Creating an object

 how I can create a button for my work in progress app

Where do you want to create the button ? In a viewController ?
What does not work ?
1 - inserting the button in the view ?
2 - connecting the button to an IBOutlet or to an IBAction ?

For the first:
Open the storyboard in Interface Builder

• select the ViewController

• Click on + at the top right to open the objects library

• search for button

• drag and drop the button where you want in the ViewController

For the second, you should check that:

• the class defined for the ViewController in Interface Builder (in the Identity Inspector) is the class defined in the code for the class

• if not set the class as needed

if class is defined as

Code Block 
class MyViewController: UIViewController { }

then, the VC in IB must be of this class MyViewController

If that is not the problem, please explicit precisely the problem, what you try, what you expect, what you get, with a detailed sequence of your actions.

Did you solve your issue ?

If so, thanks to close the thread.
If not, please explain what the problem is.
