在遇到可怕的问题后，我通过将我的项目传递给另一个项目来完成。但是现在它在尝试运行我的程序后给了我这个错误。这是我以前从未见过的。而且，我没有编辑这些代码，因为它们是库。

我使用 flutter 构建了一个应用程序，现在我想通过 Xcode 将其部署到我的 iPhone 上。但是，当我使用调试配置进行部署时，当我将手机与 Mac 断开连接时，我不会在手机上访问我的应用程序。所以我搜索并发现我应该在发布配置中构建，但是当我这样做时，我会收到这样的弹出窗口

我输入了唯一的用户密码，但它被拒绝了。我搜索并发现按“始终允许”工作正常，但就我而言，没有此选项。我应该怎么办？谢谢。

自从我将项目迁移到 Apple Silicon mac 后，我遇到了许多问题。我终于设法减少了问题，但不确定答案。

我正在尝试将频率值转换为注释，例如输入 400 Hz 打印“A4”，但我不想在代码中编写完整的频率表。有什么办法可以做到这一点吗？

我正在使用 m1 MacBook pro 并尝试在 ESP8266 上运行 arduino 代码。每次它都会给我这个错误

我知道关于这个问题有很多类似的问题，我都尝试了，但没有成功。\n尝试在物理设备上的 Xcode 上运行代码后开始出现问题。\n错误如下我在命令中所说的那样线路“颤振运行”。
