Push Notification Segment & smart text

I’m dealing with your recommendation of using the template.

My code is working but incomplete for my purpose of send to different user, should be easy but I don’t know how to write it.

On Swift this is the code:

and the template is this:

How to connect my swift code with the user.email ?

I found “add smart text” it’s possible to use it at Recipients? for replace “sq@sq.com”?
channelName = ‘default’ and user.email = ‘{Users.callEmail}’

Something is wrong because is working without smart text.

Maybe the solution is at templateValues but I don’t know how to write the code.

Thanks, Mario

Solved by “Target Individual Devices” not using Templates.

I found no solution to modified “RECIPIENTS”.
