Spacer, Padding and Frame Modifiers

Using Spacer for flexible gaps and frame to set explicit sizes.

Spacer, Padding and Frame Modifiers is a free Swift Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Swift Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.

Welcome

`Spacer`, `.padding()`, and `.frame()` are the primary tools for controlling spacing and sizing in SwiftUI. Let's master each.

Spacer — Flexible Space

```swift HStack { Text("Left") Spacer() // fills all available space Text("Right") } ``` `Spacer` expands to fill remaining space along the stack axis.

Minimum Length

```swift Spacer(minLength: 20) // at least 20pt even if compressed ```

.padding() Modifier

```swift Text("Hello") .padding() // default 16pt all sides .padding(.horizontal, 24) // custom horizontal .padding(.top, 8) // custom top only ```

.padding with EdgeInsets

```swift Text("Hi") .padding(EdgeInsets(top:10,leading:20,bottom:10,trailing:20)) ```

.frame() — Explicit Size

```swift Text("Button") .frame(width: 200, height: 44) .background(Color.blue) .foregroundColor(.white) ```

.frame(maxWidth:)

```swift Button("Full Width") {} .frame(maxWidth: .infinity) .padding() .background(Color.accentColor) ```

.frame(alignment:)

```swift Text("Left") .frame(width: 200, alignment: .leading) .border(Color.gray) // Text aligns left within the 200pt wide frame ```

fixedSize

```swift Text("Long text that should not wrap") .fixedSize() // prevents truncation / wrapping ```

Combining Spacer + Frame

```swift VStack { Spacer() Text("Bottom") .frame(maxWidth: .infinity) .padding() } ```

Recap

Key takeaways: • `Spacer()` fills available space; `Spacer(minLength:)` for a minimum gap • `.padding()` adds insets; specify edge and amount for precision • `.frame(width:height:)` sets fixed size • `.frame(maxWidth: .infinity)` expands to fill • `.fixedSize()` prevents truncation Next: GeometryReader.
