Authentic and inspiring! 👍

The type of bytes is [UInt8]. Thank you for bringing more details. I have to confess I didn't check the docs before use. My purpose was to satisfy the argument type: parameterSetPointers: UnsafePointer<UnsafePointer<UInt8>>.

Thank you! This information is really helpful! I will migrate my code to 26 and try again.

I solved this by making the State implementing CustomStringConvertible. Seems like "text interpolation" works differently here.
