When you create a new project, it’s good to know that you don’t need to think about where to find some simple icons.
With iOS 13 Apple introduced SF Symbols. It’s a set of free, built-in icons that you can use in your project.
In SwiftUI, you can use them using Image with systemName constructor.
I didn’t find any solution to list them in Xcode without Storyboard. However, you can find the list of them on the website or on the GitHub page. I prefer using GitHub because the website says that there are 1584 symbols and on the GitHub, there are 1661 lines in the JSON file.
There are useful because you don’t need to create your own image of plus or bin icon.
