prepare(for:sender:) not getting called

Question

I downloaded Apple's MyLife sample project and attempted to build and run it using Xcode 8 beta 6.

There are two places where a view controller has implemented the prepare(for:sender:) call to do stuff before a storyboard segue is performed.

    override func prepare(for segue: UIStoryboardSegue, sender: AnyObject?) {

That line has an error saying "Method does not override any method from its superclass".

If I remove the override, the app builds but the method isn't called when it should be.

Did you try "Edit -> Convert -> To Latest Swift Syntax ..." ? — Martin R, Aug 15 '16 at 20:55
It's already a Swift 3 project, just not the very *latest* version of Swift 3. — Frank Schmitt, Aug 15 '16 at 20:56

The method signature has changed. sender is now Any? instead of AnyObject?

override func prepare(for segue: UIStoryboardSegue, sender: Any?)

This is to coincide with the changes to how Swift is bridged with obj-c, described here under "New in Xcode 8 beta 6 - Swift Compiler"

Just discovered that myself. Also for whatever reason it's not showing up in autocomplete. – Frank Schmitt Aug 15 '16 at 20:54
