由于信号导致命令失败：分段错误：Eureka 1.5.0 发生 11
Command failed due to signal: Segmentation fault: 11 occurred with Eureka 1.5.0
当我使用库 Eureka 编译 Swift 代码时出现错误 "Command failed due to signal: Segmentation fault: 11"。我正在使用 Xcode 版本 7.3 (7D175)。我的情况类似于this问题。
在上面的问题中，有些人在使用 Eureka 时遇到了同样的错误，但这对我没有帮助。我刚刚创建了一个新项目并完成了 "pod install"。然后我添加了"AgeRow.swift"。所以，这个项目是最小的和干净的。
Here是小样本导致segmentation fault错误。
请确保此示例依赖于 Eureka 1.5.0。
我正在编写名为 AgeInlineRow 的自定义行。当我注释掉 AgeInlineRow class 时，示例可以编译。也就是说，其他代码似乎不是错误的原因。
public final class AgeInlineRow: _AgeInlineRow, RowType, InlineRowType {
required public init(tag: String?) {
super.init(tag: tag)
onExpandInlineRow { cell, row, _ in
let color = cell.detailTextLabel?.textColor
row.onCollapseInlineRow { cell, _, _ in
cell.detailTextLabel?.textColor = color
}
cell.detailTextLabel?.textColor = cell.tintColor
}
}
public override func customDidSelect() {
super.customDidSelect()
if !isDisabled {
toggleInlineRow()
}
}
public func setupInlineRow(inlineRow: InlineRow) {
inlineRow.year_options = self.year_options
inlineRow.month_options = self.month_options
inlineRow.displayValueFor = self.displayValueFor
}
}
当我去掉InlineRowType协议并修改代码编译后，这个项目就可以编译了。所以，我猜原因是 InlineRowType 协议，这是我调试能力的极限。我不知道如何绕过这个问题。我复制了Eureka的PickerInlineRow代码并进行了修改。当然 PickerInlineRow 不会导致分段错误。
如能说明原因，将不胜感激。
