How to use Picker with data model

Question

I am trying to make a year selector, with information that comes from an array, but whenever I select an option the selector always returns automatically to the first position, how could I save the selected year in my $ i.anio?

Thank you

//---------------MODEL----------------- struct SysNoAntpatologicosModel { var anio: Int var descripcion: String var idantnopat: Int var nombre: String var presente: Bool } //-------------ARRAY---------------- [{ anio = 2001; descripcion = "test1"; idantnopat = 38; nombre = Accidente; presente = 0; }, { anio = 2002; descripcion = "test2"; idantnopat = 42; nombre = Inmunizacion; presente = 0; } ] @State var dataSys : [SysNoAntpatologicosModel] = [] ForEach($dataSys, id: \.idantnopat) { $i in HStack{ Picker("", selection: $i.anio) { ForEach(2000...2021, id: \.self) { Text($0) } } .pickerStyle(InlinePickerStyle()) .onChange(of: i.anio) { tag in print("year: \(tag)") } } }

What is the outer ForEach, do you have a list of pickers in your view? — Joakim Danielson

You are mixing types wildly here, the picker contains Int values but for the data you presented anio is a String but in the struct anio is a Date. Very confusing. — Joakim Danielson

@JoakimDanielson I'll change the data types to integer, I'll try again — Laura Ramírez

@JoakimDanielson It worked for me changing all the type of data to integer, thanks! — Laura Ramírez

With your edits, you're very close -- you just need to add "" around the Text input so that it will compile:

struct SysNoAntpatologicosModel { var anio: Int var descripcion: String var idantnopat: Int var nombre: String var presente: Bool } struct ContentView : View { @State var dataSys : [SysNoAntpatologicosModel] = [.init(anio: 2001, descripcion: "test1", idantnopat: 38, nombre: "Accidente", presente: false), .init(anio: 2002, descripcion: "test2", idantnopat: 42, nombre: "Inmunizacion", presente: false), ] var body: some View { ForEach($dataSys, id: \.idantnopat) { $i in HStack{ Picker("", selection: $i.anio) { ForEach(2000...2021, id: \.self) { Text("\($0)") //<-- Here } } .pickerStyle(InlinePickerStyle()) .onChange(of: i.anio) { tag in print("year: \(tag)") } } } } }

It worked for me changing all the type of data to integer, thanks!
