Can't use predefined template functions

Good Day!
I have child class of UAnimNotifyState and overwrite NotifyTick function using function of Utils class:

#pragma once

class Utils
{
public:
	template<typename T>
	static T* GetPlayerComponent(AActor* PlayerPawn)
	{
		if (!PlayerPawn) return nullptr;

		const auto Component = PlayerPawn->GetComponentByClass(T::StaticClass());
		return Cast<T>(Component);
	}
};

However compiling fails because this class is not initialized:
error C2027: use of undefined type ‘Utils’

code of overwritten function:

#include "Animations/SwingNotifyState.h"
#include "Character/BaseCharacter.h"
#include "Utils.h"
#include "Character/Components/WeaponComponent.h"
#include "Weapons/Melee/BaseMeleeWeapon.h"

void USwingNotifyState::NotifyTick(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation, float FrameDeltaTime, const FAnimNotifyEventReference& EventReference)
{
	if (const auto Actor = MeshComp->GetOwner())
	{
		if (auto WeaponComponent = Utils::GetPlayerComponent<UWeaponComponent>(Actor))
		{
			auto CurWeapon = WeaponComponent->GetCurrentWeapon();
			if(CurWeapon->IsA(ABaseMeleeWeapon::StaticClass()))
			{
				CurWeapon->SwingWeapon();
			}
		}
	}
	Super::NotifyTick(MeshComp, Animation, FrameDeltaTime, EventReference);
}

Thanks in advance

i think you just get rid of Utils::

because you defined the function in your header

You can’t use outside functions without class reference
