Comment by Kyle Hickinson (JIRA)
Just an FYI: This seems to be fixed in Xcode 9 beta 1 🙂
Ah, I believe the Xcode beta has assertions turned off. So it's possible you're just squeaking by, or even that the compiler is emitting nonsense, which means it's still worth it for us to look into this!
I can't reproduce this on the latest swift-4.0-branch
, swift-4.0-branch-06-02-2017
branch, or master
(with all assertions turned on). I feel pretty confident in saying this probably got fixed soon after that toolchain was put out.
kylehickinson (JIRA User) Have you been able to reproduce this since?

Just tried this on Xcode 8.3.2 using switch swift Jun 6th Swift 4 Toolchain and still got the assertion crash (using the uploaded CodableCompilerCrash.zip project)

Just noticed though that there's a Jun 7th snapshot to download so I will download that a bit later (currently tethering commuting from work) and test it out.

Unfortunately I'm still getting the assertion with June 7th release, here is the build log (I tried using xcodebuild
this time)

I am experiencing the same bug as this under Linux inside a Docker container. Using the above code, but modified to exist in a swift package, I have reproduced this bug using swift-4.0-DEVELOPMENT-SNAPSHOT-2017-07-11.
Requirements: A Mac, with docker installed (see https://www.docker.com/docker-mac)
To reproduce:
1. Grab the attached zip file: testpkg.zip
I don't have time to look at the moment, but I believe the manifestation of this bug will go away with one of the changes in PR-10723. It's orthogonal to the issue that the PR is trying to solve, but the additional eager validation in `CodingKeys` should prevent this assertion from triggering.
@itaiferber: No worries—I will keep an eye on that PR, then. Once merged and available in a snapshot, I'll re-test the larger, more complicated package where I first got hit by this bug.
For the sake of completion, I managed to reproduce this on my Mac using the same snapshot. Previous (successful) runs were using Xcode 9b3, which is strange.
I just ran this command in the testpkg folder:
Yeah, this would be present regardless of OS version since it's happening in compiler validation of the CodingKeys
enum. Thanks for replicating the crash, and hopefully I can get to resolving this soon.
kylehickinson (JIRA User) @liscio Apologies that this hasn't been updated in a while. Has this reproduced on a recent build of Swift/Xcode beta? Some work was done on type validation in PR-11151 that might be relevant to this; I also just tried to reproduce this in Xcode with a recent toolchain and this isn't reproducing for me.

The crash is an assertion coming from (isError) swift::DerivedConformance::deriveCodingKey(swift::TypeChecker&, swift::Decl*, swift::NominalTypeDecl*, swift::ValueDecl*)
It stems from the issue where you define the enum "CodingKeys" yourself — instead of allowing the compiler to generate it — within your Codable object. The object compiles fine, but referencing it from a different file causes a Type not yet validated assertion.
I've attached a sample project and crash stacktrace, and sorry if this is already known and part of https://github.com/apple/swift/pull/8125
