Editor’s note: This article comes from the WeChat public account “ID-iou” (ID: i-yiou), author Huang Zhilei, editor Wang Fangyu.36 krypton released with authorization.

In the early morning of June 23, Beijing time, due to special reasons, Apple brought the opening speech of the Apple Developer Conference “WWDC20” for the first time in the form of recording and broadcasting.As Apple’s annual regular meeting, WWDC mainly shows the latest technology changes to developers around the world. This is also the first time in 33 years that Apple has changed the opening speech of WWDC to online.
In the keynote speech on the first morning, Apple released updated systems for various platforms, including iOS, iPadOS, watchOS, tvOS, and macOS, and the Mac self-developed chip plan based on the ARM architecture has finally landed.
iOS 14: New design, more like Android
Maybe Apple doesn’t want to admit it, but in terms of system functions, the boundary between iOS and Android is already very blurred.iOS 14 has redesigned the core elements, updated from App resource management, widgets, Siri, App Store, etc.
App resource management: The new App Library is used to help users quickly organize apps. Users no longer need to manually package the first screen and other screen apps. After removing the off-screen desktop, the apps will be intelligently classified into folders and gestures.The operation can quickly enter the App Library.
Update widgets: iOS adds more widgets and provides new widgets of different sizes. The new widgets can be placed anywhere on the homepage, and components of the same size can be stacked in one place. Users can slide up and down to view; Apple also “finally” updatedWith the “Picture in iPhone” function, you can place the picture-in-picture video or hide it in the frame to continue playing when using the application.
Siri: Compared with the previous full-screen response, Apple has restructured the interaction mode. Siri interaction becomes a small pop-up window, which is more compact and supports sending audio information. The built-in keyboard will also be equipped with the same voice recognition technology as Siri; at the same time Siri can provide11 different languages ​​offline translation, support automatic recognition of voice and translate into corresponding text and voice.
App Store: With the new app store, the new App clips on iOS 14 can help developers build lightweight applications. Developers can use the development tools to create applications that do not exceed 10 Mb. Users can use QR codes, NFC, clip codes, etc.The method can call the simple App function without downloading the complete App. At the same time, the App Store supports the use of Apple accounts to complete multiple application logins.
iMessage: The conversation mode has been redesigned to provide features such as pinning important contacts, more age image selection for memoji, custom avatars for groups, and response to specific words in conversations.
Apple Maps: Reconstructed map application, will provide three-dimensional and street view information, increase riding mode (first support for New York, Los Angeles, San Francisco Bay Area, Shanghai and Beijing), support maps to track new energy vehicle battery conditions, EV routing can also be based on the ownerThe car situation automatically recommends a suitable charging station, and Chinese users can also enter their own license plates to avoid entering the restricted number area.
Car Play: Apple launched the Digital Car Key (CarKey) program. iPhone or Apple Watch can use Apple’s self-developed U1 chip and NFC to realize private car sensor unlocking. Owners can also share keys and set permission conditions. BMW 2021 version 5 series models willMake a starter.Car Play has updated wallpapers and icons for new features. iOS 13 will also support this feature. Apple claims that 80% of new cars will support the new Car Play in the future.
The launch time of IOS 14 is unknown, but the earliest can support the iPhone 6s series phones released 5 years ago, which is good news for old users.
iPadOS 14: I hope you don’t put down the Apple Pencil
iPadOS currently has more than 1 million iPad apps. In the new iPadOS 14, Apple has redesigned interactions and components, added sidebar functionality, simplified the toolbar, and placed more emphasis on Apple Pencil interaction.Similar to the iOS update, siri, incoming calls, and third-party applications no longer follow the full-screen response. At the same time, a new global search is designed for the iPad. Similar to the Mac, the search box also supports information such as web pages and apps.
Apple Pencil’s interaction has become smarter and more comprehensive in handwriting support.With the help of machine learning, in iPadOS 14, users can type text in any input box and support mixed Chinese and English numeric typing recognition. In drawing mode, the shape drawn by Apple Pencil can also be intelligently recognized as a more rigorous straight lineOr regular graphics, and handwritten text will also support text copy and call.
