Swift Question
Why doesn't my alert view controller work
let alert = UIAlertController(title: "Title", message: "message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel, handler: nil))
alert.addAction(UIAlertAction(title: "Title", style: UIAlertActionStyle.default, handler: { action in self.alertFunc() }))
If I build this the alert view doesn't appear. What have I missed?
P.S. I know there are some similar question but to find out what they have and I have missed is hard

You need to present it too on your current context:
self.present(alert, animated: true, completion: nil)
Add that row at the end of your alert declaration:
let alert = UIAlertController(title: "Title", message: "message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel, handler: nil))
alert.addAction(UIAlertAction(title: "Title", style: UIAlertActionStyle.default, handler: { action in
self.alertFunc()
}))
self.present(alert, animated: true, completion: nil)
