title: AActor *UactorComponent::GetOwner const - pointer to incomplete class type is not allowed
body: <p>I'm new to UE4 development and I've followed Udemy's Unreal Engine Development course. I have created a new Component on an Actor, named PositionReporter with header PositionReporter.h</p>
  
  <pre><code>#pragma once
  
  #include "CoreMinimal.h"
  #include "Components/ActorComponent.h"
  #include "PositionReporter.generated.h"
  
  
  UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
  class BUILDINGESCAPE_API UPositionReporter : public UActorComponent
  {
      GENERATED_BODY()
  
  public: 
      // Sets default values for this component's properties
      UPositionReporter();
  
  protected:
      // Called when the game starts
      virtual void BeginPlay() override;
  
  public: 
      // Called every frame
      virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
  };
  </code></pre>
  
  <p>and code in PositionReporter.cpp being</p>
  
  <pre><code>#include "PositionReporter.h"
  
  // Sets default values for this component's properties
  UPositionReporter::UPositionReporter()
  {
      // Set this component to be initialized when the game starts, and to be ticked every frame.  You can turn these features
      // off to improve performance if you don't need them.
      PrimaryComponentTick.bCanEverTick = true;
  
      // ...
  }
  
  
  // Called when the game starts
  void UPositionReporter::BeginPlay()
  {
      Super::BeginPlay();
  
      FString t = GetOwner()-&gt;GetActorLabel();
  
      UE_LOG(LogTemp, Warning, TEXT("Position Reporter reporting for duty on %s"), *t);
  
  }
  
  
  // Called every frame
  void UPositionReporter::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
  {
      Super::TickComponent(DeltaTime, TickType, ThisTickFunction);
  
      // ...
  }
  </code></pre>
  
  <p>As you can see, I am now trying to call the GetName function on the Pointer to the AActor retrieved through GetObject().</p>
  
  <p>However, as soon as I type "GetObject()->" no autocomplete pops up (as it does in the video) and when I add "GetName()" manually, I get the compiler error "pointer to incomplete class type is not allowed".</p>
  
  <p>What am doing wrong? Am I missing an import or so? I already compared my code to Ben's git repo but can't find any differences. I am on unreal editor 4.16.0!</p>
  
  <p>I noticed another strange thing: When I compile everything from Unreal Engine Editor, it compiles and runs fine. But when I compile it with VS 2017 I get the error, and I also dont get the Autocomplete, which is a real bummer. What am I missing?</p>
