💡 Pro tip for Swift developers: Not every SF Symbol is available across all iOS versions. A Image(systemName:) call might return nil on devices running an older version of iOS. Always check availability or provide fallbacks to avoid those mysterious missing icons.

This is an example of what I meant yesterday. If you use "text.document" and your app targets iOS 17 or earlier, Image(systemName:) returns nil on those older iOS versions. This also shows how important it is to test your apps on older iOS versions.
