Hello @OOPer, Thank for your quick reply. It doesn't fix my issue yet : typeStreetNumber: Binding<String>(transaction: SwiftUI.Transaction(plist: []), location: SwiftUI.LocationBox<SwiftUI.ObservableObjectLocation<Healthsafe.NewPatient, Swift.String>>, _value: "") typeStreet: Binding<String>(transaction: SwiftUI.Transaction(plist: []), location: SwiftUI.LocationBox<SwiftUI.ObservableObjectLocation<Healthsafe.NewPatient, Swift.String>>, _value: "") The thing is I need it to submit my JSON request. Here is what is needed: { &#9;"lastName": "Appleseed", &#9;"firstName": "John", &#9;"age": 20, &#9;"phoneNumber": [ &#9;&#9;"+33658893939", &#9;&#9;"0638495959", &#9;&#9;"0139384458" &#9;], &#9;"address": { &#9;&#9;"streetNumber": 3, &#9;&#9;"typeStreetNumber": [ &#9;&#9;&#9;"", &#9;&#9;&#9;"bis", &#9;&#9;&#9;"ter", &#9;&#9;&#9;"quater" &#9;&#9;], &#9;&#9;"typeStreet": [ &#9;&#9;&#9;"rue", &#9;&#9;&#9;"avenue", &#9;&#9;&#9;"boulevard", &#9;&#9;&#9;"chemin" &#9;&#9;], &#9;&#9;"street": "des paradis", &#9;&#9;"zipCode": 95170, &#9;&#9;"city": "Paris", &#9;&#9;"country": "France" &#9;}, &#9;"email": "test@gmail.com", &#9;"password": "oldboy", &#9;"confirmationPassword": "oldboy" } Unless for the typeStreet I can do a switch case where I assign the selected value directly to NewPatient.typeStreet 🤔 Thank you, P.

In this function : func submit() {         guard let encoded = try?

HTTPURLResponse,                     (200...299).contains(httpResponse.statusCode) else {                     self.handleServerError(res)                 return             }             if let data = data {                 let decoder = JSONDecoder()                 if let json = try? decoder.decode(NewPatient.self, from: data) {                     print(json)                 }                 else {                     let dataString = String(decoding: data, as: UTF8.self)                     print("Invalid response \(dataString)")                 }             }         }.resume()     }

file - https://developer.apple.com/forums/content/attachment/123e8034-0ad1-474a-8702-7ded04790b5d I'd like to share the entire file, but it is to log for here ... This is why I liked my GitHub, where the project is. With all the code block, you have the overall file. You have the important elements of the class NewPatient, and the view SignUpClientView. SignUpClient is just a view controller depending on what the user click.

my bad sorry. here you will have the APIRequests.swift file where are the class declaration. https://github.com/Paul-Rouillard/iOS-Healthsafe/tree/master/Healthsafe/src under src/view/SignUpClient.swift is the source code above.

Good evening, The value for typeStreetNumber and typeStreet in the JSON are arrays, and each array seems containing all possible values. Do you really need to send such all possible values to the API? The arrays are the possibilities the user can sent to the API. In this case, the API waits for ether one of the possibilities. "phoneNumber": [ "+33658893939", "0638495959", "0139384458" ] I just need to send the user selection in the JSON.

Sorry but it doesn't work. Do tou think I can use this : Picker("Number ext.", selection: $patient.indexStreetNbr) { ForEach (0 ..< NewPatient.typeStreetNbr.count) { Text(NewPatient.typeStreetNbr[$0]) } } .pickerStyle(SegmentedPickerStyle()) .onReceive([NewPatient.typeStreetNbr].publisher.first, perform: { _ in self.patient.checkAddr() }) And call a function I create in the class like so : func checkAddr() { switch indexStreet { case 0: self.typeStreet = "rue"     case 1: self.typeStreet = "boulevard"    case 2: self.typeStreet = "avenue"    case 3: self.typeStreet = "chemin" default: self.typeStreet = "rue" } }

Sorry, but it is completely unclear. Sorry for being so unclear. What is it which doesn't work? What do you mean by doesn't work? It does not compile? It compiles but causes runtime errors? It compiles and runs without errors but shows unexpected results? I just don't understand how to do it. Is it possible exchange about this subject elsewhere ? more easily to explain one another what it's going wrong ?

