Before Xcode 26, there was a plus button besides the status bar (the bar that says "Build Succeeded", "Fnished running...", "Indexing...", etc).
This button could be used to add new views to storyboards, search for SF symbols, add code snippets and so on. It would show a popup window like this:
In Xcode 26 beta, there are no buttons besides the status bar.
The only "+" button I see is for adding new tabs.
How can I access that popup window in the second screenshot in Xcode 26?
The popup window is called the "Library".
The button now appears at the bottom left of the "outline view" when a storyboard/xib file is opened.
Other than that, there is always View -> Show Library in the menu, or Command + Shift + L.
