How do I change the function of a refresher based on the selected index of a segmentedControl

Question

I have a vc with one segmentedControl, I want to be able to change the function called by the refresher everytime the segmentedControl's index is changed

lazy var refresher: UIRefreshControl = {
    let refreshControl = UIRefreshControl()
    if (segmentedControl.selectedSegmentIndex == 0){
        refreshControl.addTarget(self, action: #selector(loadRecommend1), for: .valueChanged)
    } else if (segmentedControl.selectedSegmentIndex == 1){
        refreshControl.addTarget(self, action: #selector(loadCompletePosts1), for: .valueChanged)
    } else if (segmentedControl.selectedSegmentIndex == 2){
        refreshControl.addTarget(self, action: #selector(loadCompletePostsByHealthy1), for: .valueChanged)
    }
    return refreshControl
}()

Currently the first function is called everytime despite the selected item in the segmentedControl

This lazy var is called only once upon creation of this instance not when change of segment index , so you either change that target selector inside a 1 selector method or have only 1 selector that you execute methods according to current segment index like

refreshControl.addTarget(self, action: #selector(allCalls), for: .valueChanged)

@objc func allCalls(_ sender:UIRefreshControl) {
   if (segmentedControl.selectedSegmentIndex == 0){
        loadRecommend1()
   } else if (segmentedControl.selectedSegmentIndex == 1){
        loadCompletePosts1() 
   } else if (segmentedControl.selectedSegmentIndex == 2){
        loadCompletePostsByHealthy1() 
   }
}
