SwiftUI, Apple’s latest UI framework, allows developers to design apps in a declarative way, making it much simpler and intuitive to work with. It brings new approach to UI design with its innovative and simple language constructs. One of the straightforward yet crucial components in SwiftUI is TextField, an input field that allows users to enter text through a keyboard. In this article, we will delve into what makes TextField in SwiftUI unique, how to custom style it, and the possible challenges you may encounter along the way.
SwiftUI TextField, by default, comes with a minimalistic design, which may not cater to everyone’s taste. It might not suit the overall theme of your app, or perhaps you want to give it a unique feel to set your app apart from others. But fret not, SwiftUI also empowers us to customize TextField according to our needs.
Styling TextField in SwiftUI
To start styling your TextField component, you’ll first need to create a struct conforming to the TextFieldStyle protocol. In the style configuration, you can modify several properties, such as background color, font style, border, and so on, to match your desire.
struct CustomTextFieldStyle: TextFieldStyle {
func _body(configuration: TextField<Self._Label>) -> some View {
configuration
.font(.custom("Helvetica", size: 20))
.padding()
.background(Color.white)
.cornerRadius(10)
.shadow(radius: 5)
}
}
The above custom TextField style uses Helvetica font of size 20, has padding for better appearance, a white background, corner radius for rounded corners, and a slight shadow for 3D effect.
Applying the custom style
To apply the custom style that we’ve created to our TextField, all we have to do is use the .textFieldStyle modifier and pass the custom style struct.
TextField("Enter text here...", text: $inputText)
.textFieldStyle(CustomTextFieldStyle())
With just these lines of code, you have now given your TextField a fresh look!
It’s imperative to understand that SwiftUI, with its straightforward and flexible approach, has opened up endless possibilities for developers to create unique, eye-catching user interfaces with relative ease. As of now, there are some limitations and we might encounter challenges as we experiment more, but the SwiftUI team is steadily working on the updates and it is out of doubt that SwiftUI is the future of iOS app development.
Libraries and Functions Related to TextField Styling
Although SwiftUI does not mandate the usage of any external libraries for TextField styling, developers can utilize libraries like `SwiftUIX` for more functionalities. Equipped with broader styling options, it can help accomplish more complex designs with ease.
To further enhance your TextField, SwiftUI gives you access to built-in functions like .keyboardType(), .autocapitalization() or .disableAutocorrection(), providing you with more control over user input.

Advanced TextField Styles
SwiftUI TextField also supports multiline text input, password fields, and placeholder text to cater to various needs.
SecureField("Placeholder text", text: $password)
//For password input- text will be concealed
TextField("Placeholder text", text: $inputText)
.multilineTextAlignment(.center)
//For multiline input, with centered text
While SwiftUI does provide a host of customization options for TextField, but when it comes to a heavily customized TextField, you might find it challenging as SwiftUI is still evolving.
However, with SwiftUI’s continuous updates and enhancements, it’s safe to say the horizon of what’s possible with SwiftUI is ever-expanding. Thus, mastering SwiftUI and its components, like TextField, would be a lucrative skill for any iOS app developer.
