Custom TextField Menu Actions | SwiftUI

[@Kavsoft]

To make a TextField with the axis property functional,
1. You need to change the UITextFieldDelegate to UITextViewDelegate.
2. Change the below code,
func textField(_ textField: UITextField, editMenuForCharactersIn range: NSRange, suggestedActions: [UIMenuElement]) -> UIMenu?
to this:
func textView(_ textView: UITextView, editMenuForTextIn range: NSRange, suggestedActions: [UIMenuElement]) -> UIMenu?
3. Add these code block into the Coordinator,
var originalDelegate: UITextViewDelegate?
func textViewDidChangeSelection(_ textView: UITextView) {
originalDelegate?.textViewDidChangeSelection?(textView)
}
func textViewDidChange(_ textView: UITextView) {
originalDelegate?.textViewDidChange?(textView)
}
5. Change TextFieldAction callback from this:
var action: (NSRange, UITextField) -> ()
to this:
var action: (NSRange, UITextView) -> ()
6. Finally modify the makeUI view code block to this,
DispatchQueue.main.async {
if let textView = view.superview?.superview?.subviews.last?.subviews.first as? UITextView {
context.coordinator.originalDelegate = textView.delegate
textView.delegate = context.coordinator
}
}
After making all these adjustments, the TextField with the axis property will function correctly.

Traversal to find a particular view is dangerous, because the internal view composition of each system version is inconsistent

Yes, that’s the reason I restricted the custom modifier to TextField only and prevented any view customizations on it. Without any view customizations (modifiers), it will always result in the same view. I also used the compostingGroup modifier to ensure the result!
