iOS 13 brought out a few control center tweaks, including a feature that lets you connect Wi-Fi networks and Bluetooth accessories around you without having to go into Settings and push you through the menus to select a nearby wireless network or device.
In iOS 12 and older, it was not possible to select Wi-Fi networks or Bluetooth accessories from the overlay of the control center. IOS 13 has changed behavior by introducing interactive Wi-Fi and Bluetooth panels into the Control Center interface.
The practical addition was briefly mentioned by Craig Federighi, Apple's Senior Vice President of Software Engineering, during the June 3 keynote address of the Worldwide Developers Conference 2019 held at the San Jose McEnery Convention Center in San Jose, California.
