UITextPosition to Int

Question

I have a UISearchBar on which I am trying to set a cursor position. I am using UITectField delegates as I couldn't find anything direct for UISearchBar. Below is the code I am using:

  UITextField *textField = [searchBar valueForKey: @"_searchField"];
  // Get current selected range , this example assumes is an insertion point or empty selection
  UITextRange *selectedRange = [textField selectedTextRange];
  // Construct a new range using the object that adopts the UITextInput, our textfield
  UITextRange *newRange = [textField textRangeFromPosition:selectedRange.start toPosition:selectedRange.end];

Question is in the 'newRange' object for 'toPosition' I want to have something like selectedRange.end-1; as I want the cursor to be on second last position.

How do I set the cursor to second last position?

Swift 5

I came across this question originally because I was wondering how to convert UITextPosition to an Int (based on your title). So that is what I will answer here.

You can get an Int for the current text position like this:

if let selectedRange = textField.selectedTextRange {
    // cursorPosition is an Int
    let cursorPosition = textField.offset(from: textField.beginningOfDocument, to: selectedRange.start)
}

Note: The properties and functions used above are available on types that implement the UITextInput protocol so if textView was a UITextView object, you could replace the instances of textField with textView and it would work similarly.

For setting the cursor position and other related tasks, see my fuller answer.
