Is iOS device support available in ANGLE? Is there an official build guide?

[jian chen]

Hi ANGLE team,

I'm currently integrating ANGLE into a standalone iOS application (outside of Chromium) and would like to clarify:

Does ANGLE officially support running on iOS devices (e.g., iPhone, iPad), not just the simulator?

If so, is there an official or recommended guide for building ANGLE for iOS real devices (arm64 target)?

Are there any required configurations to use ANGLE safely without Chromium (e.g., disabling PartitionAlloc)?

So far, I've managed to build ANGLE using the Chromium iOS GN build system, but when running on a real device, I encountered this runtime error:

[FATAL:partition_address_space.cc(79)] Check failed: false.

This seems related to PartitionAlloc not being properly initialized, which might be expected in Chromium but not in a standalone app.

Would appreciate any official guidance, or confirmation of:

iOS real-device runtime support

A minimal working GN args.gn or setup for building and integrating ANGLE on iOS

Whether standalone usage on iOS is a supported scenario, now or in future plans

Thank you for your time!

I built ios angle with these arguments. And it worked fine.
