You can browse and insert Library Symbols via the Insert Window or the Insert menu 
.
To use the Insert Window, open it by pressing C or choosing Window > Insert from the menu bar. In the window, you’ll see all of your enabled Libraries in the left sidebar. Click on the Library 
you want to browse. You can also search for any Symbol using the search bar. From there, you can drag and drop any Symbol onto the Canvas.
You can also access Library Symbols from the Insert menu where, instead of the usual Symbols icon 
, they’ll have a link icon to show they’re part of a Library.
You’ll also find Library Symbols in the Inspector when you swap symbols.
How to edit Library Symbols
When you double-click a Library Symbol to edit, you’ll see you have a few options, depending on where the Library file has been added from.
Double-clicking to edit a Symbol that belongs to a Local Library or a Library in your Workspace will present the following options:
- Open in Library will take you to the original Library document so you can edit the Symbol’s Source. This will update the Library and any documents with instances of that Symbol.
- Unlink from Library will create a local version of the Symbol so you can edit its Source in your current document. This will mean you’ll no longer get updates to that symbol if the Library it originally came from gets updated.
If you’re trying to edit a Symbol that’s part of a Library on a shared Workspace you’ll see the following options:
- Open in Library will open the original Library document from your shared Workspace. Any changes made here will update the Library for your whole team and any documents with instances of that Symbol will reflect the changes.
- Unlink from Library will create a local version of the Symbol so you can edit its Source in your current document. This will mean you’ll no longer get updates to that Symbol if the Library it originally came from gets updated.
If you’re using a Library as part of a team, take extra care when editing Symbol Sources there. Everyone using that Library will receive any changes you make. You can star Library versions and anyone working with that Library will receive every change associated with the starred version. Unstarred versions won’t immediately send changes to Library users, so you can safely keep making changes without sending them to everyone until you’re ready. Learn more about Starred versions.
If the Symbol you want to edit belongs to a Third Party Library like the Apple iOS UI kit you’ll only have the option to Unlink from Library.
