What if there were a way for Siri to do more than it does? What if it could control everything? We're getting there. Siri has been tweaked to enable voice controls of third-party applications. It's a proxy setup that catches instructions, converts them, and eventually sends the final dictations to the app. FastPdfKit is the first app to have this support, and while it's tough to explain in words, there's a video here that showcases it well. The real question is this: how prevalent will this become, and will Apple introduce wider support of this in the next major build of iOS?
