Swift tab bar view prepareforsegue

Question

In VC1 (collection view) this is my prepareforsegue code:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let segue = segue         


        

Answer 1

Have you checked whether the prepareForSegue in your TabBarController ever gets called?

It would never be called since the connection between a UITabBarController and its children view controllers isn't a storyboard segue. You should get a reference directly to the viewController from the UITabBarController by accessing its viewControllers collection at the index you want.

var tabBarController = segue.destination as UITabBarController
var destinationViewController = tabBarController.viewControllers[0] as YourViewController // or whatever tab index you're trying to access
destination.property = "some value"
