Why doesn't Xcode see the Swift class in the compiled framework?

Question

Objective-C

There is a task - to make several Swift classes in the form of a compiled framework.
There is a project on github showing how to create a framework containing a swift class - https://github.com/crspybits/CocoaTouchFramework .
In the example of this project, the connection of the framework goes through importing the xcode project.
I created a new swift project and added the already compiled SimpleFramework.framework there from the above mentioned repository and got an error:

ViewController.swift:12:22: 'SimpleClass' is unavailable: cannot find Swift declaration for this class

That is, xcode does not see the SimpleClass class. What's wrong?

//
//  ViewController.swift
//

import UIKit
import SimpleFramework

@objc class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        var object = SimpleClass("fwe")

    }

}
