How to make custom controller for View in iOS

Issue #318

I do UI in code, and usually separate between View and ViewController.

class ProfileView: UIView {}

class ProfileViewController: UIViewController {
	override func loadView() {
        self.view = ProfileView()
    }
}

But in places where using UIViewController and manage their view controller containment hierarchy is not desired, then we can roll out a normal object to act as the controller.

class ProfileController {
  let profileView: ProfileView
  
  init(profileView: ProfileView) {
    self.profileView = profileView
  }

  func update(profile: Profile) {
    profileView.nameLabel.text = profile.name
  }
}

If the name Controller sounds confusing with UIViewController, I usually use Handler, which contains other Handler to handle logic for view
