Why Can't I Add Music to My iPhone iOS 12?
There are lots of different reasons why you may not be able to sync music with your iPhone:
1. You have a hardware failure
It could be that somewhere along the line, your hardware isn’t able to send the information to your iPhone properly. This could be an issue with your USB cable, your computer’s USB port, or your iPhone itself.
2. Your iPhone is out of space
Of course if your iPhone doesn’t have enough room for your songs, it won’t be able to take new ones. If the sync only partially worked, this may be the culprit. Partial syncing may also cause iTunes cache on iPhone.
3. You need to update iTunes
Sometimes iTunes can act weird if it hasn’t been updated. Make sure that everything is up to date before you try syncing. Or you may need to completely uninstall iTunes and related software components and reinstall.
4. You need to update iOS
Similarly, if your version of iOS is too old, this may cause compatible problems.
5. You have a network problem
Is your WIFI network running properly? Any problems with the network may cause you to be unable to sync.
Your iCloud Music Library is interfering with the syncing
Sometimes if your iCloud Music Library is turned on, you may be unable to sync via iTunes properly. Go to "General > Music > iCloud Music Library" on iPhone to ensure.
