[SOLVED] Open an Alert asking to choose App to open map with


I have a view controller with map kit integrated. I need to shoot an alert before opening that map, asking to choose from all similar applications of maps to open it with. For instance, if google maps app is installed in my iPhone, there should be an option for it, along with the default mapkit view. Is there a possibility to achieve this functionality which scans every similar app from iphone and returns the result as options to open map with.


Swift 5+ solution based on previous answers, this one shows a selector between Apple Maps, Google Maps, Waze and City Mapper. It also allows for some optional location title (for those apps that support it) and presents the alert only if there are more than 1 option (it opens automatically if only 1, or does nothing if none).

func openMaps(latitude: Double, longitude: Double, title: String?) {
    let application = UIApplication.shared
    let coordinate = "\(latitude),\(longitude)"
    let encodedTitle = title?.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) ?? ""
    let handlers = [
        ("Apple Maps", "http://maps.apple.com/?q=\(encodedTitle)&ll=\(coordinate)"),
        ("Google Maps", "comgooglemaps://?q=\(coordinate)"),
        ("Waze", "waze://?ll=\(coordinate)"),
        ("Citymapper", "citymapper://directions?endcoord=\(coordinate)&endname=\(encodedTitle)")
        .compactMap { (name, address) in URL(string: address).map { (name, $0) } }
        .filter { (_, url) in application.canOpenURL(url) }

    guard handlers.count > 1 else {
        if let (_, url) = handlers.first {
            application.open(url, options: [:])
    let alert = UIAlertController(title: R.string.localizable.select_map_app(), message: nil, preferredStyle: .actionSheet)
    handlers.forEach { (name, url) in
        alert.addAction(UIAlertAction(title: name, style: .default) { _ in
            application.open(url, options: [:])
    alert.addAction(UIAlertAction(title: R.string.localizable.cancel(), style: .cancel, handler: nil))
    contextProvider.currentViewController.present(alert, animated: true, completion: nil)

Note this solution uses R.swift for string localization but you can replace those with NSLocalizedString normally, and it uses a contextProvider.currentViewController to get the presented UIViewController, but you can replace it with self if you are calling this in a view controller already.

As usual, you need to also add the following to your app Info.plist:
