Google maps destination SwiftUI - google-maps

Question

I am working on a project where users can add the addresses of their clients. I managed to make these addresses to be interactive so that when you tap on them a sheet shows the option to open either GoogleMaps or Apple Maps. However I am not sure how to set the specific address I tap to be the destination when the map opens. This is what I have:
.actionSheet(isPresented: $showingSheet){
let latitude = 51.49
let longitude = -30
let appleURL = "http://maps.apple.com/?daddr=\(latitude),\(longitude)"
let googleURL = "comgooglemaps://?daddr=\(latitude),\(longitude)&directionsmode=driving"
//let wazeURL = "waze://?ll=\(latitude),\(longitude)&navigate=false"
let googleItem = ("Google Map", URL(string:googleURL)!)
//let wazeItem = ("Waze", URL(string:wazeURL)!)
var installedNavigationApps = [("Apple Maps", URL(string:appleURL)!)]
if UIApplication.shared.canOpenURL(googleItem.1) {
installedNavigationApps.append(googleItem)
}
// if UIApplication.shared.canOpenURL(wazeItem.1) {
// installedNavigationApps.append(wazeItem)
// }
var buttons: [ActionSheet.Button] = []
for app in installedNavigationApps {
let button: ActionSheet.Button = .default(Text(app.0)) {
UIApplication.shared.open(app.1, options: [:], completionHandler: nil)
}
buttons.append(button)
}
let cancel: ActionSheet.Button = .cancel()
buttons.append(cancel)
return ActionSheet(title: Text("Navigate"), message: Text("Select an app..."), buttons: buttons)
Any suggestions?

Both Apple Maps and Google Maps have a similar URL scheme for opening their map for driving directions.
Apple Maps reference: https://developer.apple.com/library/archive/featuredarticles/iPhoneURLScheme_Reference/MapLinks/MapLinks.html
Google Maps URL scheme for iOS: https://developers.google.com/maps/documentation/urls/ios-urlscheme#directions
In both cases, the daddr value you're passing can be sent a full address, which the Maps product will then geocode and pinpoint.
You're currently sending a stringified version of your lat/lng coordinates in that string, which each maps product can use to derive a location. But there neither scheme seems to support an option of "here are the coordinates I want to use, and this is the address I want to show" – it's one or the other.
So if you take the address you have and enter it as a single string (don't forget to URL encode it – you may find it easiest to assemble your URL using the URLComponents and URLQueryItem helper objects) you ought to be able to use that encoded string as a new daddr value.
