Apple doesn’t announce how much RAM is included in iPhone 18 Pro models, but Woozad confirmed this information in the latest version of Xcode 27.
Here is the amount of RAM present in each new iPhone model:
- iPhone 18 Pro: 12 GB
- iPhone 18 ProMax: 12 GB
Xcode doesn’t yet support the iPhone Duo, but that device has the same A20 Pro chip as the iPhone 18 Pro models, so it should also have 12GB of RAM.
The iPhone 17 Pro models also have 12 GB of RAM, so there is no increase over the previous generation:
- iPhone17: 8 GB
- iPhoneAir: 12 GB
- iPhone 17 Pro: 12 GB
- iPhone 17 ProMax: 12 GB
Apple said the iPhone 18 Pro and iPhone 18 Pro Max will be available for pre-order starting Saturday, September 12 at 5 a.m. PT in the United States and many other countries. The devices are expected to launch the following week, on Friday, September 18.
