# LCEssentials — Extensions

Foundation, value-type, string, collection, numeric, date, and crypto helpers, plus
the `LCEssentials` namespace itself. UIKit extensions live in
[UIKit.md](UIKit.md); SwiftUI helpers in [SwiftUI.md](SwiftUI.md).

Every section is a collapsible block — click a heading to expand it.
