我在 Swift 中的 segue 代码有什么问题？

Question

I'm trying to segue into a 'settings' View Controller by clicking a button, and I'm assembling it via code but don't know what I'm doing wrong.

This is my button code:

 @IBAction func settingsButton(_ sender: UIButton) {

        self.performSegue(withIdentifier: "SettingsViewController", sender: self)
    }

The View Controller is called 'Settings View Controller' (unsurprisingly). The app crashes whenever I press on it in my Simulator.

It'll probably be a simple thing, but any ideas what I'm doing wrong?

Answer 1

You must set your segue identifier whatever you want (for your question = SettingsViewController ) from storyboard:
