Personally, I prefer to add a custom extension to Binding so that I attach observing code directly to the binding rather than to the view – it lets me place the observer next to the thing it’s observing, rather than having lots of onChange() modifiers attached elsewhere in my view. Important: If you’re using Xcode 12 you need to use RoundedBorderTextFieldStyle() rather than. SwiftUI’s TextField supports placeholder text just like UITextField did gray text that is shown in the text field when it’s empty, either giving users a prompt (Enter your password) or showing some example data.

We need to style our TextField better so it can be visible. Select the text field -> click 'identity inspector' icon -> click on Plus button 'user Defined runtime attributes' -> add this text 'placeholderLabel. To achieve this, you can create a new color set in the Assets.xcassets folder. The above mockup uses systemIndigo, but I want to have a darker color for the light mode and a lighter color for the dark mode.

There is no direct way to add palce holder. SwiftUI’s TextField view is similar to UITextField in UIKit, although it looks a little different by default and relies very heavily on binding to state. SwiftUI lets us attach an onChange() modifier to any view, which will run code of our choosing when some state changes in our program. .foregroundColor actually does change the text color of TextField but only when it has a default value, for example this will work fine: TextField(.constant('Hello World'), placeholder: Text('Type here.')). Even setting background color, changing text cursor color is not straight forward.
