130 - Style a Text Editor in SwiftUI

The TextEditor view in SwiftUI offers a multi-line, scrollable area for editable plain text input, making it ideal for longer forms of textual input.

Styling a TextEditor involves making it visually appealing and suitable for your application’s design. This includes setting the font, background color, foreground color and more. Additionally, you can adjust line spacing and alignment to ensure the text is easy to read and well presented.

Let’s see how this works by with a TextEditor that contains an excerpt from Shakespeare’s Henry V:

struct ContentView: View {
  @State private var text = """
    This day is called the feast of Crispian:
    He that outlives this day, and comes safe home,
    Will stand a tip-toe when the day is named,
    And rouse him at the name of Crispian.
    He that shall live this day, and see old age,
    Will yearly on the vigil feast his neighbours,
    And say ‘To-morrow is Saint Crispian:’
    Then will he strip his sleeve and show his scars.
    And say ‘These wounds I had on Crispin’s day.’
    Old men forget: yet all shall be forgot,
    But he’ll remember with advantages
    What feats he did that day: then shall our names.
    Familiar in his mouth as household words
    Harry the king, Bedford and Exeter,
    Warwick and Talbot, Salisbury and Gloucester,
    Be in their flowing cups freshly remember’d.
    This story shall the good man teach his son;
    And Crispin Crispian shall ne’er go by,
    From this day to the ending of the world,
    But we in it shall be remember’d;
    We few, we happy few, we band of brothers;
    For he to-day that sheds his blood with me
    Shall be my brother; be he ne’er so vile,
    This day shall gentle his condition:
    And gentlemen in England now a-bed
    Shall think themselves accursed they were not here,
    And hold their manhoods cheap whiles any speaks
    That fought with us upon Saint Crispin’s day.
    """

  var body: some View {
    TextEditor(text: $text)
      .font(.system(size: 16))
      .foregroundColor(.blue)
      .padding()
      .background(.yellow)
      .cornerRadius(10)
      .lineSpacing(10)
      .multilineTextAlignment(.leading)
      .padding()
  }
}

Here’s what your preview should look like:

A styled TextEditor in SwiftUI.

In this example:

• .font(.system(size: 16)) sets the font size to 16.

• .foregroundColor(.blue) sets the text color to blue.

• .background(.yellow) sets the background color to yellow.

• .cornerRadius(10) rounds the corners of the TextEditor’s background.

• .lineSpacing(10) sets the line spacing to 10 points.

• .multilineTextAlignment(.leading) aligns the text to the leading edge (left for left-to-right languages).

• .padding() adds padding around the TextEditor.

By using these modifiers and more, you can customize a TextEditor to match the design and functionality of your app.
