CGWindowLevel
A level assigned to a window by an application framework.
Declaration
typealias CGWindowLevel = Int32Discussion
In macOS, application frameworks support the concept of multiple window levels (or layers). Window levels are assigned and managed by each individual framework.
Note that in an Aqua-compliant application, each document window exists in its own layer. As a result, windows created by different applications can be interleaved.
