TextView capitalizes first two characters instead of one - swift

Question

So I've added placeholder functionality to UITextView, and now it capitalizes the first two characters of input text instead of one as it's supposed to.
I would appreciate you guys' help in solving this problem if you can help in any way. I've been trying, but I seem to be getting nowhere.
Here's the code:
class ViewController: UIViewController {
#IBOutlet weak var textView: UITextView!
override func viewDidLoad() {
super.viewDidLoad()
textView.delegate = self
textView.text = "Type something"
textView.textColor = UIColor.rgb(197, 197, 199)
}
}
extension ViewController: UITextViewDelegate {
// Put cursor at the beginning of TextView when editing begins
func textViewDidBeginEditing(_ textView: UITextView) {
textView.selectedTextRange = textView.textRange(from: textView.beginningOfDocument, to: textView.beginningOfDocument)
}
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
// Sets placeholder for UITextView
let updatedText = (textView.text as NSString).replacingCharacters(in: range, with: text)
if updatedText.isEmpty {
textView.text = "Type something"
textView.textColor = UIColor.rgb(197, 197, 199)
textView.selectedTextRange = textView.textRange(from: textView.beginningOfDocument, to: textView.beginningOfDocument)
} else if textView.textColor == UIColor.rgb(197, 197, 199) && !text.isEmpty {
textView.textColor = UIColor.black
textView.text = text
} else {
return true
}
return false
}
// Prevents selecting the placeholder
func textViewDidChangeSelection(_ textView: UITextView) {
if self.view.window != nil {
if textView.textColor == UIColor.rgb(197, 197, 199) {
textView.selectedTextRange = textView.textRange(from: textView.beginningOfDocument, to: textView.beginningOfDocument)
}
}
}
}
Thank you!

The code below solves capitalization of the first 2 letters in text view.
func textViewDidChange(_ textView: UITextView) {
if textView.text.isEmpty {
textView.text = "Type something"
textView.textColor = self.placeholderTextColor
} else {
textView.textColor = .black
}
}
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
if text.isEmpty {
let updatedText = (textView.text as NSString).replacingCharacters(in: range, with: text)
if updatedText.isEmpty {
textView.text = "Type something"
textView.textColor = self.placeholderTextColor
textView.selectedRange = NSRange(location: 0, length: 0)
}
} else {
if textView.text == "Type something" {
textView.text = ""
}
textView.textColor = .black
}
return true
}
The reason why the text view capitalized first 2 characters in text view is that you've returned false in below delegate method
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool
