Concept

popover is used in SwiftUI to present content in a small overlay attached to a view.

It allows apps to:

show temporary floating content
present extra information
display anchored UI above the current screen

Core flow:

Button / State Change → Popover Appears → Dismiss

What It Does

A popover displays content above the current view without replacing it.

It is commonly used for:

extra details
small action panels
contextual content
temporary information

A popover is usually attached to the view that triggered it.

Basic Structure

.popover(isPresented: $showPopover) {
    PopoverContentView()
}

Here:

isPresented → controls whether the popover appears
PopoverContentView() → content shown inside the popover

Using State With Popover

A popover is usually controlled with @State.
