ios - 如何解决 Xcode 10 beta 中的错误 "linker command failed with exit code 1 (use -v to see invocation) "？

Question

构建时失败。错误提示“/clang:-1: 链接器命令失败，退出代码 1(使用 -v 查看调用)”。我在项目中添加了一个插件unity。是否与插件有关。我考虑过这个 Link寻求解决方案。在这里我找不到任何名为 Pods 的东西。使用 Unity2018.2.1f1 和 Xcode 10 beta。我将在下面附上我在 Xcode 中的项目 View 的图像。

我从未使用过 Unity，但您的错误明确指出您的 Unity 蓝牙 LE 库中的几个符号未针对平台 arm64 定义。这意味着它不包含 arm64 的正确机器代码，这是 iPhone 使用的平台。这意味着您需要用另一个库替换库。我在 Unity Asset Store 中找到了几个蓝牙文件库。祝你使用其中任何一个好运。
