Key Components of the Code

axis Property

The axis property is set to .vertical, enabling vertical scrolling within the TextField.

textFieldStyle Modifier

The .textFieldStyle(.roundedBorder) modifier adds a rounded border to the TextField, giving it a pleasing appearance.

frame Modifier

The frame height of the TextField is set to 50, defining the visible area for the input.

padding Modifier

Padding is added around the TextField to provide spacing and align the element appropriately within the view.

Advantages and Considerations

Using the axis property simplifies the creation of a scrollable TextField. It’s a straightforward approach that allows you to achieve the desired functionality without needing complex calculations or additional views.
