In a live interview, Craig Federighi and Phil Schiller talk about WWDC’17 releases

For the second consecutive year, Apple sent two of its top executives to the "Talk Show Live" with John Gruber, blog editor Daring Fireball. For about an hour, Phil Schiller (senior vice president of global marketing) and Craig Federighi (senior vice president of software engineering) answered some questions from Gruber, covering behind the scenes and their overview of this week's major releases.

We had the opportunity to participate live in the event, held at the beautiful California Theater in San Jose, one block from the convention center where Apple hosted the Worldwide Developers Conference (WWDC) 2017. For those who did not have this opportunity, the production of The event published the complete recording, from which we highlight the main highlights below.

Safari and privacy

Apple's web browser gets a major update on macOS High Sierra, making it, in Federighi's words, ?the world's fastest web browser on the desktop?. For him, it is important to value the work of the company's teams around this, while from a functional point of view, new features such as automatic video blocking and prevention of tracking integrated into the product will help users to live more conveniently and privately with content in the Internet.

Speaking specifically of tracking blocking, Federighi explained in more detail how this feature has been exploited over the years by Apple, as advertising companies (I'm looking at you, Google!) Have created methods to circumvent them.

Photos and face synchronization

Among the functions covered quickly in Monday's keynote for the High Sierra, the synchronization of faces in the Photos app was one of the most applauded for me, particularly, goes to the column ?Finally!?. And Apple executives admitted that one of the reasons for this not being delivered along with last year's changes was the time needed to improve it.

Basically, it was necessary to make it work so as not to require a huge transfer of data during the process. This allowed the company to optimize it to work in an encrypted and anonymous way, in the same way as the existing local machine learning for the recognition of objects and environments.

In addition, Federighi highlighted the work done by the Fotos team (and other apps) with performance. In product evaluations, engineers were challenged to demonstrate results on the smallest-capacity Macs they could take, with libraries of more than 100,000 photos. Very positive results are expected from the refinements applied to the system in other apps, including Finder, Mail (?) and others.

Apple File System

Extremely insane for tech connoisseurs the way Apple has managed to make APFS friendliness possible by invisibly updating the file system of hundreds of millions of iOS devices overnight, in a common system update.

However, one of the greatest moments of euphoria and applause in the interview was Federighi's explanation of the testing process for this change. According to him, part of them was carried outin the general public. This means that, during maintenance updates prior to the final release, small samples from users around the world were selected for testing. During testing, the file system was converted, its results sent to Apple for analysis, and then the user's device returned to its previous state!

So, if at some point in the past year an iOS update lasted for hours on your iPhone or iPad, perhaps you were drawn. ?

iMac Pro and VR

We saw it as a ?stop-gap?, but in Schiller's view, the iMac Pro is not just that. Many expect the new Mac Pro to be launched in 2018, but at the same time, Apple decided to respond to the desire of customers who always wanted to obtain greater computing power inside an iMac, which has now captivated users in the advanced and advanced sectors as a product. professional.

Schiller says the initial response to the newall-in-one it was positive, and considerable success was expected of him, but he had no figures on it. Federighi took the opportunity to highlight the company's work in offering content creation tools for VR, in which he expects that some of them will come from MacBooks Pro, once users can work with external GPUs that will be launched from next year.

A summary of how this was conceived is found in the interview and, from the technical point of view, it was really cool to hear.

iPad Pro (and ProMotion)

Federighi cited that the work on the technology behind the 120Hz screen created for the new iPad Pro came on the Mac, where the first prototypes of this technology were powered by Macs Pro. From there, the work was taken to the other hardware teams, software and accessories.

iOS 11 and Siri

There are many details about the technology that enablesdrag & drop between apps on iPads, which does not compromise data security between apps, according to Federighi. One of the techniques needed to make it possible was to migrate the devices to APFS, because thanks to cloning techniques andsnapshots, the system performs copies between the safe directories of each application without direct impact to disk (until changes are made to the destination app, of course).

Executives highlighted Siri's advances, in particular how Apple's speech recognition has evolved to make it safe (in order to speak "Hey, Siri" in an audience of thousands of people without their iPhones invoking the assistant) and is able to recognize the original device, when the user has more than one device.


Gruber was quick to compare the newspeaker of Apple with iPod Hi-Fi, reminding the old strategy of the company to offer a device of the kind for iPods in the past. Schiller commented that the scenario is quite different these days: according to him, the company's audio engineering team has evolved a lot in recent years and he hopes the product's success will come from its superior audio quality from competitors, as well as from Siri's presence on the device.
