I am studying Swift! I want create Main interface on xib. But have error "use of unresolved identifier".
Add code from MainViewController
import Foundation
public class MainViewController : BaseViewController {
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
// TODO: Write your test code here
// ...
} }
1) Right Click your MainViewController.swift
2) Select Show File Inspector
3) On Right side panel, look at Target Membership
4) Add your class to target by check the box :)
