Say you need a dumb data container for usage in either Blueprints or C++.

Does your container need functions? Use a UCLASS UOBJECT, otherwise, use USTRUCT.

UCLASS:

1. From the editor, create a new C++ class, Show All, choose UObject
2. Set the following specificers for UCLASS and UPROPERTY in the header file:

UCLASS(BlueprintType)
class x_API UMyObject: public UObject
{
	GENERATED_BODY()
	
public:
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	MyProperty* Property;	

	UFUNCTION(BlueprintCallable)
	void MyFunction();

USTRUCT:

1. Create an Empty C++ class from the editor
2. Edit the header file:

USTRUCT(BlueprintType)
struct FMyStruct
{
	GENERATED_STRUCT_BODY()
	
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	MyProperty* Property;
