Can't compile a C++ UInerface

Hi, two days ago I’ve posted the same question on answerhub without any result. So i dediced to repost it here.

I’m trying to create a interface in c++ that has to be visible in Blueprints so BP actors can use it to call functions of a C++ gamemode.
To create the interface i followed Rama’s guide on the wiki.

I ended up with this code:
.h (this was a UObject child class)


 #pragma once
 
 #include "GamemodeInterface.generated.h"
 
 UINTERFACE(Blueprintable)
 class UGamemodeInterface : public UInterface
 {
     GENERATED_UINTERFACE_BODY()    
 };
 
 class IGamemodeInterface
 {
     GENERATED_IINTERFACE_BODY()
 
//doen't compile even if I remove the tro function under this comment
 public:
 
     UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category = "Game Mode")
     void EnemyKilledCallback();
 
     UFUNCTION(BlueprintNativeEvent, BlueprintCallable,Category = "Game Mode")
     void PlayerKilledCallback();
 };

.cpp


 #include "UntillLight.h"
 #include "GamemodeInterface.h"
 
 void IGamemodeInterface::EnemyKilledCallback()
 {
 }
 
 void IGamemodeInterface::PlayerKilledCallback()
 {
 }
 
 UGamemodeInterface::UGamemodeInterface(const class FObjectInizializer& PCIP) : Super(PCIP)
 {
 }

When i try to compile this code I always get these errors but I can’t find what is the cause:


2>D:\Develop\Unreal Projects\UntillLight\Source\UntillLight\GamemodeInterface.cpp(14): error C2511: 'UGamemodeInterface::UGamemodeInterface(const FObjectInizializer &)': overloaded member function not found in 'UGamemodeInterface'
 2>  d:\develop\unreal projects\untilllight\source\untilllight\GamemodeInterface.h(11): note: see declaration of 'UGamemodeInterface'
 2>D:\Develop\Unreal Projects\UntillLight\Source\UntillLight\GamemodeInterface.cpp(15): error C2550: 'UGamemodeInterface::{ctor}': constructor initializer lists are only allowed on constructor definitions
 2>  UntillLight.cpp
 2>  UntillLight.generated.cpp
 2>ERROR : UBT error : Failed to produce item: D:\Develop\Unreal Projects\UntillLight\Binaries\Win64\UE4Editor-UntillLight.dll

I also tried to follow visual studio advice and I’ve added the constructor declaration as follows:
new .h


#pragma once

//#include "Object.h"
#include "GamemodeInterface.generated.h"

/**
 * 
 */
UINTERFACE(MinimalAPI,Blueprintable)
class UGamemodeInterface : public UInterface
{
	GENERATED_UINTERFACE_BODY()

	UGamemodeInterface(const class FObjectInizializer & inizializer);

};

class UNTILLLIGHT_API IGamemodeInterface
{
	GENERATED_IINTERFACE_BODY()

public:

	UFUNCTION(BlueprintNativeEvent, BlueprintCallable, Category = "Game Mode")
	void EnemyKilledCallback();

	UFUNCTION(BlueprintNativeEvent, BlueprintCallable,Category = "Game Mode")
	void PlayerKilledCallback();
};

Even this try ended up with a compile error:


2>D:\Develop\Unreal Projects\UntillLight\Source\UntillLight\GamemodeInterface.cpp(7): error C2664: 'UInterface::UInterface(const UInterface &)': cannot convert argument 1 from 'const FObjectInizializer' to 'const FObjectInitializer &'
2>  D:\Develop\Unreal Projects\UntillLight\Source\UntillLight\GamemodeInterface.cpp(7): note: Reason: cannot convert from 'const FObjectInizializer' to 'const FObjectInitializer'
2>  D:\Develop\Unreal Projects\UntillLight\Source\UntillLight\GamemodeInterface.cpp(7): note: No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

I’m running out of ideas to try what can I do?

Found the solution. I misspelled FObjectInitializer, I wrote FObjectIniZializer.
