Xcode更新后出现虚幻错误：PCH文件使用了不再支持的旧PCH格式

Question

所以我最近才将Xcode（不太确定这是否引起了问题）更新为版本10.2。当我在Unreal Engine 4版本4.21.2中编译代码时，它给了我这个错误。 “ PCH文件使用了不再支持的旧PCH格式”我能做些什么来解决它？

    UOpenDoor();

    void CloseDoor();

    // Called every frame

    UPROPERTY(EditAnywhere)
    float OpenAngle = -90.0f;

    UPROPERTY(EditAnywhere)
    ATriggerVolume* PressurePlate;

    UPROPERTY(EditAnywhere)
    float DoorCloseDelay = 1.f;

    float LastDoorOpenTime;

    float GetTotalMassOfActorsOnPlate();
    //UPROPERTY(EditAnywhere)
    //AActor* ActorThatOpens; //Pawn inherits from AActor
    AActor* Owner; //The owning door
    void FindPressurePlate();`enter code here`

};

我希望游戏可以编译到我的较新版本，实际结果游戏不能编译。
