My C++ code can be compiled in XCode successfully. And my UE project can be built successfully for release.
But if I click the button in editor for live-coding, it starts to compile and then failed with following error. It seems it cannot find the symbol of FMetalContext::GetCommandQueue()
CompilerResultsLog: [4/6] Compile [Apple] SceneVideoCapture.cpp
CompilerResultsLog: [5/6] Link [Apple] UnrealEditor-MacDemo-5615.dylib

I have added MetalRHI in my Build.cs
PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
PrivateDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "Slate", "RenderCore", "RHI", "RHICore", "Projects" });
if (Target.Platform == UnrealTargetPlatform.Mac)
{
PrivateDependencyModuleNames.AddRange(new string[] { "MetalRHI" });
PublicWeakFrameworks.Add("Metal");
AddEngineThirdPartyPrivateStaticDependencies(Target, "MTLPP");
string srcPath = Path.Combine( ModuleDirectory, "lib", "libipc.dylib");
string binariesDir = Path.Combine(GetUProjectPath(), "Binaries", Target.Platform.ToString());
File.Copy(srcPath, Path.Combine(binariesDir, "libipc.dylib"), true);
RuntimeDependencies.Add("$(BinaryOutputDir)/libipc.dylib", srcPath);
string libFile = Path.Combine( ModuleDirectory, "lib", "libfrida-gum.a");
PublicAdditionalLibraries.Add(libFile);
PublicIncludePaths.AddRange(new string[] { Path.Combine( ModuleDirectory, "lib") });
}
else
{
string srcPath = Path.Combine( ModuleDirectory, "lib", "ipc.dll");
string binariesDir = Path.Combine(GetUProjectPath(), "Binaries", Target.Platform.ToString());
File.Copy(srcPath, Path.Combine(binariesDir, "ipc.dll"), true);
RuntimeDependencies.Add("$(BinaryOutputDir)/ipc.dll", srcPath);
}
Why it only failed to link in editor model?
Thanks in advance
