Change UITextField and UITextView Cursor / Caret Color

Setting tintColor for UITextField and UITextView works differently. While for UITextField you don't need to call additional code after updating tintColor to change cursor color, but for UITextView you need.

So after setting tintColor for UITextView (it doesn't matter in IB or in code) you need to call textView.tintColorDidChange() in order to apply it (actually it will pass text view's config down to its subviews hierarchy).

I think If you want some custom colors you can go to Assets.xcassets folder, right click and select New Color Set, once you created you color you set, give it a name to reuse it.

And you can use it just like this :

import UIKit 

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        UITextField.appearance().tintColor = UIColor(named: "YOUR-COLOR-NAME")  #here
    }
}

Tested on macOS 10.15 / iOS 13 / Swift 5

For people searching the equivalent in SwiftUI for Textfield this is accentColor:

TextField("Label", text: $self.textToBind).accentColor(Color.red)

If the UITextField is from UISearchBar then first get the textField from searchBar and then apply tintColor property:

let textFieldInsideSearchBar = searchBar.value(forKey: "searchField") as? UITextField
textFieldInsideSearchBar?.tintColor = UIColor.lightGray

Swift 4

In viewDidLoad() just call below code:

CODE SAMPLE

//txtVComplaint is a textView

txtVComplaint.tintColor = UIColor.white

txtVComplaint.tintColorDidChange()
