Your phone is 60 GB out of 64 GB or ?Ok so now there is a different issue. Using iTunes, it asks if I want to update to iOS 13. If I select yes, it begins a local backup.
After a few minutes, the backup fails, saying there isn't enough space. Problem is, there is ~120 GB free on my mac, and my phone is only using about 60 GB. The phone also has a cloud backup from today.
I can't update via iTunes without a local backup apparently, and there's some kind of glitch there also.
