今日凌晨，WWDC 2019年全球开发者大会正式召开，苹果发布了最新 iOS 13。
最值得期待的呢，可以说是 iOS 系统首次推出深色模式，为 iPhone 带来截然不同的全新观感。
除了性能上的提升，比如面容 ID 解锁更加快捷、app 启动速度的提升、减少 app 所需的下载空间等等，在软件上也做了许多或大或小的更新，让我们一起来看看吧。
Apple iOS 13: the biggest new features coming to the iPhone
The Verge
As expected, Apple has announced iOS 13 onstage at WWDC 2019, giving a first look at the company’s latest software for the iPhone. According to Craig Federighi, Apple’s senior vice president of software engineering, iOS 13 is the “next big release for iOS,” and it will offer a variety of improvements to the operating system.
IMPROVED PERFORMANCE
性能提升
As with last year’s iOS 12 update, Apple is putting a big emphasis this year on improvements to performance, especially for older devices. Hopefully, the company has learned from its past issues where new versions of iOS resulted in slowed-down phones, although we’ll have to wait until iOS 13 makes its way into the world before we can know for sure if Apple’s succeeded a second time.
Apple promises things like Face ID will unlock 30 percent faster and that apps will launch twice as fast in iOS 13.
面容 ID 解锁速度提升 30 %，app 的启动速度提升达两倍。
DARK MODE
深色模式
Probably the single most anticipated change, and the biggest visual update Apple’s made to iOS since it introduced the current software design in iOS 7, iOS 13 is finally offering a true, system-wide dark mode.
All of Apple’s first-party apps are supported, and even notifications and the dock get new dark hues to go with it.
全新的深色配色方案可应用于整个系统和所有的原生 app。
hue
1）表示“颜色；色调；色度”，英文解释为“a colour or type of colour”，如：a golden hue 一种金黄色调；
2）表示“观点，看法”英文解释为“a type of opinion, belief etc”，短语：of every hue/of all hues (= of many kinds) 意思是“各种各样的”，如：opinions of every hue 形形色色的见解。
REMINDERS
提醒事项
Long overdue for an update, Apple is redoing the Reminders app entirely in iOS 13, adding new “Today,” “Scheduled,” “Flagged,” and “All” filtering options for sorting your tasks, along with a whole new visual look. Apple’s also pushing big AI integration here — you can type and Reminders will automatically suggest when you’d like to be reminded, and you’ll be able to tag contacts and be reminded when you open up their thread in Messages.
Also gone is the weird, paper-like texture that had been a mainstay of the old skeuomorphic iOS design since the original version of iOS.
提醒事项换上全新外观，让你以智能方式创建和编辑提醒事项，同时能够以更多不同方式整理和追踪。快速工具栏让你可以轻松添加时间、日期、位置和标记，或者添加附件。提醒事项与信息 app 更深入整合，可在提醒事项中轻松标记某人，当用户与被标记的人互发信息时，相关提醒事项就会自动显示。
overdue
表示“早该发生的；早该完成的；期待已久的”，英文解释为“something that is overdue should have happened or been done a long time ago”举个🌰：
We welcome this announcement and think it’s long overdue.
我们欢迎这个声明，并且对此期待已久。
skeuomorphic
skeuomorphic /ˌskjuːəˈmɔː(r)fɪk/ 表示“拟物化的（设计）”，Skeuomorphism is where an object in software mimics its real world counterpart. The “trash can” is, perhaps, the most recognizable skeuomorphic object.
UPDATES TO APPLE MAIL, NOTES, AND SAFARI
邮箱、备忘录、SAFARI浏览器
Apple’s also tweaking a few of its core applications on iOS 13. Apple Mail is set to get new desktop formatting. Safari is getting per-website preferences, and Notes is getting a new gallery view for looking at all your notes at once.
备忘录 app 现在有了全新的图库视图。
tweak
1）表示“对（机器、汽车或系统）作小小的改进”，英文解释为“to make small changes to a machine, vehicle, or system in order to improve the way it works”举个🌰：
Maybe you should tweak a few sentences before you send in the report.
报告交上去之前，有几个句子你也许应该修改一下。
2）表示“扭；扯；拧”，英文解释为“If you tweak something, especially part of someone's body, you hold it between your finger and thumb and twist it or pull it.”举个🌰：
He tweaked Tom's ear roughly.
他粗暴地扯汤姆的耳朵。
APPLE MAPS
Apple is completely redoing Apple Maps with iOS 13. The company says that it’s rebuilt the app from the ground up, with more comprehensive map data and a new mode that’s... basically just Google Street View. The new map will be available in select cities and states to start, and will roll out across the US by the end of 2019 and internationally in 2020.
from the ground up
表示“从头开始；彻底”，英文解释为“From the first step through to completion; entirely. From the beginning; starting with the basics, foundation, or fundamentals.”
PRIVACY
As is expected for Apple, privacy is a big part of the announcement here: now, you can choose to give your location data to an app “just once,” preventing it from constantly being able to ping your location when you’re using it.
Apple is also launching a new “Sign in with Apple” feature, which it’ll be making available to developers for logging into apps and services. Users will be able to log into Face ID and create a new account for a service “without revealing any personal information.”
NEW PHOTO AND VIDEO EDITING TOOLS
为照片 app 带来轻松浏览与强大编辑工具
Apple’s adding a new editing interface to iOS for photos — and for the first time, videos. You’ll be able to edit brilliance, highlights, shadows, contrast, saturation, white balance, sharpness, definition, vignette, and noise reduction on your content. And for videos in particular, you’ll finally be able to rotate them directly on the device.
saturation
表示“饱和度”，英文解释为“the degree to which sth is absorbed in sth else, expressed as a percentage of the greatest possible”。
vignette
英文解释为“a small illustration or portrait photograph which fades into its background without a definite border.” 照片处理的一种效果，中文不知道叫什么？
The Photos app is also getting a new UI, which will use machine learning to remove duplicates and weird clutter like screenshots for easy browsing.
利用设备端的机器学习功能，照片 app 会从图库中精选并突出显示最佳照片，自动隐藏杂乱内容和相似的照片，为你展示过去一天、过去一个月或过去一年发生的重大事件和活动。
clutter
表示“杂乱，凌乱；杂乱的东西”，英文解释为“a lot of objects in) a state of being untidy”举个🌰：
Sorry about the clutter in the kitchen.
对不起，厨房里杂乱不堪。
EXTERNAL STORAGE
外部存储
Finally, iOS will be able to pull files from SD cards and USB flash drives to import into the Files app.
文件 app 现在可与 iCloud Drive 共享文件夹，更可访问 SD 卡和 USB 闪存等外部存储设备上的文件。
iOS 13 will be available to iPhone devices (starting with the iPhone 6S, meaning that iPhone 5S and iPhone 6 users will be left behind). A developer preview will go live today following the keynote, with a public beta program later this month.
iOS 13 开发者预览版即日起向 Apple 开发者计划会员提供，公众测试计划将于下月晚些时候向 iOS 用户提供。
