iOS 场景无法加载任何图像
iOS Scene can't load any images
这类似于（但不是重复的，请阅读）：
我有一个加载其他元素（例如文本字段、标签等...）的场景，但每个图像都抛出“无法加载...从带标识符的捆绑包中的笔尖引用的图像”警告从上面的问题。
尝试所有答案后，我注意到其中一张图片在不同场景中加载正常。我尝试循环浏览已知的好图像，但错误仍然存在。
所以虽然前面的问题假设警告是正确的，以表明图像及其引用方式存在问题；我的问题似乎有所不同。场景的某些方面使其无法引用其任何图像。
我用的是单分镜，其他场景没有这个问题。唯一不同的是我正在尝试使用“模态呈现”segue，尽管我从与其他视图控制器相同的代码启动：
guard let alert = createPopUp(titled: Labels.Alerts.netError,
message: Labels.Alerts.aErrorMsg,
actions: [emptyDone]) else { return }
present(alert, animated: animated)
我在这里修改vc...
/// This method creates a custom view controller as an alternative to default alert view.
///
/// - Parameter title: The title text for alert view.
/// - Parameter message: The message text for alert view.
/// - Parameter needsTextField: If true a text input field is shown.
/// - Parameter actions: The actions to use when buttons are tapped.
func createPopUp(titled title: String, message: String, needsTextField: Bool = false, actions: [CustomAlertAction]? = nil) -> UIViewController? {
let storyboard = UIStoryboard(name: ElId.VCs.main, bundle: Bundle.module)
guard let vc = storyboard.instantiateViewController(withIdentifier: ElId.VCs.alert)
as? AlertViewController else { return nil }
vc.titleText = title
vc.messageText = message
vc.showField = needsTextField
if let actions = actions {
if actions.count < 2 {
let action = actions.first
vc.centerAction = action ?? CustomAlertAction(type: .cancel, action: nil)
} else {
vc.leftAction = actions[0]
vc.rightAction = actions[1]
}
} else {
vc.centerAction = CustomAlertAction(type: .cancel, action: nil)
}
return vc
}
是什么导致场景无法加载任何图片？
我的 ViewController 找到了，图像显示在属性检查器中，整个资产文件都被定位了，我在下面的情节提要中包含了图像视图的屏幕截图。我已经擦除项目，重新启动，renamed/reloaded 图像并循环到其他人。使用 Xcode 13.3.1。这是场景的来源：

编辑：
尝试删除 segue，但它仍然发生。
创建了一个只有一个场景的新项目，给它一个按钮来触发创建弹出窗口，将我的场景和此处显示的代码粘贴到项目中，一切都按预期工作。尝试将场景重新粘贴到我的原始项目中，但仍然失败。删除派生数据并再次尝试重新添加所有文件...仍然有问题！！！！
如有任何帮助，我们将不胜感激。
这里是VC...

问题涉及使用 Swift 包管理器。
我将大部分情节提要移到了 Swift 包中，但在应用程序中保留了原始的 main.storyboard，因为我还没有找到完全摆脱它的方法，只能依赖 Swift 包中的电路板。
因此，该应用程序在不同时间从我的应用程序中的故事板调用场景（它也有资产），而在其他时候它从包中的故事板调用场景（没有访问权限）到资产）。
如果我在实例化时以编程方式设置图像或使用 nil 来引用包，它可以工作，但在这种情况下它是“正确”完成的，但失败了，因为我还没有迁移图像资产。
将它们放入包中，现在可以使用了！！
这类似于（但不是重复的，请阅读）：
我有一个加载其他元素（例如文本字段、标签等...）的场景，但每个图像都抛出“无法加载...从带标识符的捆绑包中的笔尖引用的图像”警告从上面的问题。

编辑：
尝试删除 segue，但它仍然发生。
创建了一个只有一个场景的新项目，给它一个按钮来触发创建弹出窗口，将我的场景和此处显示的代码粘贴到项目中，一切都按预期工作。尝试将场景重新粘贴到我的原始项目中，但仍然失败。删除派生数据并再次尝试重新添加所有文件...仍然有问题！！！！
如有任何帮助，我们将不胜感激。
这里是VC...

问题涉及使用 Swift 包管理器。
我将大部分情节提要移到了 Swift 包中，但在应用程序中保留了原始的 main.storyboard，因为我还没有找到完全摆脱它的方法，只能依赖 Swift 包中的电路板。
因此，该应用程序在不同时间从我的应用程序中的故事板调用场景（它也有资产），而在其他时候它从包中的故事板调用场景（没有访问权限）到资产）。
如果我在实例化时以编程方式设置图像或使用 nil 来引用包，它可以工作，但在这种情况下它是“正确”完成的，但失败了，因为我还没有迁移图像资产。
将它们放入包中，现在可以使用了！！
