To add your iPhone to iTunes, connect it to your computer with a USB cable, open iTunes, and tap Trust on your iPhone if prompted. Your device should then appear in iTunes, where you can sync, back up, or manage your files.
If you want to add apps to your iPhone from a computer, the easiest way is to use the App Store directly on your iPhone. Apple no longer lets you install new apps through iTunes like before. If you already have apps downloaded on your computer or need to manage iPhone data, you can use tools like MobiKin Assistant for iOS to manage backups, transfers, and other iPhone content. For apps themselves, though, you’ll usually need to download them from the App Store on your device.
You can add a video on YouTube without going through iTunes on your iPhone by uploading it directly via your PC.

You can’t install apps onto an iPhone from iTunes anymore. Apple removed app management from iTunes in newer versions. To get apps on your iPhone, open the App Store on the device, search for the app, and tap Get or the download button. If you previously downloaded apps with the same Apple ID, you can find them under App Store > your profile > Purchased. If you’re using an older version of iTunes that still supports apps, you may be able to sync them through iTunes, but for most users today, the App Store is the way to go.
