I've been searching for an answer to this question and found a few answers for doing something similar in Obj-C, adding the toolbar to the appdelegate and so forth, but I was wondering if there was a better to do this in Swift so that the toolbar displays across all the VCs. A Swift version of this, or this for example. I found this question but no one has offered any answers so does that mean there's no better way in Swift? I haven't used toolbars much and I'm not experienced enough with Swift to know when something simply is or is not possible. Thanks for any help.
UINavigationControllers feature an optional UIToolbar. Simply unhide it at the start of your first view controller (in viewDidLoad for example) to have it display throughout your app, ex:
navigationController.toolbarHidden = false
You can subsequently set your toolbar's items within each view controller by adding items to the view controller's toolbarItems property:
toolbarItems = itemsArray
