Different Build Schemes -> Error: -Onone Swift optimization level to use previews

I have a sample SwiftUI iOS app. As shown in the screenshot below, my project has three configurations: Debug, MyDebug, Release.

If I select the Debug or MyDebug scheme, I get a preview. But if I select the Release scheme, I get an error that says the following.

”***.app” needs -Onone Swift optimization level to use previews (current setting is -O)

, where *** is the app name.

It probably has nothing to do with the Preview error, but the Info.plist has a dictionary such that the key name is devMode, and the value is $(DEVMODE). And I have a user-defined setting as shown below.

My ContentView has the following.

import SwiftUI
 
struct ContentView: View {
    @State private var state: String = ""
    
    var body: some View {
        VStack {
            Text("Hello, world!: \(state)")
        }
        .onAppear {
            if let devMode = Bundle.main.object(forInfoDictionaryKey: "devMode") as? String {
                print("Development mode: \(devMode)")
                state = devMode
            }
            if let path = Bundle.main.path(forResource: "Info", ofType: "plist") {
                if let dict = NSDictionary(contentsOfFile: path) {
                    print("**** \(dict)")
                }
            }
            #if DEBUG
                print("Debug")
            #elseif MYDEBUG
                print("MyDebug")
            #else
                print("Que?")
            #endif
        }
    }
}
 
#Preview {
    ContentView()
}

So my question is how I get the preview for all three build schemes? Muchos thankos.
