Don't you wish UIRefreshControl used blocks? Don't you wish you could add one to a TableView with one line of code?

UITableView+Helpers.swift

import UIKit

class BlockRefreshControl: UIRefreshControl {
    private let block: ()->()
    
    init(block: @escaping ()->()) {
        self.block = block
        super.init()
        addTarget(self, action: #selector(BlockRefreshControl.peformBlock), for: .valueChanged)
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    @objc private func peformBlock() {
        block()
    }
    
}

extension UITableView {
    
    @discardableResult func addRefreshControl(withAction action: @escaping ()->()) -> UIRefreshControl {
        let control = BlockRefreshControl(block: action)
        
        if #available(iOS 10.0, *) {
            refreshControl = control
        } else {
            backgroundView = control
        }
        
        return control
    }
    
}

//Example usage

tableView.addRefreshControl { [weak self] in
	self?.presenter.forceUpdate()
}
