更新到Swift 4.2之后的Xcode构建错误-体系结构arm64的未定义符号 [英] Xcode Build Error after updating to Swift 4.2 - Undefined symbols for architecture arm64
问题描述
我正在尝试构建自去年6月以来从未涉及过的Xcode iOS项目.我知道软件包进行了一些更新，而Swift 4.2进行了一些更新，但是出现了很多错误.
首先，我遇到了类似 我试图查看SupportViewController.swift以查看是否有可能导致它的东西，但没有找到任何东西.我也不知道如何使用-v查看调用.是什么原因造成的?该项目之前运行良好，我认为更新可能会弄乱一些事情. 以下是控制器的要点: https://gist.github.com/arkwl/8bcf492cef2e8408852d1be98172b7b7 我还尝试过将链接器标志添加到pods项目中，如下所述: https://stackoverflow.com/a/26903572 /4672331 是的，我确实尝试过重建. 嗯.这里有几种可能，但最有可能的似乎是RestKit框架不是在您的代码之前构建的.在使用它的任何源代码中，您当然都应该有一个 通常来说，除非框架doco表示要这样做，否则您无需修改任何链接器标志.在框架搜索路径中没有正确的框架路径是此类问题的更常见来源. 此外，您还提到了加载框架图像的早期问题.通常在应用程序启动期间实际尝试加载框架时会出现此错误.最常见的原因是已将框架链接进去进行编译，但没有将其复制到应用程序捆绑包中进行部署. 因此，我建议您查看RestKit框架的构建位置以及构建方式(Carthage或CocoaPods或其他东西)，在框架中指定的路径搜索路径设置，以及如何将框架添加到应用程序中. /p> I am trying to build an Xcode iOS project I haven't touched since last June. I know there have been some updates with packages and something with Swift 4.2 but I got a multitude of errors. Firstly I got a library not loaded error similar to this but for RestKit. I added it to my pods file and included it into I tried to look at SupportViewController.swift to see if there's anything that could be causing it but haven't found anything. Also I don't know how to use -v to see invocations. What could be causing this? The project was working fine before, I think the update might have messed up a few things. Here's the gist for the controller: https://gist.github.com/arkwl/8bcf492cef2e8408852d1be98172b7b7 I have also tried adding the Linker Flags to the pods project, mentioned here: https://stackoverflow.com/a/26903572/4672331 Yes, I did try rebuilding. Hmm. There's a few possibilities here but the most likely seems to be that the RestKit framework is not being built before your code. You should certainly have (as suggested in the comments) a Generally speaking, unless a frameworks doco says to do so, you don't need to modify any linker flags. Not having the correct paths to the framework in the framework search paths is a more common source of this sort of issue. Also you mention an earlier problem loading the framework image. This normally appears when actually trying to load the framework during your app's startup. The most common cause being that the framework has been linked in for compilation, but not copied into the application bundle for deployment. So I'd suggest looking at where the RestKit framework is being built and how (Carthage or CocoaPods or something else), the paths specified in your framework search path settings and then how the framework is being added to the app. 这篇关于更新到Swift 4.2之后的Xcode构建错误-体系结构arm64的未定义符号的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！import RestKit语句(如注释中所建议).但是对我来说，这个错误是说它找不到框架.因此，我将回顾构建RestKit的日志部分，并确保这样做没有错误.

import RestKit statement in any source code that uses it. But to me this error is saying it cannot find the framework. So I'd look back at the parts of the logs that built RestKit and make sure there are no errors doing that.
