There has been an error that sometimes repeats itself. How can I remove it? Struct Name: View { some data ... Struct ContentView: View { ... some data struct ContentView_Previews:        PreviewProvider {     static var previews: some View {         ContentView()     } } struct Name: View { // <- inwalid redeclaration of Struct Name    var body: some View {       Text("Name")    } } struct Name: View { // // <- inwalid redeclaration of Struct Name     var body: some View {        Text("Name")     } }

An error appears and I don't know how to solve it : Closure containing a declaration cannot be used with result builder 'ViewBuilder'. import SwiftUI Struct ContentView: View { var body: some View { // some code... struct ContentView_Previews: PreviewProvider { // <- error Closure containing a declaration cannot be used with result builder 'ViewBuilder'.     static var previews: some View {         ContentView()   } } Struct Name: View { // some code ... var body: some View { Text"some text" // some code ... Struct Name: View { var body: some View { Text"some text" Struct Name: View { var body: some View { Text"some text"

I can't fix this error. Cannot convert value of type '[Double]' to expected argument type 'Double' let someValue = Double(SomeValue / SomeValue) // error is here

How can I get rid of this error ? import SwiftUI @main struct Project_Health_calculatorsApp: App {     var body: some Scene {         WindowGroup {             ContentView() // <- error is here         }     } }