Using publisher for an Array literal does not work as expected in almost all cases This is what I don't understand. How am I supposed to do it ? Also, the difference between this two way : @StateObject var newPatient = NewPatient() @ObservedObject var newPatient: NewPatient I'm exhausted of trying about this issue I'm facing for some time now. If you wouldn't mind explain it a bit easier, I'd be grateful. Thanks a lot again

I find the solution ! 😇 I will honest, it is quit dirty but it is working ! Picker("Street desc.", selection: $patient.indexStreet) { ForEach (0 ..< NewPatient.typeStrt.count) { Text(NewPatient.typeStrt[$0]) } } .pickerStyle(SegmentedPickerStyle()) .onAppear(perform: { self.patient.typeStreet = NewPatient.typeStrt[self.patient.indexStreet] }) Regards and thank you for your help.

Thank you for your different version and explication. I will use the following : var data = "Key0:Value\nKey1:Value\nKey2:Value\nKey3:Value\n" var deciphered = data.split(separator: "\n").reduce(into: [String: String]()) { &#9;&#9;&#9;&#9;&#9;&#9;let str = $1.split(separator: ":") &#9;&#9;&#9;&#9;&#9;&#9;if let first = str.first, let value = str.last { &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;$0[String(first)] = String(value) &#9;&#9;&#9;&#9;&#9;&#9;} &#9;&#9;&#9;&#9;} The little issue I'm facing now, is to display the dictionary. I'm using SwiftUI for my app UI. Here is the code: struct NFCMobileView: View { &#9;&#9;@Binding var data: String &#9;&#9;var body: some View { &#9;&#9;&#9;&#9;var deciphered = data.split(separator: "\n").reduce(into: [String: String]()) { &#9;&#9;&#9;&#9;&#9;&#9;let str = $1.split(separator: ":") &#9;&#9;&#9;&#9;&#9;&#9;if let first = str.first, let value = str.last { &#9;&#9;&#9;&#9;&#9;&#9;&#9;&#9;$0[String(first)] = String(value) &#9;&#9;&#9;&#9;&#9;&#9;} &#9;&#9;&#9;&#9;} &#9;&#9;&#9;&#9;HStack { &#9;&#9;&#9;&#9;&#9;&#9;Text("Last Name") &#9;&#9;&#9;&#9;&#9;&#9;TextField("", text: deciphered["lastName"]) // error &#9;&#9;&#9;&#9;} &#9;&#9;} } Cannot convert value of type 'String?' to expected argument type 'Binding<String>' This is the error I'm having I'm getting the binding value data from what is on the NDEF tag

Sorry I opened this new request, with the edits you suggested : https://developer.apple.com/forums/thread/670309

If I would need to access different value from my dictionary (like the code snippet here-under), will I need to return n times my HStack or my Form ? struct NFCMobileView: View {     @Binding var data: String     @State var decipheredString: String     var body: some View {         var deciphered = data.split(separator: "\n").reduce(into: [String: String]()) {             let str = $1.split(separator: ":")             if let first = str.first, let value = str.last {                 $0[String(first)] = String(value)             }         }         Form {             Group {                 HStack {                     Text("Last name")                     TextField("", text: deciphered["lastName"] ?? "")                 }                 HStack {                     Text("First name")                     TextField("", text: deciphered["firstName"] ?? "")                 }                 HStack {                     Text("Gender")                     TextField("", text: deciphered["gender"] ?? "")                 }                 HStack {                     Text("Age")                     TextField("", text: deciphered["Key3"] ?? "")                 } &#9;&#9;&#9;&#9;&#9;&#9;}         } &#9;&#9;} }

Happy New year ! Thank you for your help !

I'm having an issue updating the dictionary now ... 😬 Do you have any idea ? The goal now is to reformat the data from the dictionary into string. I'm doing it like so : Button(action: {                 self.allowModifications = true                 print("\(String(describing: self.deciphered["lastName"])")) /* this line prints -> Optional("Paul") */             }) {                 Text("Edit")             } nfcWriteButton(data: $data)                 .onTapGesture {                     self.data = "lastName:\(self.deciphered["lastName"])\ngender:\(self.deciphered["gender"])\nfirstName:\(self.deciphered["firstName"])\nage:\(self.deciphered["age"])\n"                 } I also tried to silence the warning with String(describing: as Xcode suggested it but it does not change...
