I just started to learn Swift programing language and have a question. I'm trying to create a simple one-page application where you can add movies to a favorite list. Movies must have 2 properties: title (string, mandatory) and year (integer, mandatory). But I have a problem, I don't know how to put it in one row. And also, how to ignore duplicate movies?
import SwiftUI
struct Movie: Identifiable {
let id = UUID()
var title: String
}
class Model: ObservableObject {
@Published var movies: [Movie] = []
}
struct DynamicList: View {
@StateObject var model = Model()
@State var text = ""
@State var year = ""
var body: some View {
VStack {
Section() {
TextField("Title", text: $text)
.padding()
.border(.gray)
TextField("Year", text: $year)
.padding()
.border(.gray)
.keyboardType(.numberPad)
Button(action: {
self.addToList()
}, label: {
Text("Add")
.frame(width: 80, height: 40, alignment: .center)
.background(Color.blue)
.cornerRadius(8)
.foregroundColor(.white)
})
.padding()
}
List {
ForEach(model.movies) { movie in
MovieRow(title: movie.title)
}
}
}
.padding()
}
func addToList() {
guard !text.trimmingCharacters(in: .whitespaces).isEmpty else {
return
}
guard !year.trimmingCharacters(in: .whitespaces).isEmpty else {
return
}
let newMovie = Movie(title: text)
model.movies.append(newMovie)
text = ""
let newYear = Movie(title: year)
model.movies.append(newYear)
year = ""
}
}
struct MovieRow: View {
let title: String
var body: some View {
Label (
title: { Text(title)},
icon: { Image(systemName: "film") }
)
}
}
struct DynamicList_Previews: PreviewProvider {
static var previews: some View {
DynamicList()
}
}

Maybe someone will need a similar solution, here is my result:
import SwiftUI
struct Movie: Identifiable {
let id = UUID()
var title: String
var year: String
}
class Model: ObservableObject {
@Published var movies: [Movie] = []
}
struct DynamicList: View {
@StateObject var model = Model()
@State var text = ""
@State var year = ""
var body: some View {
VStack {
Section() {
TextField("Title", text: $text)
.padding()
.border(.gray)
TextField("Year", text: $year)
.padding()
.border(.gray)
.keyboardType(.numberPad)
Button(action: {
self.addToList()
}, label: {
Text("Add")
.frame(width: 80, height: 40, alignment: .center)
.background(Color.blue)
.cornerRadius(8)
.foregroundColor(.white)
})
.padding()
}
List {
ForEach(model.movies) { movie in
MovieRow(title: movie.title, year: movie.year)
}
}
}
.padding()
}
func addToList() {
guard !text.trimmingCharacters(in: .whitespaces).isEmpty else {
return
}
guard !year.trimmingCharacters(in: .whitespaces).isEmpty else {
return
}
let newMovie = Movie(title: text, year: year)
model.movies.append(newMovie)
text = ""
year = ""
}
}
struct MovieRow: View {
let title: String
let year: String
var body: some View {
Label (
title: { Text(title " " year)},
icon: { Image(systemName: "film") }
)
}
}
struct DynamicList_Previews: PreviewProvider {
static var previews: some View {
DynamicList()
}
}

Try this way hope fix this issue. before appending
guard let yearValue = Int(year) , yearValue.count > 0 else { return }
