Unchecking the checkbox, removes the arrow. In the View Controller section, the Is Initial View Controller is selected. With the view controller selected, open the Attributes Inspector on the right. The arrow indicates that view controller is the initial view controller of the storyboard.

Notice that an arrow is pointing to the view controller in the storyboard. Open Main.storyboard and select the View Controller Scene. Setting the Initial View Controller of the Storyboard Let's take a look at each of these issues in detail. We cannot instantiate it programmatically because the my view controller doesn't have a storyboard ID or storyboard identifier. The My View Controller Scene has no entry points because (1) the my view controller is not the initial view controller of the storyboard and (2) it isn't reachable via a segue. If none of these requirements are met, the view controller is unreachable. is the initial view controller of the storyboard.What you need to understand before we continue is that a storyboard can only instantiate a view controller if the view controller:

That should teach you how to use storyboards without becoming frustrated. The goal of this episode of Swift Help is to dissect this warning and understand what it means. The warning reads My View Controller is unreachable because it has no entry points, and no identifier for runtime access view. If we build the project, Xcode warns us that one of the view controllers in Main.storyboard is unreachable. Main.storyboard contains two scenes, View Controller Scene and My View Controller Scene. The project defines two UIViewController subclasses, ViewController and MyViewController. We are only interested in Main.storyboard. The project has two storyboards, Main.storyboard and LaunchScreen.storyboard.

You can download the project if you want to follow along with me. I have created a starter project to get us started. In this episode of Swift Help, I show you how to avoid unreachable view controllers when working with storyboards. The execution is where I am lacking, because I am not sure how to transfer this array to the MapView.Storyboards are great for building user interfaces, but it can sometimes be frustrating to debug the cryptic warnings and errors Xcode throws at you. My initial idea is to have a specific array of coordinates, and any new coordinates will be appended to this array.

My FirstVC consists of a button "Add Locations" that segues to OtherVC which the user can input the coordinates. I am trying to construct a Map App that can receive user inputs of latitude and longitude coordinates that when entered, will place a pin on a map in a different tab.
