iOS 18 will be compatible with the iPhone XR, and thereby also the iPhone XS and iPhone XS Max models with the same A12 Bionic chip, according to a post on X today from a private account with a proven track record of sharing build numbers for upcoming iOS updates.
The post was spotted by MacRumors contributor Aaron Perris, and it has since been deleted. However, this was likely because the account prefers to keep a low profile, and many of its previously-deleted posts contained accurate information.
If this rumor is accurate, iOS 18 would be compatible with the same iPhone models as iOS 17:iPhone 15
