That's unfortunate. Assuming you're on macOS, do you mind running
that might reveal some compiler crash reports. If yes I think the best would be to file a bug for these crashes on http://bugs.swift.org . What presumably would be most helpful is a small reproduction of that crash but I realise that can be hard at times...

Project builds fine for earlier compiler releases. The crash gives no stack trace in console. The crash occurs for one framework component within a complex project with multiple frameworks + app with lots of inter-dependency so its hard to know what specifically is causing the issue or produce something to reproduce and file with a bug report. If I turn off optimisation for that one framework the whole project builds.