In the iPadOS link, AirPods supports seamless switching between multiple Apple devices. The new feature Spatial Audio allows AirPods Pro to simulate 5.1, 7.1 channels, and even Dolby full scene sound effects. In order to enhance the realism of the sound field, the headsetA gyroscope will sense the position of the head and relatively simulate the sound field corresponding to the action.
watchOS: The official third party death
At present, there are more than 20,000 apps in watchOS. The new system puts more emphasis on dial customization and health management. Apple has added more complex sports health and sleep monitoring functions, and has introduced hand washing detection functions in due course.Users and developers can customize their dials, place a variety of information on the interface, and support dial sharing. Users can obtain new dials through friends, merchant displays, and in-app updates.
The biggest update of watchOS this time is to support a third-party sleep monitoring function with higher voices. In addition to being able to do sleep tracking, Apple watch makes the interface between the phone and the watch close to sleep by means of Wind Down, such as a dull interface and simpleThe lock screen interface, the watch also supports silent touch alarm.
In the new Fitness application, watchOS has also added riding navigation and dance movement recognition. The algorithm can accurately calculate the movement trajectories of the arms, legs and body under the dance, thereby calculating calorie consumption more accurately.
tvOS: New content links with HomeKit
As the home of software updates this time, the new development of Apple’s own streaming service, AppleTV+, will certainly not be absent, although this part of the content has little to do with most users in China.
In addition to emphasizing that Apple TV+ will launch the sci-fi series adapted from Asimov’s “Base”, Apple’s new version of tvOS will also have a new control center for controlling HomeKit components, and the new UI will also support multi-user, picture-in-picture mode.Support other devices to quickly cast screens and Arcade game subscription services, users can control through Xbox or Adaptive Xbox One, and HomePod will also support third-party music services.
In addition, Apple also updated the HomeKit ecosystem, adding global management functions for home devices, smart light bulbs will be accompanied by adaptive lighting for a day, and the security camera also supports smarter area scanning and friend identification. With the help of the photo function, the security device can identify family and friends andReminder through HomePod, Apple TV can also directly talk with visitors.
At the same time, Apple also announced that it will join Amazon, Google and other companies to build a smart home ecosystem.
macOS: New design, no fear of plagiarism
macOS is still the focus of WWDC every year, this time macOS once again ushered in a major update.Apple Software Engineering Vice President Craig Federighi said that although the Apple marketing team came up with many names for macOS, there are still a lot of imitators, and this time Apple will not allow competitors to follow suit.
The new version of macOS is named Big Sur (Big Sur). This naming rule continues to use the name of beautiful scenery. This western California scenic area in the United States has a 160-kilometer waterfront and was once named “Life of a Person” by National Geographic.One of the 50 places to go”.
Craig Federighi said that Big Sur will be a new start for macOS and the largest UI upgrade in 2 years. A large number of native applications have been redrawn, the Dock has been redesigned, the dialog boxes have become pure white and pure black, and the photo and mailbox application interfaces have been upgraded., The component also came to macOS, developers can design their own components, the new control center on the main interface of the system can quickly change the brightness, turn on the dark mode, etc.
Safari has also ushered in a major update. Apple claims that its performance surpasses that of its rival Chrome by 50%. It provides a privacy index button for each web page to facilitate the use of information. At the same time, with the help of new extension standards, users can customize permissions when extending access to pages., Including limited to one day, only when staying on this page or permanently visiting.
Safari will also support customizing the start page, changing the background, etc.
Self-developed Mac chips: products will have a 2-year transition period
The highlight of this conference was put at the end. Cook officially announced that after using the Intel chip for 15 years in the Mac product line, Apple will launch a new self-developed chip (Apple Silicon). The first self-developed chip product will beIt was launched at the end of 2020.Apple said it will spend two years helping developers and users complete the transition from the old architecture to the new architecture.
