David Smith<p>Bridging non-ASCII NSMutableStrings from ObjC will be slower at the point of bridging, *but* the String produced as a result will be much faster.</p><p>One particular case this tradeoff can end up not paying off in is if you then bridge the resulting String back to ObjC. If you're in that situation the recommendation is to not double-bridge strings if you can avoid it.</p><p>If you're in any other situation and this tradeoff is impacting your perf, please file a feedback.</p><p><a href="https://mastodon.social/tags/swiftlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>swiftlang</span></a> <a href="https://mastodon.social/tags/wwdc25" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>wwdc25</span></a> <a href="https://mastodon.social/tags/objc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>objc</span></a></p>
