ios - 由于重复符号错误，GoogleAnalytics 无法在 Xcode 10 beta 5 上编译
<p><p>在 Xcode 10 beta 5 上构建包含 GoogleAnalytics 库的项目在链接期间由于 GoogleAnalytics 库的重复符号错误而失败。</p>
<p>这不是 CocoaPods 的问题，手动集成 GoogleAnalytics 也会失败并出现相同的错误。同样的问题也发生在其他二进制分布式库(CardIO、Crashlytics、Fabric)上。根据 Apple 的链接器工程师的说法，这不是错误，而是 Xcode 10 beta 5 中修复的错误。该修复无法与使用 10b5 之前的旧 Xcode 构建的损坏的静态库互操作，并且尽可能提供最佳解决方案是用较新版本的 Xcode 编译这些库(我在 CardIO 上遇到了同样的问题，并且通过使用 Xcode 10b5 重新编译它成功地修复了它)。</p>
<p>由于 GoogleAnalytics 是封闭源代码，因此我无能为力。任何 GoogleAnalytics 维护人员都可以使用最新的 Xcode 重新编译它并发布新版本吗？</p>
