Today, Apple launched the first public beta version of iOS 13.4. Compared with previous updates, this new version still adds many features.
In the latest iOS 13.4 public beta, Apple has modified this design. The mail toolbar returns to the iOS 12 design, including four buttons: delete, move, flag and reply. At the same time, the new system also supports iCloud cloud disk folder sharing, which is also a feature that many iPhone users have been waiting for.
In iOS 13.4, Apple has added 9 new stickers, including shocked faces, loving faces, eye rolls, etc., and a new Shazam It function has been added to the Shortcuts App.
In addition, the iOS 13.4 system also includes the CarKey API, which allows users to use iPhone and Apple Watch to unlock, lock and start the vehicle.
According to internal system documents, the CarKey function is compatible with NFC-enabled vehicles. Users only need to bring their iPhone close to the vehicle to unlock it. Face ID verification is not required. The entire process is similar to the iPhone NFC bus card. This also means that the iPhone can be used to unlock the vehicle when it is out of battery.
