SwiftUI - What is the difference between sheet and actionSheet?

SwiftUI has these two modifiers:

.actionSheet(isPresented: $showActionPurchase) { () -> ActionSheet in

and

.sheet(isPresented: $showAlert,

one presents an action sheet and the other presents a sheet (?)

Why? What is the difference between these elements, if any?

sheet used for showing some view modal-way, but actionSheet is kind of alert view! they are very diffrent topic!

    import SwiftUI

struct ContentView: View {
    
    @State var showSheet = false
    @State var showActionSheet = false
    
    let appActionSheet = ActionSheet(title: Text("ActionSheet"), message: Text("I am an ActionSheet"), buttons: [
        .default(Text("some text")),
        .cancel()
    ])
    
    
    var body: some View {

        VStack
        {
            
            Button("show sheet") {showSheet.toggle()}.padding()
            
            Button("show actionSheet") {showActionSheet.toggle()}.padding()
            
            
        }.font(Font.title.bold())
        .sheet(isPresented: $showSheet, content: {sheetView()})
        .actionSheet(isPresented: $showActionSheet, content: {appActionSheet})

    }
}



struct sheetView: View {
    var body: some View {
        
        ZStack
        {
            Color.red
            Text("I am sheet view")
        }.ignoresSafeArea()
    }
}
