Open My application from my keyboard extension in swift 3.0

Question

I am trying to open from my keyboard extension. I am having custom keyboard and I have add that keyboard from setting. On my custom keyboard there is one button “Show More”, and I want to open my app on this button click. So I have tried following code : ``` let context = NSExtensionContext() context.open(url! as URL, completionHandler: nil) var responder = self as UIResponder? while (responder != nil) { if responder?.responds(to: Selector("openURL:")) == true { responder?.perform(Selector("openURL:"), with: url) } responder = responder!.next } ``` It is working successfully, but as we know in swift `Selector("method_name:")` is deprecated and use `#selector(classname.methodname(_:))` instead so it is giving warning. And I want to solve that warning. So I have tried as Xcode automatically suggested : ``` if responder?.responds(to: #selector(UIApplication.openURL(_:))) == true { responder?.perform(#selector(UIApplication.openURL(_:)), with: url) } ``` Also tried : ``` if responder?.res…

Swift 5.0:

Open Info.plist of hosting app.

- Add Url Types -> Item 0 -> Url Schemes -> Item 0 : "yourappname"

- Add Url Types -> Item 0 -> Url Schemes -> URL Identifier: "your bundle id"

Go to Keyboard App:

Add following code properly:

```
@objc func openURL(_ url: URL) {
       return
    }

func openApp(_ urlstring:String) {

var responder: UIResponder? = self as UIResponder
       let selector = #selector(openURL(_:))
       while responder != nil {
          if responder!.responds(to: selector) && responder != self {
             responder!.perform(selector, with: URL(string: urlstring)!)
             return
          }
          responder = responder?.next
        }
     }
```

Call : openApp ("yourappname://your bundle id")
