Those who can’t get into mobile have their reasons, but one less reason now is traditional controller support as the iOS updates have given you access to native DualShock 4.
Along with iOS 13 comes iPad OS and tvOS13, all of which come with the same compatibility.
Not only that, you can enjoy streaming from any app compatible with PS4 remote play with the DualShock.
Apple has always been on the forefront, one way or another, when it comes to mobile gaming.
