Privacy iOS 13 changes the handling of location data. When an app requests access to location, the user chooses whether to grant access whenever they are using the app, never, or only once. The user will receive similar prompts for background location access, and when an app requests access to Bluetooth or Wi-Fi (which may also be used for non-consensual location tracking). In August 2019, it was reported that beginning in April 2020, the PushKit API for
VoIP would be restricted to internet telephone usage, closing a "loophole" that had been used by other apps for background data collection.
User interface A system-wide
dark mode allows users to enable a light-on-dark color scheme for the entire iOS and iPadOS user interface, all native applications, and supported third-party apps. It can be manually turned on or set to automatically switch between light and dark modes based on the time of day. The volume indicator was redesigned, replacing the larger, centered overlay with a slimmer bar shown vertically near the volume keys in portrait orientation, or at the top in landscape. The bar can also be manipulated directly. The card UI elements from
Apple Music,
Apple Podcasts, and
Apple Books has been implemented system-wide, being an option for third-parties to use in their apps.
Siri Siri uses a software-generated voice called "Neural TTS", intended to sound more natural than previous versions that use clips of human voices. Siri also became more functional and new sound control is available. The Siri Shortcuts app is installed by default. Siri also uses HomePod to learn and recognize voices of different people. It is also possible for Siri to automatically read incoming messages aloud on AirPods.
Keyboard The QuickType virtual keyboard features QuickPath, allowing the user to swipe their finger across the keyboard to complete words and phrases. This functionality was previously exclusively available via third-party keyboard applications such as
SwiftKey,
Adaptxt,
Gboard, or
Swype. Emoji stickers have been included on the
emoji keyboard and can be used wherever regular emoji can be. The blue text cursor can be moved around text fields by pressing and holding to pick it up and move it. Many new options for text selection have also been added: double-tapping a word will select it, triple-tapping selects a sentence, and quadruple-tapping a paragraph selects it.
Sign in with Apple A new
single sign-on service known as "
Sign in with Apple" is integrated with iOS 13, and allows users to create accounts for third-party services with a minimal amount of personal information. Users may optionally generate a
disposable email address for each account, improving privacy and anonymity, and reducing the amount of information that can be associated with a single email address. The iOS
human interface guidelines also state that Sign in with Apple should be given prominence above any other login provider in application interfaces.
Performance iOS 13 contains several performance improvements.
Face ID unlocks the
iPhone X,
XS/
XS Max, and
XR up to 30% faster than on iOS12. A new file format makes app downloads as much as 50% smaller, app updates as much as 60% smaller, and app launches up to twice as fast. iOS 13 has a feature to limit the battery charging percentage to 80%. Keeping the battery percentage more centered instead of complete charges and discharges reduces strain onto the battery. This reduces the battery aging of the
lithium-ion battery and extends its lifespan.
Haptics iOS 13 introduced a new Core Haptics framework. Prior to iOS 13, apps could only provide the default haptic patterns. Core Haptics gives developers more fine-grained control over the iPhone's Taptic Engine, including synchronized audio, allowing apps to provide customized haptic and audio feedback. This feature is only available on iPhone 8 or newer. It is also not supported on the iPod Touch due to the lack of a haptic motor in those devices.
External storage iOS 13 introduced the ability to use external USB drives in Files. Previously external storage was supported in Photos. Although primarily designed for thumb drives and hard drives, a wide variety of USB disk devices will work, thanks to the iOS's support of the SCSI subclass of USB Mass Storage. Native SCSI disk devices will work as well, when used with a SCSI to USB adapter.
Exposure Notification API On May 20, 2020, Apple released iOS 13.5, which includes the Exposure Notification API that provides access to the
(Google/Apple) Exposure Notification System that Apple have developed jointly with Google. This is provided to support
digital contact tracing which came to light during the
COVID-19 pandemic.
ARKit 3 ARKit 3 was released as a part of iOS 13 and brought new features, such as People occlusion, which allowed AR objects to be in front or behind people in a more realistic way. New features were restricted to devices with A12 processors and newer – like
iPhone XS,
iPhone XR, and the 2018
iPad Pro. Other features of ARKit 3 were multiple face tracking and collaborative sessions.
ARKit 3.5 Released with the 2020 iPad Pro, ARKit 3.5 vastly improved positioning in virtual environments due to new anchors and use of data from a LiDAR scanner. It also improved its motion capture and people occlusion.
Other changes The version of iOS for iPad devices was renamed iPadOS, reflecting the precedence for the OS to include additional features intended primarily for use on tablets. iOS13 adds official support for the
Sony DualShock 4 and the
Microsoft Xbox One controller. iOS13 also adds support for wireless audio sharing for
AirPods and certain
Beats headphones. A new multi-select gesture is available in supported applications such as Files and Mail. Multiple items, such as files or emails, can be quickly selected by dragging two fingers over the desired items. ==App features==
