Flash would open a new door for application developers to get their software onto the iPhone: Just code them in Flash and put them on a web page. In so doing, Flash would divert business from the App Store, as well as enable publishers to distribute music, videos and movies that could compete with the iTunes Store."
Also in April 2010, Apple modified its iOS developer agreement to limit the development of iOS apps to the use of a small set of Apple-approved programming languages and tools. Adobe's iOS packager was seen as the target of these new rules.[29] However, because the new rules were broadly written, and did not cite Adobe's iOS Packager specifically, they also potentially restricted the development of many popular iOS games and applications created using other non-approved application frameworks, such as MonoTouch, Unity3D, and Lua.
In September 2010, after having "listened to our developers and taken much of their feedback to heart", Apple removed the restrictions on third-party tools, languages and frameworks, removing uncertainty from developers who used these third-party tools, and again allowing the deployment of Flash applications on iOS using Adobe's iOS Packager.
