It's likely that Apple's iOS 5 will will address an problem that deprived some Web applications from the speed boost that found the mobile version of Safari.
On iOS, Internet sites and Web applications could be released from a symbol the user places about the desltop from Safari. Individuals applications did not take advantage of a speed-up that included Safari in the new ios 4.3, though: the Nitro engine that runs Web-based code is designed in the ever-more-important JavaScript language.
It seems iOS 5 could address this problem, though.
"Did they fix the bug from 4.3 where desltop Web applications avoid using Nitro?" requested user MatthewPhillips on Hacker News yesterday. The reply from Xuzz: "This really is most likely breaking my NDA to express this, but yes, they did. Web.application presently has the 'dynamic-codesigning' entitlement, which allows Nitro."
Gleam method to create Web applications on iOS that does not use Safari proper, an interface known as UIWebView.
That does not turn to receive the Nitro speed-up for security reasons including just-in-time (JIT) compilation that Nitro uses to produce faster versions of JavaScript software quickly.
"They do not [get Nitro benefits], but that is a burglar restriction," Xuzz stated. "They cannot give dynamic-codesigning to any or all applications, or their security (which that hinders, like a requirement make it possible for the JIT) would then be useless."
Apple did not immediately react to a request comment.
