# NSWindow.Level

The standard window levels in macOS.

## Declaration

```swift
struct Level
```

## Discussion

Discussion The stacking of levels takes precedence over the stacking of windows within each level. That is, even the bottom window in a level will obscure the top window of the next level down. Levels are listed in order from lowest to highest. These constants are mapped (using #define statements) to corresponding elements in CGWindowLevelKey.
