swift - How to open app from email URL in iOS 9? -

i've tried like:

in appdelegate:

func application(application: uiapplication, handleopenurl url: nsurl) -> bool {     var returnvalue = false     let urlstring = url.absolutestring     print(urlstring)     if(urlstring.hasprefix("")){         returnvalue = true     }     return returnvalue } 

in info.plist

<key>cfbundleurltypes</key> <array>     <dict>         <key>cfbundleurlname</key>         <string>co.example.exampleapp</string>         <key>cfbundleurlschemes</key>         <array>             <string>example</string>         </array>     </dict> </array> 

but doesn't work. want app opens link send via email, has idea make work?

for future users, @isashok mentioned in comments, handleopenurl function is deprecated of ios 9.

for newer versions of ios need use following function (apple docs):

optional func application(_ app: uiapplication,                   open url: url,                options: [uiapplicationopenurloptionskey : any] = [:]) -> bool 

you'll able keep body of function same before, , work.
