This year's WWDC mainly released six aspects: tvos, watchos, high Sierra, IOS, iPad pro and homepod. Let's analyze the specific contents in detail below.


Tvos has reached a partnership with Amazon. Apple introduces Amazon app into tvos, so that users can watch Amazon TV dramas and self-made dramas through Apple TV.

The new system high Sierra will release the developer version to developers at the end of June, and Mac users can update the official version in the autumn.

At the same time, at this year's conference, Apple also updated the IMAC series. The updated IMAC screen brightness can reach 500 nits and supports 10 bit color gamut. In terms of configuration, the latest i7 core processor is adopted, the space is increased to 2TB, equipped with updated SSD and faster GPU, which is 80% faster than the previous generation.

The updated IMAC also supports VR video and games. Apple specially introduced the new 27 inch iMac, which is designed for VR development, mainly thanks to the upgrade of GPU. It is worth mentioning that Apple announced at this conference that its products will support HTC vive platform, which also marks Apple's formal embrace of VR industry.

In addition, Apple has also brought a new IMAC pro. Apple has stuffed advanced workstation level hardware configuration into the narrow space of this IMAC pro.

IOS 11 is coming! The operation interface of IOS 11 has changed a lot this time, but there are not too many highlights. Cook teased his opponent, saying: "at present, 86% of IOS devices have been upgraded to IOS 10, while the upgrade rate of Android 7.0 is only 7%".

This year's IOS 11 is another important turning point for apple from flat to perspective. Its control center, lock screen and message interface are redesigned. You can see more message notifications by clicking on the lock screen interface. Different from IOS 10, the functions of its control center become block display. Using 3D touch pressure sensing technology, it can even adjust the brightness display of the flashlight, and also add functions such as personal hotspot switch and homekit home control.

In terms of homekit smart home application, it supports speakers smart speaker access. In addition, it has also been optimized and adjusted in terms of music interface. It is worth mentioning that Apple map has also upgraded its more powerful indoor navigation. Taking shopping mall navigation as an example, it can be accurate to every floor, and the main airports will be covered in the future.

As usual, the official version of IOS 11 will push updates and upgrades with the release of the new iPhone in September this year.

iPad Pro

The weight of the 10.5-inch iPad Pro is inconvenient. The screen is equipped with an ultra narrow frame. The true tone display technology is added, which has a wider color gamut, ultra-low reflectivity, improves the maximum brightness and supports HDR video. It also adopts a new promotion technology with a refresh rate of 120Hz, which is known as "smoother, sharper and faster response", and can better cooperate with the applepencil stylus, The delay is only 20ms, and even the refresh rate can be dynamically adjusted according to the load to save power consumption. For example, it can be reduced to 48Hz when watching video and 24Hz when displaying still photos.

In terms of performance, the new iPad Pro adopts a10x chip, which has been greatly improved in all aspects. The new iPad Pro has a 10 hour battery life, uses a usb-c interface, a 12 megapixel camera, and supports optical anti shake and 4K video recording.

It's not like a tablet at all. It adopts the 12 megapixel rear lens of the same iPhone 7, supports optical anti shake, f / 1.8, 6p lens, 4 flash lights and 4K video shooting. The front lens is 7 million pixels and supports fill light. IOS 11 launched drag and drop function for iPad pro, further liberating productivity.

As for the smart speaker homepod benchmarking Amazon echo and Google home, it has two color versions of space gray and white.

It is 7 inches high (less than 18 cm), equipped with apple A8 processor, 7 tweeters and a large low-frequency speaker. It can automatically identify the space and adjust the volume to fill the whole space with music.

The homepod costs $349 (about 2374 yuan) and is expected to land in the domestic market next year.


On the whole, this year's WWDC 2017 keynote feels like a hardware conference, but it is not difficult to interpret Apple's future technology layout for the application of artificial intelligence and VR / AR in the whole process.
