USB-C Accessory with iOS 18
Hello, We have noted that our USB-C accessory now supplies power and data after a role-switch when it previously would initialize with supplying power to the iOS device, then move to just transferring data to the iOS device after a role-switch. The charging+data behavior is only seen when the accessory is connected to a USB-C based iOS device running iOS 18. Are there some updates in iOS 18 that would cause this behavior? We noted that the expected case occurs with USB-C devices running on the earlier versions (iOS 17 and below).
