Showing All Issues Command failed due to signal: Abort trap: 6

This indicates that the Swift compiler has crashed. This is most definitely a bug in the compiler; it shouldn’t crash regardless of what input you feed it. You should file a bug about this, including as much information as you can. Ideally that would include a minimal test project that reproduces the issue.

Please post your bug number, just for the record.

In terms of workarounds, this failure is deep enough in the compiler that it’s not obvious how to map that to your source code. If this problem didn’t occur in Xcode 9.2, then a simple workaround would be to roll back to that. The alternative is to start pulling apart your code looking for the code that triggers this, and that can be a long and hard process.

Hi,

I've got the same issue. However, I noticed this only happens when I'm using the production build. When I use a scheme that uses the debug build, the crash doesn't happen.

But one thing, if we roll back to 9.2m we won't be able to submit to Appstore because of the iOS 12. Is there something we can about this?

Just in case, this is the error I receive:

```

PHI node operands are not the same type as the result!

I'm going to create another thread if needed. Thanks 🙂
