如何快速将元素添加到新的 UIViewController？

Question

i have been trying to insert a element into my new view controller when this happened:

For those of you who had the image not load, it said Could not insert new action connection: Could not find any information for the class named ProfileViewController. ProfileViewController is the name of the ViewController. Here is my code for the ViewController:

import UIKit
class ProfileViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
}

It was a cocoa touch class with Firebase and Cocoapods. Here is main.storyboard:

Answer 1

Did you enter the name of your class ( ProfileViewController ) in the "Class" portion of your storyboard? See the image for reference. (This is found on the right pane of Xcode)

Also, I do not see any IBOutlet/IBAction properties in your ViewController which are required for any connection between your storyboard and your code.

If the issue is that you're unable to add an IBOutlet/IBAction, then I would recommend cleaning your project (Product > Clean) and removing DerivedData, then trying again.
