Reply to Back button removed in the navigation bar once the view loads
I had a view that used to be opened from a list. The view contained a scrollview and all the items are listed in it including the TextFields, Texts, Button, Picker and others. I was using a custom modifier in the toolbar trialing items to show a notification Sheet and a logout button. Below is the custom code: ScrollView{ // some code }.toolbar(){       ToolbarItem(placement: .navigationBarTrailing){         Logout().environmentObject(settings)       }     } The logout class held the messaging sheet and the logout button. This caused the back button to be disappearing whenever the view loaded. I have now changed it to: ScrollView{ //some code } .navigationBarItems(trailing: Logout().environmentObject(settings))

Reply to Unable to create list of string from json response
In the end i used a ForEach loop for this. I actually wished to create a list of textfields which could be add on the basis of the remarks received from the API call. Also this list needed to be dynamic, i.e, I could add or remove the textfields dynamically by using buttons which is why I wanted to add a list... Unfortunately I couldn't. But now I created a a for loop and then added two buttons which could add or remove the textfields and it now works perfectly. Here is the code for this. } if showUpdateButton { HStack{ Button(action:{ self.remarksList.append("") }) { Text("Add Remarks") } Spacer() Button(action:{ _ = self.remarksList.popLast() }) { Text("Delete Remarks") } }.padding(30) }

@OOPer the "currentFrResponse" is an object of struct pasted below: struct CurrentFrResponse: Codable {     var frId : String?     var clientFrId : String?     var customerRefId : String?     var requestorName : String?     var requestorContactNo : String?     var location : Location?     var building : Building?     var division : Division?     var locationDesc : String?     var faultCategory : Division?     var priority : Division?     var department : Division?     var maintGrp : Division?     var remarks : [String]?     var purchaseOrder : String?     var attendedBy : [AttendedBy]? } I have removed some properties from this struct to make it simple.
