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
- iPhone 15 Plus
- iPhone 15 Pro
- iPhone 15 Pro Max
- iPhone 14
- iPhone 14 Plus
- iPhone 14 Pro
- iPhone 14 Pro Max
- iPhone 13
- iPhone 13 mini
- iPhone 13 Pro
- iPhone 13 Pro Max
- iPhone 12
- iPhone 12 mini
- iPhone 12 Pro
- iPhone 12 Pro Max
- iPhone 11
- iPhone 11 Pro
- iPhone 11 Pro Max
- iPhone XS
- iPhone XS Max
- iPhone XR
- iPhone SE (2nd generation)
- iPhone SE (3rd generation)
The same source expects iPadOS 18 to drop support for iPad models with the A10X Fusion chip.
