Check your storyboard: All the IBAction, IBOutlet connected and with their current names? It's actually happens when problem with iboutlets
检查您的故事板：所有 IBAction、IBOutlet 都已连接并使用它们当前的名称？它实际上发生在 iboutlets 出现问题时

If you just updated to Swift 4and have issues running your app on iOS 11 device or simulator, maybe you have the same issue I had with the UIVisualEffectView, and specifically with adding subviews to it.
如果您刚刚更新到Swift 4并且在 iOS 11 设备或模拟器上运行您的应用程序时遇到问题，那么您可能遇到了与我相同的问题UIVisualEffectView，特别是在向其添加子视图方面。
苹果的文档说：
Add subviews to the contentView and not to UIVisualEffectView directly.
将子视图添加到 contentView 而不是直接添加到 UIVisualEffectView。
Basically, instead of adding subviews directly to the UIVisualEffectView, add them to its .contentView.
基本上，不是将子视图直接UIVisualEffectView添加到.contentView.
Example:
例子：
// create UIVisualEffectView
let blackBlur = UIVisualEffectView(effect: UIBlurEffect(style: .dark))
// adding a subview - this worked on iOS 10 - crashes the app on iOS 11
blackBlur.addSubview(someView)
// this works on both iOS 10 and iOS 11
blackBlur.contentView.addSubview(someView)
I hope this helps someone since it took me a while to figure this one out.
我希望这对某人有所帮助，因为我花了一段时间才弄明白。

If anyone is running into this problem make sure that you
如果有人遇到此问题，请确保您
- Go to Main.storyboard
- RIGHT click on the yellow box icon (view controller) at the top of the phone outline
- DELETE the outlet(s) with yellow flags.
- 转到 Main.storyboard
- 右键单击手机轮廓顶部的黄色框图标（视图控制器）
- 删除带有黄色标志的插座。
What happens in instances like this is you probably named an action, then renamed it. You need to delete the old name and if that was the only issue will start right up in simulator!
在这种情况下会发生什么是你可能命名了一个动作，然后重命名了它。您需要删除旧名称，如果这是唯一的问题，将在模拟器中立即启动！
NOTE:most of the time this happens because of wrong connection so double check and make sure all outlet connections are correct.
注意：大多数情况下发生这种情况是因为连接错误，因此请仔细检查并确保所有插座连接正确。

If you are using Firebase and have this problem when you upload be careful with the key value. The keys should not include '#' or '%' or etc. I just deleted and worked fine.
如果您使用 Firebase 并在上传时遇到此问题，请注意键值。键不应包含“#”或“%”等。我刚刚删除并且工作正常。

The raising method is setValue:forKey:, which is called after a table view cell was dequeued. Apparently in the MealTableViewController.
提升方法是 setValue:forKey:，它在表视图单元出列后调用。显然在 MealTableViewController 中。
Check your table view cells XIB, there might be an IBOutlet remaining with a wrong name, or maybe a property set with the wrong name.
检查您的表格视图单元格 XIB，可能还有一个名称错误的 IBOutlet，或者可能是一个名称错误的属性集。
