I am having trouble with running my save button function. I am not sure why the function won't work.
I thought it was because i have too many arguments. I am just not sure what to do.
struct addALandmarkForm: View {
@Environment(\.presentationMode) var presentatoinMode
@EnvironmentObject var listViewModel: ListViewModel
@State var newLocationName: String = ""
@State var texts: String = "Enter a Description"
@State public var newPropertyType1 = false
@State public var propertyPrice: String = ""
@State var email: String = ""
@State var ownerName: String = ""
@State var alerTitle: String = ""
@State var showAlert: Bool = false
var body: some View {
NavigationView {
Form {
TextField("Location Name", text: $newLocationName)
Toggle("Property is Private ",
isOn: $newPropertyType1)
if newPropertyType1{
TextField("Asking/Starting Price", text: $propertyPrice)
.keyboardType(.numberPad)
}
TextEditor(text: $texts )
Section(header: Text("Owner")){
TextField("Enter an Email", text: $email)
TextField("Owner's First Name", text: $ownerName)
}
Section(header: Text("Submit")){
Button (action: saveButtonPressed, label:{
Label("Submit New Location", systemImage: "plus.square")
})
}
}
.navigationBarTitle("Add a New Location")
}
// this is where my issue is. Thi is the error that i get.
//Closure containing a declaration cannot be used with result builder 'ViewBuilder'
func saveButtonPressed() {
listViewModel.addItem(title: newLocationName, descrip: texts, price: propertyPrice, mail: email, owner: ownerName)
presentatoinMode.wrappedValue.dismiss()
}
}
}
struct addALandmarkForm_Previews: PreviewProvider {
static var previews: some View {
NavigationView{
addALandmarkForm()
}
.environmentObject(ListViewModel())
}
}
import SwiftUI
class ListViewModel: ObservableObject {
@Published var items: [ItemModel] = []
init(){
getItems()
}
func getItems() {
let newItems = [
ItemModel(newLocationName: "PFT", text: "Engineering building for LSU students. A great place to study and do business", newPropertyType1: true, propertyPrice: "1200", email: "test@email", ownerName: "Rob"),
ItemModel(newLocationName: "PFT", text: "Engineering building for LSU students. A great place to study and do business", newPropertyType1: true, propertyPrice: "1200", email: "test@email", ownerName: "Bob"),
ItemModel(newLocationName: "PFT", text: "Engineering building for LSU students. A great place to study and do business", newPropertyType1: true, propertyPrice: "1200", email: "test@email", ownerName: "Taylor")
]
items.append(contentsOf: newItems)
}
func addItem(title: String, descrip: String, price: String, mail: String, owner: String){
let newItem = ItemModel(newLocationName: title, text: descrip, newPropertyType1: false, propertyPrice: "1200", email: mail, ownerName: owner)
items.append(newItem)
}
}
The declaration of function saveButtonPressed() resides in the body of body.
You need to move it out of body.
struct AddALandmarkForm: View {
@Environment(\.presentationMode) var presentatoinMode
@EnvironmentObject var listViewModel: ListViewModel
@State var newLocationName: String = ""
@State var texts: String = "Enter a Description"
@State public var newPropertyType1 = false
@State public var propertyPrice: String = ""
@State var email: String = ""
@State var ownerName: String = ""
@State var alerTitle: String = ""
@State var showAlert: Bool = false
var body: some View {
NavigationView {
Form {
//...
} //<- End of `Form`
.navigationBarTitle("Add a New Location")
} //<- End of `NavigationView`
} //<- End of `body`
func saveButtonPressed() {
listViewModel.addItem(title: newLocationName, descrip: texts, price: propertyPrice, mail: email, owner: ownerName)
presentatoinMode.wrappedValue.dismiss()
}
}
By the way, in Swift, type names should start with Capital letters. You should not use addALandmarkForm as a struct name in Swift.
