Nested callback function not working properly swift
I am trying to implement nested completion handlers but for some reason, my second handler is not firing upon completion. This is how the code looks like
//User presses a button on a cell. Code is in `cellForRowAtIndex...`
cell.callback = {
print("in CFRAIP")
self.showPopUpDialog(completionHandler: { () -> Void in
print("AfterPOPUPDIALOG")
self.requestBookingWithCompletionHandler(fetchBookingForDate: self.currentDate, row: indexPath.row)
})
}
func showPopUpDialog(completionHandler: () -> Void ){
print("In show PopUPdialog")
let alertController = UIAlertController(title: "Uppgifter", message: "Skriv in namn och telefonnummer", preferredStyle: .alert)
let confirmAction = UIAlertAction(title: "Boka", style: .default) { (_) in
//getting the input values from user
self.bokadNamn = (alertController.textFields?[0].text)!
self.bokadTelefon = (alertController.textFields?[1].text)!
print("pressed ok in popup")
}
let cancelAction = UIAlertAction(title: "Avbryt", style: .cancel) { (_) in}
//adding textfields to our dialog box
alertController.addTextField { (textField) in
textField.placeholder = "Namn"
textField.layer.cornerRadius = 5
}
alertController.addTextField { (textField) in
textField.placeholder = "Telefonnummer"
}
alertController.addAction(confirmAction)
alertController.addAction(cancelAction)
//finally presenting the dialog box
self.present(alertController, animated: true, completion: nil)
}
This is the prints that I am getting:
in CFRAIP
In show PopUPdialog
pressed ok in popup
print("AfterPOPUPDIALOG")
is not being fired and my network request is not being run after the user pressed ok in the PopUP
. I feel like it is something really simple that I am missing but unfortunately, I am to blind to see it...

Inside the function func showPopUpDialog(completionHandler: () -> Void ) {
, you are not calling the completion handler completionHandler
anywhere.
If you will not call your completion handler, how will print statement print("AfterPOPUPDIALOG")
be executed?
Call your completion handler completionHandler
at the appropriate place.
Wow.. Haha i am really too tired. Thank you
