Is it possible to launch one application on click from another?

Question

iOS

Conditionally, the application offers to check mail. It is necessary to launch the second application (mail) by clicking in the first application. And one more thing ... Is it possible to display a list of applications installed on the iphone in the application in order to select, for example, the same mail client, to work with it by default in the first application. Hope I didn't confuse too much. :)

Answer 1

You can open other applications by url scheme. It looks like this

guard let url = URL(string: "mail://") else { return }
if UIApplication.shared.canOpenURL(url) {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

But you can’t get a list of applications, but you can try to make a request for each url scheme from popular applications using the method
if the url can be opened, then add it to your list of applications.
