ios - Swift: How to open a new app when UIButton is tapped

Question

I have an app and when a uibutton is clicked, I want to open another app that is already installed (i.e. Waze). How can I do such? Big thanks.

Try this. For example you want to open an Instagram app:

let instagramHooks = "instagram://user?username=johndoe"
let instagramUrl = URL(string: instagramHooks)!
if UIApplication.shared.canOpenURL(instagramUrl)
{  
    UIApplication.shared.open(instagramUrl)
} else {
    //redirect to safari because the user doesn't have Instagram
    UIApplication.shared.open(URL(string: "http://instagram.com/")!)
}
