SwiftUI Gotcha - fixedSize Modifier

The fixedSize modifier in SwiftUI forces a view to adopt its ideal size, preventing it from being compressed or truncated.

For example, you can use it to make sure a long text isn’t cut off:

Text(aVeryLongString)
    .fixedSize(horizontal: false, vertical: true)

However, there’s a subtle gotcha: the lineLimit modifier takes precedence over fixedSize. If a lineLimit is applied anywhere in the view hierarchy and affects the text view, it will still truncate the text — even if fixedSize is used.

To avoid this, make sure no unintended lineLimit is affecting your text. A simple fix is to explicitly set .lineLimit(nil) on the Text view alongside fixedSize:

Text(aVeryLongString)
    .lineLimit(nil)
    .fixedSize(horizontal: false, vertical: true)

This ensures the text can grow vertically to fit its content as expected.
