Pretty much as the tittle suggests. IOS 13 now supports controllers like the Xbox One & PS4 Dual shock natively. Does that now mean that Infinite Flight will be able to accommodate joysticks through the USB-C connectors found on 2018 iPad pros and USB-A to lightning connectors to older iPads and current iPhones?
UPDATE 1: @Hymenopus_Coronatus has confirmed that Xbox One Controllers do indeed work with Infinite Flight on the current iOS 13 Beta. This is exciting news!
@George_Anastasis has also confirmed that the PS4 DualShock controller works with Infinite Flight as well! Must be on iOS 13 Beta for this to work as well.
