Answer 1

add a new scheme for your App

enter image description here

as Shown above image...

then, write a code below on IBAction of your Today Extension

@IBAction func btnFirstWidgetAction() {
    let url: URL? = URL(string: "schemename://secondViewController")!
    if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}

@IBAction func btnSecondWidgetAction() {
    let url: URL? = URL(string: "schemename://secondViewController")!
    if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}

@IBAction func btnThirdWidgetAction() {
    let url: URL? = URL(string: "schemename://thirdViewController")!
    if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}

than, add method application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) in AppDelegate file and write code to redirect in specific ViewController in this method.

//call when tap on Extension and get url that is set into a ToadyExtension swift file...
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
    let urlPath : String = url.absoluteString
    print(urlPath)

    if self.isContainString(urlPath, subString: "firstViewController") {
        //here go to firstViewController view controller
    }
    else if self.isContainString(urlPath, subString: "firstViewController") {
        //here go to secondViewController view controller
    }
    else {
        //here go to thirdViewController view controller
    }

    return true
} 

this method used for check your string is contains as sub string that are given in widget button action. if contain than true otherwise false

 func isContainString(_ string: String, subString: String) -> Bool {
    if (string as NSString).range(of: subString).location != NSNotFound { return true }
    else { return false }
}
