MultiSheet

By default, SwiftUI views with multiple .sheet calls in the same body will only use the last one in the chain of modifiers and ignore all previous ones.

struct NoMultiSheetDemoView: View {
    @State var sheetAPresented = false
    @State var sheetBPresented = false
    @State var sheetCPresented = false

    var body: some View {
        VStack(spacing: 20) {
            Button("Sheet A") { sheetAPresented = true }
            Button("Sheet B") { sheetBPresented = true }
            Button("Sheet C") { sheetCPresented = true }
        }
        .sheet(isPresented: $sheetAPresented) { Text("Sheet A") } // does not work
        .sheet(isPresented: $sheetBPresented) { Text("Sheet B") } // does not work
        .sheet(isPresented: $sheetCPresented) { Text("Sheet C") } // works
    }
}

MultiSheet brings a .multiSheet modifier to declare multiple sheet modifiers in the same view body.

struct MultiSheetDemoView: View {
    @State var sheetAPresented = false
    @State var sheetBPresented = false
    @State var sheetCPresented = false

    var body: some View {
        VStack(spacing: 20) {
            Button("Sheet A") { sheetAPresented = true }
            Button("Sheet B") { sheetBPresented = true }
            Button("Sheet C") { sheetCPresented = true }
        }
        .multiSheet {
            $0.sheet(isPresented: $sheetAPresented) { Text("Sheet A") } // works
            $0.sheet(isPresented: $sheetBPresented) { Text("Sheet B") } // works
            $0.sheet(isPresented: $sheetCPresented) { Text("Sheet C") } // works
        }
    }
}

Note:

MultiSheet does not enable "nested" sheets; it just enables multiple sheets appearing within a view body one at a time. For this reason, it's recommended that your sheets' presentation be dependant on a source of truth that ensures only one of them is presented at any given time.

Hopefully Apple will introduce support for multiple sheets in a future iteration of SwiftUI, rendering this library unnecessary.
