Segmentation Error 11 when code coverage is enabled in Swift

While I run unit tests with XCTest in Swift, they work fine when code coverage is disabled. However, as soon as I try to enable code coverage, I have a failed build / test with 4 classes, resulting in the following error message: Command failed due to signal: Segmentation error: 11 .

Here's what worked for me (since all other suggestions didn't work in my case). I was getting a segmentation error 11 in a specific Swift class when trying to run unit tests with code inclusion enabled. It turns out that we had a ternary expression on a class property like this:

let cellBorder : CGFloat = MyHelperClass.isIPad() ? 10.0 : 6.0

To do this, lazy var fixed the problem:

lazy var cellBorder : CGFloat = MyHelperClass.isIPad() ? 10.0 : 6.0

To be clear, the code compiled and worked perfectly until we tried to enable code coverage . I also found this Open Radar and this post of the guy who outlined the solution. This seems to be Apple's mistake.

Without code, build settings, etc. It's hard to say for sure, but you need to verify that you use the import flag @testablein your unit test classes.

, MyApp unit test, @testable import MyApp.
