Create a multi-line, editable textual content view utilizing TextEditor in SwiftUI. – iOSTutorialJunction

In UIKit, we use UITextView for enter fields that require lengthy textual content entries from the consumer. In SwiftUI, we will accomplish the identical with TextEditor. The TextEditor view in SwiftUI handles multiline textual content enter. On this tutorial, we’ll learn to use TextEditor with a placeholder, making it perform equally to a UITextView in UIKit.

Step-by-Step Implementation of multi-line editable textual content area in SwiftUI

Step 1: Open Xcode and choose “Create a brand new Xcode undertaking.“. Select “App” beneath the iOS tab.Identify your undertaking and ensure “SwiftUI” is chosen for the Consumer Interface.

Step 2: Create a state variable named multiLineText.

import SwiftUI

struct FeedbackView: View {
   @State non-public var multiLineText = ""
   var physique: some View {
   }

}

Step 3: Let begin designing our multi-line textual content area in SwiftUI utilizing TextEditor.

• First we’ll take VStack with alignment to main as we would like our view to to not be in centre of display however towards the forefront.
• Add a Textual content view with title “Remark” illustrating consumer the he can add feedback beneath
• Take a ZStack with alignment to topLeading and inside it first we’ll add a RoundedRectangle view in order that we can provide border to our TextEditor. Then will test if state variable named multiLineText is empty or not. If it’s empty we’ll add placeholder textual content utilizing Textual content view.
• Lastly we’ll add TextEditor to our ZStack. Lastly we’ll change opacity of TextEditor if it’s empty in an effort to let placeholder Textual content seen to consumer.

Full code snippet is given beneath.

import SwiftUI

struct ContentView: View {
    @State non-public var multiLineText = ""
    var physique: some View {
        VStack(alignment: .main) {
            Textual content("Remark")
                .font(.system(measurement: 14.0, weight: .medium))
            ZStack(alignment: .topLeading) {
                RoundedRectangle(cornerRadius: 14, model: .steady)
                    .strokeBorder(Coloration.crimson.opacity(0.6), lineWidth: 1)
                if multiLineText.isEmpty {
                    Textual content("Placeholder Textual content")
                        .foregroundColor(Coloration.grey)
                        .font(.system(measurement: 14.0, weight: .common))
                        .padding(.horizontal, 8)
                        .padding(.vertical, 12)
                }
                TextEditor(textual content: $multiLineText)
                    .font(.system(measurement: 14.0))
                    .opacity(multiLineText.isEmpty ? 0.7 : 1)
                    .padding(4)
                
            }
            .body(top: 135)
        }
        .padding()
    }
}

#Preview {
    ContentView()
}
