The arm64e architecture is used on the A12 chipset, which is added in the latest 2018 iPhone models (XS/XS Max/XR). The code compiles to ARMv8.3, which brings support for new features. Namely:
- Pointer authentication
- Nested virtualization
- Advanced SIMD complex number support
- Improved Javascript data type conversion support
- A change to the memory consistency model
- ID mechanism support for larger system-visible caches
The A12 features an Apple-designed 64-bit ARMv8.3-A six-core CPU
Read more about the architecture here as well:
To test arm64e with an app, update the Architectures setting in Build Settings. More details at .
Note that if you have CocoaPods dependencies, all of the Pods build targets must be similarly changed.
If any of the CocoaPods dependencies are binary instead of source pods, make a request to the vendor like
arm64 vs arm64e
Both are ABIs (lower level APIs) which compile to instructions (defined by an ISA/ instruction set architecture). arm64e is used on Mac M1's and iPhones. The differences between them are the points in Giovanni's answer.
