> Unfortunately, programs that only compile with a no-asserts toolchain aren’t quite perfectly valid. At the very least it means you’re exercising some compiler code path that’s not covered by tests, so it could regress in a future release. We’ve also seen bugs where an input program that trips an assertion then silently miscompiles without asserts. So does that mean that the Xcode toolchain has these assertions enabled, but generates code in a more correct way? Or does the xcode toolchain disable these assertions, potentially allowing through code that can silently miscompile? If thats the case should people be concerned about using these features in production systems? --- _[View the full topic](https://forums.swift.org/t/can-we-get-consistent-assertion-behavior-in-the-latest-release-swift-compiler-across-host-platforms/80545)._
