How do you dock the interface builder to xcode? for some reason, it is in its own window
unable to dock interface builder.
Which version Xcode are you using?
From the docs:
Access your Interface Builder objects from a dock or the canvas. The dock is the column on the left side of the interface builder editor window, and the canvas is the design area on the right. The dock lists the objects contained in the user interface file. The outline view in the dock, shown in the following screenshot, displays all the objects nested inside higher-level objects. The canvas is where you lay out these objects in your app’s user interface.
