Usage

SwiftUI

The Swift Package product NextGrowingTextViewSwiftUI provides a pure SwiftUI implementation for iOS 17 and later. It measures a hidden TextEditor with the same font, line spacing, and padding as the visible editor, then applies the measured height to the visible editor.

import NextGrowingTextViewSwiftUI

@State private var text = ""

GrowingTextEditor(
  text: $text,
  placeholder: "Write something...",
  configuration: GrowingTextEditorConfiguration(
    minLines: 1,
    maxLines: 6,
    horizontalPadding: 8,
    verticalPadding: 4,
    lineSpacing: 3
  ),
  font: .body
)

GrowingTextView is also available as a typealias when call sites prefer the TextView naming.

UIKit

Use the NextGrowingTextView product when you need a UIKit UIView backed by UITextView. Configure the line limits, style the inner textView, and set up the placeholder label to match your design.

import NextGrowingTextView
import UIKit

let growingTextView = NextGrowingTextView()

growingTextView.configuration = .init(
  minLines: 1,
  maxLines: 6,
  isAutomaticScrollToBottomEnabled: true,
  isFlashScrollIndicatorsEnabled: true
)

growingTextView.textView.font = .preferredFont(forTextStyle: .body)
growingTextView.placeholderLabel.text = "Write something..."
growingTextView.placeholderLabel.font = growingTextView.textView.font
growingTextView.placeholderLabel.textColor = .placeholderText

growingTextView.actionHandler = { action in
  switch action {
  case .willChangeHeight(let newHeight):
    print("Will change height:", newHeight)
  case .didChangeHeight(let newHeight):
    print("Did change height:", newHeight)
  case .didChangeState:
    break
  }
}
