Using Multiple Workspace Windows
Create multiple workspace windows by choosing File > New > Window. Each window can be customized independently of the others.
For example,shows the storyboard editor in one window and running the view debugger in another.
Use tabs to implement multiple, workflow-specific layouts of the workspace window. Add tabs to a workspace window by choosing File > New > Tab, or by clicking the Add (+) in the tab bar. Click a tab to make it the active workspace window layout.
You can customize the name of a tab by double-clicking on the existing name. For example, in
ListDocumentViewController.swift. The name of the next tab is customized to
Debugger. The name of the third tab is also customized and shows a storyboard. The final tab shows a view debugger.
Create a new workspace window from a tab by dragging it out of the tab bar. Move the tab to a different workspace window by dragging it into a window.
