Swift：从 iOS 7 编译存档时出现分段错误

【中文标题】Swift：从 iOS 7 编译存档时出现分段错误

【英文标题】：Swift: segmentation fault when compiling for Archive from iOS 7

【问题描述】：

我一直有这个问题，所以我开始用 Swift 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，但如果我设置 iOS 7.1（或 7），我会遇到分段错误。当我转到产品>存档时，当我在模拟器或我的设备中运行项目时，就会发生这种情况，一切都很好。我尝试了 iOS 7 和 8 模拟器，它可以编译。 正如我所说，问题不在于代码，因为即使是新创建的项目，它的行为也是如此。

1.  While type-checking 'ViewController' at /Users/francesco/Documents/XCode Projects/Prova/Prova/ViewController.swift:11:1

Command failed due to signal: Segmentation fault: 11

有人知道这个问题吗？

更新：我可以将 armv7s 和 arm64 定位到 iOS 7，armv7 是导致问题的原因；如果 armv7 针对 iOS 8 而其他针对 iOS 7，则一切正常。在我看来，这不是一个好的解决方案，因为在旧设备上支持旧操作系统更为重要。

【参考方案1】：

我遇到了同样的问题，直到有人告诉我这是证书的问题。转到开发中心并重新生成您的证书和配置文件。之后它应该可以工作了！

【讨论】：

全部设置为自动，所以 Xcode 会发现并（尝试）修复问题，对吧？

不，这无济于事。您还必须更新您的证书（上传新的代码签名请求 (.csr) 文件并重新创建所有配置文件）。

天哪。这对我来说绝对是。我去了首选项>帐户>详细信息，然后单击证书上的刷新按钮。不再有段 11 故障。堆栈跟踪是疯狂的误导——谈论类型检查的错误。我正在移动可能模棱两可的 TypeAlias，各种各样的东西。谢谢@Hannes！

【参考方案2】：

关闭 Xcode 并打开另一个项目，然后加载回这个项目，解决了这个问题。 我猜这是一个错误。

【参考方案3】：

我在 Xcode 6.1 上遇到了同样的问题。构建和运行 Swift 项目没有问题，归档导致错误：

Command failed due to signal: Segmentation fault: 11
1.  While type-checking <my Swift class>

将项目的部署目标从7.0 更改为7.1 解决了问题，现在可以归档应用了。

【参考方案4】：

我遇到了同样的问题，尝试选择的答案（即关闭和重新打开 Xcode 等）以及其他实验都没有帮助。根据堆栈跟踪，以下代码失败：

var cell = self.tableView.cellForRowAtIndexPath(NSIndexPath(forRow: row, inSection: 0)) as UITableViewCell
var cell2 = self.tableView.cellForRowAtIndexPath(NSIndexPath(forRow: row2, inSection: 0)) as UITableViewCell

在随后的代码中，我将 cell 和 cell2 都视为可选项，因此我没有费心解开这些赋值。显然，斯威夫特讨厌它，以至于对我造成了段错误。经过一些实验，我将代码更改为

var cell = self.tableView.cellForRowAtIndexPath(NSIndexPath(forRow: row, inSection: 0)) as UITableViewCell!
var cell2 = self.tableView.cellForRowAtIndexPath(NSIndexPath(forRow: row2, inSection: 0)) as UITableViewCell!

并且 Swift 分段错误停止了。问题出在 Xcode 6.1.1 (6A2008A) 上。

如果您仍然遇到此问题，您应该查看堆栈跟踪提到崩溃发生的位置。它会说一些关于发出代码的信息，并且应该是可定位的。

【参考方案5】：

我遇到了同样的问题——编译在模拟器和设备上都可以正常运行，但在归档期间我会得到seg fault 11。我在这里尝试了其他一些解决方案，但仍然出现错误。

我将原因隔离为使用泛型和 NSCoding 协议的方法。删除协议解决了这个问题。

这导致了段错误：

 func saveToDefaults<T: NSCoding>(objectToSave : T?, key : String)

但将其更改为修复它：

 func saveToDefaults<T>(objectToSave : T?, key : String)
     if let objectToSave = objectToSave as? NSCoding 
          ...

它不像原来的那么健壮，但它可以编译。
