I have an error "Command failed due to signal: Segmentation fault: 11" when I compile my Swift code with a library Eureka. I am using Xcode Version 7.3 (7D175). My situation is similar to this question.
In the question above, some people were getting the same error with Eureka but it doesn't help me. I have just created a new project and done "pod install". Then I added "AgeRow.swift". So, this project is minimum and clean.
Here is a small sample that causes the segmentation fault error.
Please make sure this sample depends on Eureka 1.5.0.
I am writing my custom row named AgeInlineRow. When I comment out the AgeInlineRow class, the sample can be compiled. That is, other code seems not to be the cause of the error.
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
}
}
When I remove InlineRowType protocol and modify code to compile, this project can be compiled. So, I guess the cause is InlineRowType protocol and this is the limits of my debug abilities. I have no idea how can I bypass the issue. I have copied Eureka's PickerInlineRow code and modified. Of course PickerInlineRow doesn't cause segmentation fault.
I would be grateful if you could specify the reasons.
Here is the error message below.

P.S. I would like to make a custom inline row that has UIPickerView with two components.
