The upcoming iOS 18.1 update allows users to change the primary email address associated with their Apple Account more easily.
In the current version of iOS, changing the Apple Account primary email is quite a hassle. To do so you need to first delete your primary email, add a new one and then go through the verification process again. Alternatively, users can set up alias emails that replace the name when sending over documents, but the main email can still be seen on occasion, which can be pretty awkward if you're still using your old "fun" email you made as a kid.
