Question

每当我尝试构建应用程序重命名我的项目后，我得到一个Apple Mach-O链接器错误下面是Xcode本身的输出

感谢您的帮助，因为我是Xcode和快速语言的新手。 玩笑

Answer 1

重命名后，只需转到您的项目文件（您将看到标签：常规，功能，信息等）

并在左侧列表中选择YourAppTests

你可能会看到这张照片

将Host Application设置为您的项目名称，就是这样。

Answer 2

我在尝试实施AdMob广告时偶尔会遇到Apple Mach-O Linker Error 1 。 我处理它的方式是首先进入我的应用程序的构建设置并找到“库搜索路径”并清除所有搜索路径。 然后我将AdMob文件夹重新添加到项目中，错误消失了。

现在显然你的情况有点不同了。 就个人而言，我会将文件重命名为以前的名称。 如果错误仍然存​​在，则清除库搜索路径。 仍然是一个错误？ 我在收到错误时所做的是创建一个名为I want的新Xcode项目，然后将所有文件复制到新项目中。 这是一个简单的过程，特别是如果你是一个初学者，它可能不会花太长时间。 我希望这有帮助！
