Swift 4 - sharing location through UIActivityViewController - ios

Question

I'm trying to build an application where I can share an address and open that in any navigation app (Google maps, Apple maps, waze,...).
Below is the code that I currently have (after going through pages of google search results including dozens of stackoverflow questions)
#IBAction func navigeer(_ sender: Any) {
var items = [AnyObject]()
let latitude: Double = 52.033809
let longitude: Double = 6.882286
let locationTitle = "Navigate to this address"
let URLString = "https://maps.apple.com?ll=\(latitude),\(longitude)"
guard let cachesPathString = NSSearchPathForDirectoriesInDomains(.cachesDirectory, .userDomainMask, true).first else {
print("Error: couldn't find the caches directory.")
return
}
if let url = NSURL(string: URLString) {
items.append(url)
}
let vCardString = [
"BEGIN:VCARD",
"VERSION:3.0",
"N:;Shared Location;;;",
"FN:Shared Location",
"item1.URL;type=pref:http://maps.apple.com/?ll=\(latitude),\(longitude)",
"item1.X-ABLabel:map url",
"END:VCARD"
].joined(separator: "\n")
let vCardFilePath = (cachesPathString as NSString).appendingPathComponent("vCard.loc.vcf")
let nsVCardData = NSURL(fileURLWithPath: vCardFilePath)
let shareItems:Array = [nsVCardData]
let activityController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
present(activityController, animated:true, completion: nil)
}
When I run the application on my simulator I get the following:
After clicking the share button
Why don't I get app suggestions like Apple maps or Google maps? I also don't get why it suggests me to copy it to contacts..
Thanks in advance.

To share location using UIActivityViewController, Swift 5
func activityItems(latitude: Double, longitude: Double) -> [AnyObject]? {
var items = [AnyObject]()
let URLString = "https://maps.apple.com?ll=\(latitude),\(longitude)"
if let url = NSURL(string: URLString) {
items.append(url)
}
let locationVCardString = [
"BEGIN:VCARD",
"VERSION:3.0",
"PRODID:-//Joseph Duffy//Blog Post Example//EN",
"N:;Shared Location;;;",
"FN:Shared Location",
"item1.URL;type=pref:\(URLString)",
"item1.X-ABLabel:map url",
"END:VCARD"
].joined(separator: "\n")
guard let vCardData : NSSecureCoding = locationVCardString.data(using: .utf8) as NSSecureCoding? else {
return nil
}
let vCardActivity = NSItemProvider(item: vCardData, typeIdentifier: kUTTypeVCard as String)
items.append(vCardActivity)
return items
}
How to use?
if let shareObject = self.activityItems(latitude: 52.033809, longitude: 6.882286) {
//open UIActivityViewController
}

Try this..
// if the device has google maps installed in it
if (UIApplication.shared.canOpenURL(NSURL(string:"comgooglemaps://")! as URL)) {
UIApplication.shared.openURL(NSURL(string:
"comgooglemaps://?saddr=&daddr=\(myLatitude),\(myLongitude)&directionsmode=driving")! as URL)
}
// if google maps is not installed, try apple map
else if (UIApplication.shared.canOpenURL(NSURL(string:"http://maps.apple.com/maps")! as URL)) {
// apple map
let url = "http://maps.apple.com/maps?saddr=\(from.latitude),\(from.longitude)&daddr=\(to.latitude),\(to.longitude)"
UIApplication.shared.openURL(URL(string:url)!)
}
// if apple map is also not there, it will show an appStore link to download apple map application.
