Swift:从iOS 7编译存档时出现分段错误 [英] Swift: segmentation fault when compiling for Archive from iOS 7

问题描述

我一直都遇到这个问题，因此我开始在Swift中为iPhone和iPad创建一个新的单视图应用程序. 当目标是iOS 8.1时，一切正常，但是如果我设置iOS 7.1(或7)，则会出现细分错误.当我转到产品">存档"时，在模拟器或设备上运行项目时，一切都会正常.我尝试使用iOS 7和8模拟器进行编译. 就像我说的那样，问题不在代码中，因为即使是新创建的项目，它的行为也是如此.

I've always had this issue so I started creating a new single-view application, in Swift, for both iPhone and iPad. When the target is iOS 8.1 everything works fine, but if I set iOS 7.1 (or 7), i get a Segmentation fault. This happens when i go to Product > Archive, when i Run the project in the simulator or my device, everything is fine. I tried with both iOS 7 and 8 simulators and it compiles. As I said, the problem is not in the code since it behaves this way even with a newly created project.

有人对此问题有任何想法吗?

Does anybody have any idea about this issue?

更新:我可以将armv7s和arm64定位到iOS 7，而导致问题的原因是armv7；如果armv7定位于iOS 8，而其他定位于iOS 7，则一切正常.我认为这不是一个好的解决方案，因为在较旧的设备上支持较旧的操作系统更为重要.

UPDATE: I can target armv7s and arm64 to iOS 7, armv7 is what causes the issue; if armv7 is targeted to iOS 8 and others to iOS 7, everything works. That's not a good solution since it's more important to support older OSs on older devices, in my opinion.

推荐答案

关闭Xcode并打开另一个项目，然后重新加载该项目，解决了该问题. 我猜这是一个错误.

Closing Xcode and opening another project, then loading back this one, solved the issue. It was a bug, I guess.
