In Xcode 10 the Library, where you access things like code snippets and user interface elements, is no longer in the lower right portion of the project window. The button to access the Library has been moved to the right side of the toolbar, next to the buttons to show the various editors.
Click the Library button to open the Library in a separate window. Option-clicking the Library button keeps the window open, which helps a lot when you’re building your app’s user interface.
The specific library that opens depends on the file you’re currently viewing/editing. If you’re in a source code file, clicking the Library button will open the code snippets library. If you’re in a xib file or storyboard, clicking the Library button will open the object library that contains the UI elements.
