ios - 添加 Realm Cocoapod 时重复符号
<p><p>我第一次尝试在实际项目中使用 Realm，我已经通过 Cocoapods 成功添加了它。我使用的是 Xcode 6.4，但在同一台机器上安装了 Xcode 7.1 测试版(用于其他项目)。</p>
<p>在尝试构建项目或运行单元测试(在模拟器上)时，我收到一个链接器错误，提示有数十对文件重复。看起来一个提到了 Bitcode，一个没有。</p>
<p>我使用的是 Xcode 6.4 – 为什么它甚至知道 Bitcode？以下是一小部分错误示例:</p>

<p>我见过其他人谈论类似的问题，但不是 Xcode 6.4，也不是简单地运行应用程序，而不是提交到商店。</p>
<p>我还应该指出，将 Realm 添加为静态框架(来自 <code>0.95.3</code> 的 <code>xcode-6</code> 文件夹可以完美运行，因此它与看来我是从 Cocoapods 获得的。</p>
<p>我可以在这里做什么？如果可能的话，我真的宁愿从 Cocoapods 获得它。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>根据您使用的 Xcode 版本，需要不同版本的 Realm 核心库，因此在运行 <code> 时使用 <code>xcode-select</code> 激活相同版本很重要pod install</code> 用于构建项目。由于下载了 Xcode 7 版本的库，您可能已经激活了该版本的 Xcode。运行 <code>sudo xcode-select -s/Applications/Xcode.app/Contents/Developer</code>(假设您安装了 Xcode 6；根据需要进行调整)，删除 <code>Pods</code> 目录，然后重新运行 <code>pod install</code>。</p>
<p>您可以使用 <code>xcrun swiftc -v</code> 检查您激活的 Xcode 版本。</p></p>
