Solution: iOS packaging error for PhysX library

Development Programming & Scripting
1

Unreal 4.27.2 source code version + Rider 2023.1 + MacbookPro 2023(M2 Max) + macOS Ventura 13.3.1(a).

When we use the PhysX library, two typical errors are as follows:

UATHelper: Packaging (iOS):   Undefined symbols for architecture arm64:
UATHelper: Packaging (iOS):     "PxCreateCooking(unsigned int, physx::PxFoundation&, physx::PxCookingParams const&)", referenced from:

UATHelper: Packaging (iOS):   fatal error: 'PhysXSDKVersion.h' file not found
UATHelper: Packaging (iOS):   #include "PhysXSDKVersion.h"
UATHelper: Packaging (iOS):            ^~~~~~~~~~~~~~~~~~~
PackagingResults: Error: 'PhysXSDKVersion.h' file not found

Solution:

Remove the comment of "PhysX3Cooking{0}" in the ios part of PhysX.Build.cs.

// before
		else if (Target.Platform == UnrealTargetPlatform.IOS)
		{
			string[] PhysXLibs = new string[]
				{
					"LowLevel{0}",
					"LowLevelAABB{0}",
					"LowLevelCloth{0}",
					"LowLevelDynamics{0}",
					"LowLevelParticles{0}",
					"PhysX3{0}",
					"PhysX3Common{0}",
					//"PhysX3Cooking{0}", // not needed until Apex
					"PhysX3Extensions{0}",
					"SceneQuery{0}",
					"SimulationController{0}",
					"PxFoundation{0}",
					"PxTask{0}",
					"PxPvdSDK{0}",
					"PsFastXml{0}"
				};


// after
		else if (Target.Platform == UnrealTargetPlatform.IOS)
		{
			string[] PhysXLibs = new string[]
				{
					"LowLevel{0}",
					"LowLevelAABB{0}",
					"LowLevelCloth{0}",
					"LowLevelDynamics{0}",
					"LowLevelParticles{0}",
					"PhysX3{0}",
					"PhysX3Common{0}",
					"PhysX3Cooking{0}", // not needed until Apex
					"PhysX3Extensions{0}",
					"SceneQuery{0}",
					"SimulationController{0}",
					"PxFoundation{0}",
					"PxTask{0}",
					"PxPvdSDK{0}",
					"PsFastXml{0}"
				};
