You can look up Waze Community for reference.

Objective-C code snippet:

if ([[UIApplication sharedApplication]
canOpenURL:[NSURL URLWithString:@"waze://"]]) {

  // Waze is installed. Launch Waze and start navigation
  NSString *urlStr =
    [NSString stringWithFormat:@"waze://?ll=%f,%f&navigate=yes",
    latitude, longitude];

  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr]];

 } else {

  // Waze is not installed. Launch AppStore to install Waze app
  [[UIApplication sharedApplication] openURL:[NSURL
    URLWithString:@"http://itunes.apple.com/us/app/id323229106"]];
}

Swift code snippet:

if UIApplication.shared.canOpenURL(URL(string: "waze://")!) {
    // Waze is installed. Launch Waze and start navigation
    let urlStr = String(format: "waze://?ll=%f, %f&navigate=yes", latitude, longitude)
    UIApplication.shared.openURL(URL(string: urlStr)!)
} else {
    // Waze is not installed. Launch AppStore to install Waze app
    UIApplication.shared.openURL(URL(string: "http://itunes.apple.com/us/app/id323229106")!)
}
