Make the TextField Multiline - SwiftUI

Question

I start learning SwiftUI and I'm trying to make the TextField multiline but it didn't work, also when I click on the return button it dismisses the keyboard.

TextField("Description", text: $categoryTitle)
.lineLimit(nil)

so how I can fix it?

Answer 1

Since iOS 16

The lineLimit modifier works as expected if you choose .vertical value for the axis parameter. And it also supports range now:

TextField("Title", text: $text, axis: .vertical)
    .lineLimit(5...10)

Since iOS 14

Form iOS 14 and with Xcode 12, it's available as TextEditor

struct ContentView: View {
    @State var text: String = "Multiline \ntext \nis called \nTextEditor"

    var body: some View {
        TextEditor(text: $text)
    }
}

iOS 13

Also, if you want to support iOS 13, you can take at look this answer to port UITextField inside SwiftUI with full access to all of its properties.
