Answer 1

更新Xcode时通常会出现此类问题,但您使用的任何第三方工具都可能无法使用此体系结构进行更新armv64.

因此,从XCode单击您的Project Navigator.

Targets从项目中单击"开 ",然后单击 BuildSettings它.

找到Valid Architectures它.

只需双击它并armv64从中删除即可.

确保armv7s只有armv7 .

如果这不起作用,那么也尝试删除armv7s.

请检查所有框架是否正确链接和引用.尝试删除并再次添加该第三方工具的框架.

请检查所有框架是否正确引用.

在我的情况下,这对我有用.

清理并构建您的项目.它现在应该工作正常.

希望它能帮到你.
