How to draw a gradient border button?

My Problem

Last week, my partner showed me his design for our application. Everything is great, easily implemented with some custom controls. But wait, something is not in my knowledge.

A button with gradient border. Never try it before. Up to now, I just created gradient background views 2 times in previous projects. Googled and found some good results.

Android Studio Shortcuts (Mac)

Notes:

• Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
• Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
• A fairly complete shortcut list can be found here.

Useful symbols:

public extension UITableView {

  public func beginRefreshing() {
    // Make sure that a refresh control to be shown was actually set on the view
    // controller and the it is not already animating. Otherwise there's nothing
    // to refresh.
    guard let refreshControl = refreshControl, !refreshControl.isRefreshing else {
      return
