I've gone to an older project that needs to have the SDK updated for the scanner that it uses. 我去了一个较旧的项目，需要为其使用的扫描仪更新SDK。 The new SDK is 64bit ready and so the app needs updating. 新的SDK已准备好64位，因此应用程序需要更新。 The SDK is installed by dragging and dropping into the project but after that I get the following error when building: SDK是通过拖放到项目中安装的，但之后我在构建时遇到以下错误：

Note: I was getting an error referring to arm64 but this one currently says armv7 because I fiddled. 注意：我收到一个错误，指的是arm64但是这个当前说的是armv7因为我摆弄了。
