Answer 1

I know this is an old question, but the following worked for me (I'm using xcode 8.3.3 and swift 3).

I added whatsapp query scheme inside Info.plist.

LSApplicationQueriesSchemes

    whatsapp

Info.plist

After adding it, the following works:

let urlString = "whatsapp://send?text=Message to share"

let urlStringEncoded = urlString.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)

let URL = NSURL(string: urlStringEncoded!)

if UIApplication.shared.canOpenURL(URL! as URL) {
    UIApplication.shared.openURL(URL! as URL)
}
