ios - Flutter_tts 无法在 iOS 上运行

Question

我正在尝试使用 Flutter_tts 编写一个在 flutter 上朗读文本的应用程序库，它在 Android 上运行良好，但是当我尝试在 iOS 设备上运行它时，出现错误:

 === BUILD TARGET Runner OF PROJECT Runner WITH CONFIGURATION Debug ===
    ld: warning: Could not find auto-linked library 'swiftDispatch'
    ld: warning: Could not find auto-linked library 'swiftCoreMedia'
    ld: warning: Could not find auto-linked library 'swiftAVFoundation'
    ld: warning: Could not find auto-linked library 'swiftFoundation'
    ld: warning: Could not find auto-linked library 'swiftsimd'
    ld: warning: Could not find auto-linked library 'swiftObjectiveC'
    ld: warning: Could not find auto-linked library 'swiftCoreFoundation'
...

我之前将构建系统切换为旧版构建系统，并将“Swift 语言版本”指定为“Swift 4.2”

当我将构建系统切换到“新构建系统”时，它给了我

Xcode's output:
↳

降级 Swift 版本也没有帮助。

我还能尝试什么来解决这个问题？ 或者也许你可以推荐另一个库？(我已经尝试过 Tts ，它看起来不是一个好的选择，因为它仅适用于 flutter v"0.5.0"(Dart 版本 2.0.0<)

I also get this warning when I open Xcode

这是在不使用 -i swift 标志创建 flutter 项目时的一个已知问题。我在这里概述了similar issue

flutter create -i swift my_app

作为一个可怕的解决方法，您可以使用 -i swift 标志创建一个新的 flutter 项目，并从当前项目复制文件。
