Using Swift I got the error that my \"TableViewController\" is unreachable because it has no entry points and no runtime access via [UIStoryboard instantiateViewControllerWithId
The problem is exactly as the warning says: this View Controller is unreachable because it has no entry points.
If you have only one View Controller then this controller is missing its entry point. You can fix this by setting this View Controller as "Is Initial View Controller".
If you have several View Controllers and this View Controller is not in the beginning of your storyboard sequence, then you are missing a segue which should display this View Controller. You can fix this by adding a segue which should show this View Controller.
In general, Xcode tells you that this View Controller is not connected to the storyboard sequence because it has no incoming connections.
