iOS Simulator not working

Hi! I was trying to follow the Epic’s official guide on this: Using the Xcode iOS Simulator with Unreal Engine projects. | Unreal Engine 5.3 Documentation

I am using UE 5.3.2 (launcher version). I followed all the steps of the tutorial, and got the following issue:

ld: library not found for -l/Users/Shared/Epic Games/UE_5.3/Engine/Source/ThirdParty/BLAKE3/1.3.1/lib/IOS/Simulator/libBLAKE3.a

I’ve tried removing all the re-generated data (Saved, Intermediate, Derived Data Cache, Binaries + .xcworkspace and .sln files) - the issue is the same. Tried to launch it direclty on the simulator without quick launching on physical device - no help from that.
Did anyone manage to launch it?

I had the same issue -
The release version of UE5.3 does not include the BLAKE3 simulator binaries (and other required assets). It’s actually written in the Prerequisites section in the documentation,
I also missed it :slight_smile:
I was able to utelize the simulator with the UE5 source code from the git repo…
Try to recreate project files, rebuild engine and game.
