Eureka: Command failed due to signal: Segmentation fault: 11 after adding another Pod to my project.

Hey there, after adding another cocoapods dependency to my project. My release builds started to fail with this error:
Command failed due to signal: Segmentation fault: 11

The error log is long, but this is at the bottom of it:

                return self.useFormatterDuringInput ? formatter.editingStringForObjectValue(v as! AnyObject) : String(v)
            }
            return formatter.stringForObjectValue(v as! AnyObject)

• Environment: Eureka 1.7.0, Xcode 7.3.1 and iOS 2.3.

My question is, how can I pinpoint the exact issue here?

Hey @yigitserin !
have you found a workaround for this issue ?

[gigDOTbg]

I have the same issue on macOS 10.12.5, Xcode 7.3.1, Eureka 1.7.0.
From my point of view the cause of this compiler issue is the casting:
self.cell.textInput as? UIView

[gigDOTbg]

The workaround for this issue is to set the SWIFT_OPTIMIZATION_LEVEL for the Release build to "Fast [-O]" instead of "Fast, Whole Module Optimization [-Owholemodule]" (which is the default introduced in CocoaPods 1.2.1).

I have the same issue. how to resolve it?

[felipericieri]

In my case, looks like it was something related to associatedtype. As soon as I commented it, it could compile.

[mats-claassen]

This looks like a compiler issue. Does it still happen with Swift 4?

I am facing same issue with the same environment, can anyone help me out please.

I just wasted an hour fighting a similar issue in my code. It went away when I changed an [unowned self] to a [weak self].
