> When serialising a struct using the TCompactProtocol we have discovered a
> run-time error on line
> [https://github.com/apache/thrift/blob/08a6eb6e1f21aa15682e414e124d7ee1a51a39c7/lib/swift/Sources/TCompactProtocol.swift#L474]
> The Swift implementation of TCompactProtocol assumes that the properties of
> autogenerated classes for Thrift Structs will be ordered by field key, but
> the current behaviour of the generator preserves the order from the original
> thrift definitions These are not required to be ordered by field key.
> Either the Swift lib needs to check for out-of-order properties, or the
> generator should order properties. Since the generator is only executed once
> and the Swift lib runs every time a message is serialised, I think it makes
> more sense to make this change in the generator.
> I've made the necessary change, and will soon open a PR.
