If your iPhone is not showing up in iTunes, there are a few possible solutions. First, ensure that your iPhone is unlocked and on the home screen. Next, check that your computer and iPhone are both connected to the same Wi-Fi network. You may also try unplugging and reconnecting both your iPhone and your computer to the computer. If the problem persists, try restarting both your computer and iPhone. If none of these steps work, you may need to update your iTunes software or try using a different USB cable.
