Preview throwing error in SwiftUI: ConfigurationError: noPreviewInfos

I am using Xcode 12.4 in macOS Catalina 10.15.7 version. While preview SwiftUI code:

import SwiftUI
struct SwiftUINewView: View {
    var body: some View {
        Text("Ayush Gupta")
    }
}

struct SwiftUINewView_Previews: PreviewProvider {
    static var previews: some View {
        SwiftUINewView()
    }
}

I am getting error:

ConfigurationError: noPreviewInfos(arch: "x86_64", sdkRoot: "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.4.sdk")

Is there any solution for this issue? Actually I am trying to integrate SwiftUI in old/existing UIKit project which is now supporting iOS 13.0 SDK.
