构建 Unity3D iPhone 项目时 Xcode 链接器失败

Question

Unity 能够构建 Xcode 项目，但是当我将项目构建到我的 iPhone 时，它​​会抛出 50 个警告（我听说这对 Unity 项目来说很好）并且它在链接器处失败。

似乎图书馆的参考资料搞砸了。尝试删除引用并再次添加。有关如何执行此操作和其他建议的更多信息，请参阅这些类似问题。

Error "library not found for"

XCode linker error : library not found for -lAdMobDevice

Answer 2

在“Unity --> Edit --> Project Settings --> Player --> iOS Settings --> Other Settings --> Target minimum iOS Version”中将最低iOS版本更新为较新版本（在我的情况下为12.0 ) 并修复 Unity 版本“Unity Dashboard --> Cloud Build --> Config --> in iOS profile --> Basic Info Unity version”（在我的情况下为 2021.2.0b13）。 这解决了我的问题。
