Hello everyone,

The [review](https://forums.swift.org/t/se-0477-default-value-in-string-interpolations/79302) of [SE-0477: Default Value in String Interpolations](https://github.com/swiftlang/swift-evolution/blob/main/proposals/0477-default-interpolation-values.md) ended on April 29, 2025.

Feedback during the review was positive overall. The proposal author agreed with a suggestion to change the type of the `default` parameter to `@autoclosure () -> some StringProtocol`, with the understanding that it would be straightforwardly optimizable. The language steering group agreed that the proposal should be **accepted with that modification**.

Thank you, as always, to all participants in this review process for helping to make Swift a better language.
