SwiftUI pass param from views - swiftui

Question

I have this situation:
First View, in this view i got the current position and i save the latitude and longitude in two double type var: doublelat and doublelng
import SwiftUI
struct CoordinateView: View {
#ObservedObject var locationManager = LocationManager()
#State private var gotopage = false
var userLatitude: String {
let lat = String(format: "%.6f", locationManager.lastLocation?.coordinate.latitude ?? 0)
return "\(lat)"
}
var userLongitude: String {
let lng = String(format: "%.6f", locationManager.lastLocation?.coordinate.longitude ?? 0)
return "\(lng)"
}
var doubleLat : Double {
return locationManager.lastLocation?.coordinate.latitude ?? 0
}
var doubleLng : Double {
return locationManager.lastLocation?.coordinate.longitude ?? 0
}
private var getcoordinates: Bool {
if locationManager.statusCode == 0 {
return false
} else {
return true
}
}
var body: some View {
VStack {
HStack() {
Text("Your position")
.font(.headline)
Spacer()
}
VStack(alignment: .leading) {
HStack(){
Text("Lat")
Spacer()
Text("\(userLatitude)")
}.padding(5)
HStack(){
Text("Long")
Spacer()
Text("\(userLongitude)")
}.padding(5)
}
if getcoordinates {
HStack(alignment: .center){
Button("Go to next page") {
self.gotopage = true
}
}.padding()
VStack {
if self.gotopage {
AddressView(latitude: self.doubleLat, longitude: self.doubleLng)
}
}
}
}
.padding()
}
};
struct CoordinateView_Previews: PreviewProvider {
static var previews: some View {
CoordinateView()
}
}
Now just press on button Button("Go to next page"), go to view AddressView(latitude: self.doubleLat, longitude: self.doubleLng), with two param latitude and longitude.
This is AddressView:
import SwiftUI
struct AddressView: View {
var latitude: Double
var longitude: Double
#ObservedObject var apiManager = APIManager(lat: <latitude>, lng: <longitude>)
var body: some View {
.....
.....
}
struct AddressView_Previews: PreviewProvider {
static var previews: some View {
AddressView(latitude: 14.564378, longitude: 42.674532)
} }
In this second view i have to pass the two param (latitude and longitude) from previous view in this declaration:
#ObservedObject var apiManager = APIManager(lat: <latitude>, lng: <longitude>)
How can I do?

Answer 1

Try the following declaration for AddressView
struct AddressView: View {
var latitude: Double
var longitude: Double
#ObservedObject var apiManager: APIManager
init(latitude: Double, longitude: Double) {
self.latitude = latitude
self.longitude = longitude
self.apiManager = APIManager(lat: latitude, lng: longitude)
}
...
