Meet the Text View
The Text view is how you put words on screen. It is the simplest, most-used view in all of SwiftUI. ✍️
Your First Text
Create a Text view by passing a string in parentheses. SwiftUI shows exactly what you put inside the quotes.
Text("Hello, SwiftUI!")Text Lives in the body
You place a Text view inside your view's body, and it appears centered on screen by default.
var body: some View {
Text("Welcome aboard")
}Showing a Variable
You can pass a variable instead of a literal. The text updates automatically to match the value you give it.
let name = "Sam"
Text(name)String Interpolation
Mix values into a string with interpolation using a backslash and parentheses. It is perfect for greetings and counts.
let count = 3
Text("You have \(count) tasks")Making Text Bigger
Use the font modifier to change size. Apple gives you semantic sizes like title and headline that adapt nicely.
Text("Big News")
.font(.title)Bold and Heavy Text
Add weight with the bold modifier to make important words stand out from the rest.
Text("Important")
.bold()Coloring Your Text
Change the color with foregroundStyle. Pick a system color like blue or red, or use your own.
Text("On sale")
.foregroundStyle(.red)Text Is Smart About Size
A Text view sizes itself to fit its words. It takes only the space it needs, never more, unless you tell it otherwise.
Empty and Long Text
An empty string shows nothing, and very long text wraps onto multiple lines automatically. Text is forgiving by default. 👍
Text Stays Localizable
A plain string literal in Text is treated as a localized key. This makes translating your app later much easier. 🌍
Quick Check
Let's check how you put a custom color on text.
Recap: Displaying Text
The Text view shows strings, variables, and interpolated values. Style it with font, bold, and foregroundStyle, and it sizes itself automatically. 🎉
