Create attributes text

[paoloandrea]

Hi, I created the "attributes" variable to allow users to insert other elements in the text field that opens full screen.

For example, if I assign attributes to the simple text field, I can add a title of a different font and color compared to the description. Just like in other tvOS apps.

import SwiftyAttributes
...
let title = title! .withAttributes ([
.font (.title1),
.textColor (.white)
])

let overview = text! .withAttributes ([
.font (.body),
.textColor (.white)
])
viewController.attributes = title + breakline + overview
