Looking to the future, it’s likely that Apple will solve this problem by using a technique known as , in which the browser’s rendering engine will be essentially kept into a completely separate execution space from the app that hosts it. This approach, which is part of the upcoming engine that Apple is developing, ensures that the browser can be provided with the appropriate privileges without causing the latter to spill into the hosting application as well. When that happens, we should finally see Nitro and its speed-ups become available to all developers.

Of course, it’s entirely possible that Apple is at work on a completely different solution. As you can see, however, there is a perfectly logical explanation why things are the way they are—one that, incidentally, doesn’t need to ascribe any nefarious intention to the company. Regardless, I am sure that Apple’s penchant for secrecy will manage to keep the conspiracy theory enthusiasts busy for years to come.
