I'm receiving a segmentation fault in Xcode 11 when I do an Archive of Generic iOS Device. The file this apparently is occurring in, "InformationMenu", hasn't been touched in months so I have no idea what's causing this.
I've tried making changes to the Optimization Level with no luck. The app builds on devices and simulators which makes this all the more frustrating.
Everything is written in Swift 4, target is iOS 11 and above.
Not sure where to go from here.

I have an Obj-C class extending NSObject. One of its properties is an NS_ENUM; let's call it direction.
Then I have a Swift class with an optional property of this Obj-C class; let's call that message.
The following example code is fine:
switch message?.direction
{
case .Inbound:
...
case .OutBound:
...
case nil:
...
}
However, if I then introduce:
guard let message = self.message else { return }
and remove the ? in the code above, the compiler crashes; see below.
It seems to get confused by case nil:, because the crash disappears if I delete it; it's of course no longer needed.
Just curious, has anyone seen this Swift compiler crash?

The issue happen in Swift3 with XCode10.That maybe be a Swift bug。 Actually，clean and rebuild can solve the issue，but that wast too much time。Any body know a effect way to solve or avoid the issue。Thank you

2. While deserializing SIL vtable for 'WSNotificationOperCell' in module 'myProject'
error: Abort trap: 6
This is a Swift compiler bug. It's possible that you're triggering it by linking modules that were compiled by different versions of the compiler, or some other unsupported behavior, but it probably still shouldn't crash.
However, you say it's a Swift 3 problem. The Swift developers no longer support Swift 3. They are working on Swift 5. If you can reproduce the problem in Swift 5, you can file a bug report at https://bugs.swift.org.
I'm trying to include a hardcoded version string generated by git describe within a CLI I'm writing in Swift.
The idea was to have a shell script that executes git describe and writes that as a global constant into a file called Version.swift, which I can then reference from within my tool.
I don't want to have to think about running this script before every build though or building the project via another shell script. The ideal way would be to keep using swift build and having Swift itself invoke said script when it compiles and evaluates Package.swift.
So I included the following in my package manifest.
import Foundation
let task = Process()
task.launchPath = "./"
task.arguments = ["update_version.sh"]
task.launch()
task.waitUntilExit()
Whilst importing Foundation and initializing the task seems to work just fine, actually launching it crashes and outputs the following stack trace.

What could I do here to get this to work? Does this have to do with the package manifest being executed within a sandbox? And if so, what options do I have to accomplish what I'm trying to do? If in any way possible I'd really love to just run swift build and have the rest just work.
the exception has NOTHING with your approach, the system raised it because your launchPath is NOT a valid launch path :-). You have to be ABSOLUTELY sure about the validity of your launchPath, otherwise, the execution will be terminated with some uncaught exception. For a solution see how to solve it
