After releasing updates for developers a few days ago, Apple today pushed the first public beta of iOS 13.4 and iPadOS 13.4.
There is evidence that iOS 13.4 supports CarKey which can turn iPhone into a car key.
In iOS 13, Apple has streamlined the toolbar of the Mail app into two buttons: Delete and Reply. Both buttons are located on the right side, and some users have indicated that they often make mistakes.
In the latest iOS 13.4 beta, Apple has modified this design, and the Mail toolbar is back to the iOS 12 design, including four buttons: delete, move, flag, and reply.
iOS 13.4 includes the CarKey API, which allows users to unlock, lock, and activate vehicles using iPhone and Apple Watch.
According to the internal documents of the system, CarKey is compatible with NFC-enabled vehicles. Users can unlock the iPhone by holding the iPhone close to the vehicle. Face ID verification is not required. It also means that iPhone can be used to unlock the car when it is out of power.
The pairing process requires the use of a wallet app, and the application of the vehicle manufacturer needs to be installed to complete the setup. After pairing, the CarKey will be in the wallet app and can be easily added to the Apple Watch.
Changelog:
Location Services: The iPhone/iPad will immediately display the corresponding authorization prompt when the application first requests "Always use Location Services" authorization.
Keyboard shortcuts: Keyboard shortcuts have been added to the Photos app on the iPad. In full-screen mode, the new shortcuts can be used to delete photos, copy photos, and enter editing mode.
iCloud folder sharing: iCloud folder sharing is a feature that Apple added for the first time when it showcased iOS 13 at WWDC and is now available.
CarPlay: "CarPlay" in iOS 13.4 beta adds support for new third-party navigation and call control.
Added multiple memoji expressions: There are 9 new memoji sticker options, including "shock" and so on.
CarKey API: A new API called CarKey exists in Apple iOS 13.4 beta, allowing users to unlock, lock and launch compatible cars using iPhone/Apple Watch.
New Mail App toolbar design: The options in the Mail App toolbar have been rearranged, and "Delete" is no longer next to "Reply", but on the opposite side. "Mark" and "folder" are in the middle.
Apple watchOS 6.2 update adds support for in-app purchases. Users can purchase the required functions directly in the watchOS app to access advanced content, digital goods, subscriptions and more.
