The apple has added some security features in iOS 12 too. One of them is USB Accessories, which restricts the use of USB Accessories when your iPhone hasn’t been unlocked for one hour. So if you haven’t unlocked the iDevice for more than an hour and you are trying to connect to a computer, then it will ask you to unlock the iPhone. After unlocking the iOS device when you connect using a lightning cable to Mac or Windows PC then only you can access USB data.
There are several problems you have to face in order to increase the security of your iPhone.
Once you disable USB Accessories, you can’t sync iTunes without entering the passcode of iPhone if your iPhone is locked for more than one hour.
If you are habituated to put your iOS device in charge anywhere like in Car or Charging accessories, then your experience will be interrupted by this security feature. Thankfully, there is no need to unlock iPhone when you are charging using Apple’s USB charging adapter.
How to access USB data on iPhone: Enable/ Disable USB accessories Access in iOS 12

Step 2: So if you have iPhone X then tap on “Face ID & Passcode” and for other iPhone/iPad tap “Touch ID & Passcode”.

Sometimes it may be possible that USB Accessory isn’t recognized by the device even after unlocking it. In that case, you should disconnect and reconnect the accessory from the iPhone.
Unfortunately, if your iPhone is stolen, then there are no chances that any hacking tool can collect the data stored in your device without unlocking it. This is iOS 12 for you!
