Could not insert new outlet collection Xcode

Question

I am currently using the new Xcode Version 9 Beta 5 and Swift 4. I tried to start a new application using the "Single View Application" (it did not automatically come with a View Controller File, only the usual Info.plist, Main storyboard, Assets xcassets, LaunchScreen.storyboard)

As there is no View Controller file, I created one and tried to segue an image view but I got the error below instead.

Could someone help me with this?

1. Open Main.storyboard,
2. Select the View Controller,
3. Open the Identity Inspector,
4. In the class, choose the ViewController.swift file you created. Then try again creating the outlet
