Toolbars - Bars - iOS - Human Interface Guidelines - Apple Developer
A toolbar appears at the bottom of a screen and contains buttons for performing actions relevant to the current view.
By default, a toolbar is translucent: It uses a background material only when content appears behind it, removing the material when the view scrolls to the bottom.
A toolbar hides when a keyboard is onscreen.

⇒ 디폴트로 반투명, 현재 화면 젤 하단에 위치하면 현재 화면과 분리x(background 삭제)
⇒ keyboard 열면 없어짐
Toolbars and tab bars don’t appear together in the same view.
⇒ toolbar와 tab bar은 동시에 존재X
A toolbar provides a prominent and consistent location for frequently used commands
⇒ toolbar는 자주 사용되는 명령들을 일관된 위치(폰 화면 아래)에서 제공 가능
In a toolbar that contains three or fewer buttons, consider using concise text titles for additional clarity.
In a toolbar that has more than three buttons, consider using SF symbols to conserve space.
⇒ 버튼 적으면 text로, 많으면 symbol 사용
