How to bold text in TextField swiftUI?

A general approach for using standard font size options and weights that work with SwiftUI TextField. For example:

TextField("Name", text: $name)
  .font(Font.headline.weight(.light))

Available standard size options (smallest to largest):

.caption
.footnote
.subheadline
.callout
.body
.headline
.title
.largeTitle

Available standard font weights (lightest to heaviest):

.ultralight
.thin
.light
.regular
.medium
.semibold
.bold
.heavy
.black

import SwiftUI

struct ContentView: View {
    @State var TextValue: String = "Hello"

    var body: some View {
        VStack {
            TextField("placeholder", text: $TextValue)
            .padding(.horizontal, 50)
                .font(.system(size: 30, weight: .heavy, design: .default))
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

TextField("Name", text: $name)
    .font(Font.body.bold())
