## What's new?
- Added Android platform support to PhysX 5.1.
- New build preset `android-arm64-v8a` added. Initial support focused on 64-bit arm8 architecture with NEON SIMD instructions.
- Support for generating PhysX as either static or dynamic libraries.
- New android platform readme.
## Out of Scope
The following points are considered out of scope, they can be added in the future:
- Support for PhysX Snippets.
- Support for Omniverse Visual Debugger (OmniPVD) .
- Support for other architectures: arm7, x86, x86_64.
- Support for other SIMD instructions set: SSE.
## Known Errors/Limitations
- The name of the bin folder for android will appear as `bin\UNKNOWN`. **To fix this nVidia has to modify the CMakeModules package it's downloaded from packman when building PhysX** (NVIDIA-Omniverse#59). The file that needs to be modified is `GetCompilerAndPlatform.cmake`, adding the following lines to the `if` condition inside `GetPlatformBinName` function:
````
ELSEIF(TARGET_BUILD_PLATFORM STREQUAL "android")
SET(RETVAL "android.${ANDROID_ABI}")
````
- PhysX Systems that require a CUDA capable GPU are not supported in Android, for example particle system or cloth simulation.
## Testing
- Built PhysX 5.1 successfully on android in debug, checked, profile and release using `PX_GENERATE_STATIC_LIBRARIES` set to both true and false. The right output binaries were generated in `bin/android.arm64-v8a`
- Built cmake `install` target successfully. It generated the correct output for Android under `install/android-29` folder, only including necessary headers for Android.
- Runtime tested using `Open 3D Engine (O3DE)` with an early integration [branch](https://github.com/aws-lumberyard-dev/o3de/tree/PhysX5Support). The following video shows O3DE running PhysX 5.1 on Android.

## What's new?
- Added iOS platform support to PhysX 5.1.
- New build preset `ios64` added. Initial support focused on 64-bit arm8 architecture with NEON SIMD instructions.
- Support for generating PhysX as either static libraries or iOS frameworks.
- New iOS platform readme.
## Out of Scope
The following points are considered out of scope, they can be added in the future:
- Support for PhysX Snippets.
- Support for Omniverse Visual Debugger (OmniPVD) .
- Support for other architectures: 32-bit arm7
## Known Errors/Limitations
- The name of the bin folder for iOS will appear as `bin\UNKNOWN`. **To fix this nVidia has to modify the CMakeModules package it's downloaded from packman when building PhysX** (NVIDIA-Omniverse#59). The file that needs to be modified is `GetCompilerAndPlatform.cmake`, adding the following lines to the `if` condition inside `GetPlatformBinName` function:
````
ELSEIF(TARGET_BUILD_PLATFORM STREQUAL "ios")
SET(RETVAL "ios.arm_${LIBPATH_SUFFIX}")
````
- Python package used by packman is based on x86_64 architecture and generates the error `dyld[number]: missing symbol called` when run on an arm-based Mac. **To fix this nVidia has to add an ARM python package for mac into the packman scripts** (NVIDIA-Omniverse#60). As a temporary solution, use your system's python adding the environment variable `PM_PYTHON_EXT` before building (for example by adding `export PM_PYTHON_EXT="python3"` into your `.bash_profile` file).
- PhysX Systems that require a CUDA capable GPU are not supported in iOS, for example particle system or cloth simulation.
## Testing
- Built PhysX 5.1 successfully on iOS in debug, checked, profile and release using `PX_GENERATE_STATIC_LIBRARIES` set to both true and false. The right output binaries were generated in `bin/ios.arm_64`
- Built cmake `install` target successfully. It generated the correct output for iOS under `install/ios64` folder, only including necessary headers for iOS.