In Apple’s mysterious laboratory, Apple executives said that the chip research and development work took Apple more than ten years. Apple’s self-developed chips began with the iPhone. Initially, they hoped to balance performance and power consumption. They are equipped on the iPhone, iPad and Apple Watch.After self-developed chips, Apple finally adopted self-developed chips on Mac.
Although the specific technical architecture of the new chip has not been announced, Apple claims that the application architecture is unified with iOS and iPadOS, the Mac supports the direct running of iPhone and iPad applications, and the ARM architecture should be used as previously rumored.The new chip integrates multiple sub-units, including neural engine, machine learning accelerator, and high-performance GPU. At present, the Apple developer website has released instructions for the development of the new chip.
Apple claims that the new chip has powerful performance and balanced functions, and developers can use the performance to do more development work.
In the demonstration, the Apple prototype was a computer equipped with an A12Z chip. This chip equipped with iPad P Fusion not only runs perfectly on macOS Big Sur, but also on Final Cut Pro X and Logic Pro X that require high-performance support.Run smoothly and even stream multiple files.
In addition to a large number of native applications, Apple will also cooperate with institutional developers such as Microsoft and Adobe to complete the adaptation of applications such as Office and Light room.
In order to facilitate developers to complete application migration and development, Apple’s Xcode, Universal 2, Rosetta 2 and virtual technology will help developers complete the migration work faster.
Developers only need to open the latest Xcode to recompile the app and get new applications within a few days; Universal 2 is a new Universal binary program code. Developers can run on Intel chips and Macs with Apple’s self-developed chips for easy development.Those who use the new Mac’s native capabilities to run their own apps.
Compared with developers who complete development under the new architecture, Apple hopes that users can experience all the apps earlier, so that applications that have not yet been developed can be used.
In the past, Apple used Rosetta to run PowerPC apps on Intel chip Macs. The Rosetta 2 launched this time will solve the same problem. Old apps will be automatically translated into apps that can run on the new Mac chip when installed, allowing users to runMac apps that have not been updated.
In addition, Apple introduced new virtualization technology (Virtualization) to Big Sur to help developers run Linux environments or Docker tools to better complete development work.
To help developers complete applications faster, Apple will launch the Quick Start program on the day of the conference. With the help of priority developer technical support (DTS) and Developer Transition Kit (DTK) hardware, developers can also develop before mass production.DTK hardware is a Mac mini based on A12Z chip, including 16GB flash memory and 512GB SSD, pre-installed Big Sur developer beta version and Xcode, and will start shipping this week.
Ecological layout is still leading
As mentioned earlier, Apple, which has always been harried by competitors’ plagiarism, has become more homogenous with Android in software functions, such as Android users’ common component functions, picture-in-picture, and even CarKey. Samsung has cooperated with BMW as early as 2018., The mobile phone can become the car key through NFC.
However, functional homogeneity is not a weakness of Apple’s R&D. On the contrary, in cross-platform R&D, Apple has found its own advantage in a familiar way: a unified experience under the ecology.
Whether it is seamless switching between AirPods devices, or Mac supports iPhone and iPad applications, Apple’s focus has shifted to the bottom and extensive development support layout.
Compared with the fragmentation of the Android ecosystem, the system and hardware still cannot be unified. Not only can not a large number of development capabilities be gathered, but also the definition of hardware standards to software is lost, which further reduces the sense of experience coordination within the ecosystem.
For example, Huawei and Xiaomi in the Android camp, because mobile phones and computer hardware cannot be unified, although cross-platform functions such as file transfer are already available, they have never been able to complete the unification from hardware to software.
On the one hand, Apple develops and develops chips or hardware to the bottom layer, and supports developers from the bottom layer standards, as far as possible without wasting hardware performance, and achieving uniformity between hardware and software; on the other hand, Apple completes micro-innovation of toothpaste on the systemFocus on supporting developers and improving application construction.
After completing the Mac chip self-research, Apple’s ecological layout will be strongly supplemented.Whether it is to continue to “learn” competitors or continue to do software micro-innovation, Apple’s ecologically unified and complete user experience is still difficult to replace, and competitors still need to find a way to overtake in corners.
