如何解决重叠视图的问题？

Question

在我的应用程序中，有一个显示动画的函数：

func showAnimation() {
    let animatedViewController = AnimationViewController(name: "")
    animatedViewController.modalPresentationStyle = .overFullScreen
    animatedViewController.modalTransitionStyle = .crossDissolve
    self.present(animatedViewController, animated: true, completion: nil)
}

当应用程序在ViewDidload中启动时，启动了动画功能（ShowAnimation）和数据加载功能。问题在于，如果数据失败了数据，则应出现警报或全屏，但此时仍将显示动画。视图未显示，并且发生错误：

[演示]尝试在（uitabbarcontroller）上介绍（someviewController）（来自myApp.mainviewController），而演示正在进行。

我该如何修复？

有了一点了解，我以这种方式解决了问题：
我的错误显示了函数 -

    private func showFullScreenError(with error: Error,
         action: (() - void)? = nil, actionAfterDismiss:action: (() - void)? = nil) {
            
            let errorVC = ErrorFullScreenViewControllr(
            eeror = error,
            action = action,
            actionAfterDismiss: actionAfterDismiss)

    //This is where we check if our view is currently presenting anything else

            if let nowShowingVC = self.presentedViewController {

    //The most important thing here is that if you close the view not in a 
//completion, then the view will not have time to close before you try to open a new one.

            nowShowingVC.dismiss(animation: false) {
            self.present(errorVC,animated: true)
                } else {
                 self.present(errorVC,animated: true)
                }
              }
            }
