Answer 1

此类问题通常发生在更新您的 Xcode 时，但您使用的任何第三方工具可能无法使用此架构 armv64 进行更新。

因此，从 XCode 中单击您的项目导航器。

从您的项目中单击Targets，然后从中单击BuildSettings。

在其中找到Valid Architectures。

只需双击它并从中删除 armv64。

确保只有 armv7 和 armv7s。

如果这不起作用，那么也尝试删除 armv7s。

请检查您的所有框架是否已正确链接和引用。尝试删除并再次添加该第三方工具的框架。

请检查是否正确引用了所有框架。

就我而言，这对我有用。

清理并构建您的项目。现在应该可以正常工作了。

希望对你有帮助。
