启动 HN：Bitrig（YC S25） – 在你的 iPhone 上构建 Swift 应用程序
嗨，HN，我们是Kyle、Jacob和Tim。我们正在开发Bitrig（<a href="https://www.bitrig.app">https://www.bitrig.app</a>）。<p>Bitrig让你可以在手机上通过与AI聊天来创建原生Swift应用。这就像是为iPhone应用而设计的Lovable。<p>这是Bitrig实际操作的视频：
<a href="https://youtu.be/CUlWhF3ERME" rel="nofollow">https://youtu.be/CUlWhF3ERME</a><p>我们在Apple创建了SwiftUI，以帮助开发者用更少的代码制作更好的应用。Bitrig让任何人都能以这种精致的水平进行开发。如果你曾考虑过制作iPhone应用，Bitrig是开始使用Swift的最简单方式。<p>Bitrig使用Claude Sonnet 4.0，通过简单的系统提示和工具定义来生成原生Swift代码。通常在iPhone上运行这段代码需要使用Xcode进行编译和签名，而你无法在iPhone上运行Xcode。因此，我们做了一些……创造性的事情。我们编写了一个自定义的Swift解释器！这使得你可以立即在Bitrig中预览你的应用，并通过一个URL分享它。<p>如果你拥有一个付费的Apple开发者账户，可以将其与Bitrig连接。我们将在我们的服务器上编译你的应用，并将其上传到App Store Connect，这样你就可以在TestFlight或App Store上分发它。最后一步还会为你的应用提供一个完全优化的构建版本，你可以直接安装在主屏幕上。<p>我们认为在手机上直接构建应用是非常激动人心的。希望你能试试Bitrig！<p>我们正在逐步将Apple的SDK框架引入Bitrig。如果你尝试构建某个东西时遇到缺失的框架，请告诉我们，我们会优先添加它。<p>在App Store下载Bitrig：

Hi HN, we’re Kyle, Jacob, and Tim. We’re building Bitrig (<a href="https://www.bitrig.app">https://www.bitrig.app</a>).<p>Bitrig lets you create native Swift apps for your phone, on your phone, just by chatting with AI. It’s like Lovable for iPhone apps.<p>Here's a video of Bitrig in action:
<a href="https://youtu.be/CUlWhF3ERME" rel="nofollow">https://youtu.be/CUlWhF3ERME</a><p>We created SwiftUI at Apple to help developers make better apps with less code. Bitrig lets anyone build at this level of polish. If you've thought about making an iPhone app, Bitrig is the easiest possible way to get started with Swift.<p>Bitrig uses Claude Sonnet 4.0 with a simple system prompt and tool definitions to generate native Swift code. Normally running this on an iPhone would require compiling and signing it with Xcode, and you can’t run Xcode on an iPhone. So we did something… creative. We wrote a custom Swift interpreter! Among other things this lets you instantly preview your app in Bitrig and share it with just a URL.<p>If you have a paid Apple developer account, you can connect it with Bitrig. We’ll compile your app on our server and upload it to App Store Connect, so you can distribute it on TestFlight or the App Store. This last step also gives you a fully optimized build of your app that you can install right on your Home Screen.<p>We think there’s something electric about building apps directly on your phone. We hope you give Bitrig a try!<p>We’re ingesting Apple’s SDK frameworks into Bitrig piece by piece. If you try to build something and hit a missing framework, let us know and we’ll prioritize adding it.<p>Download Bitrig on the App Store:
