Swift Command failed due to signal: Segmentation fault: 11 -

-

here code:

func cache<t: cacheable>(type: int, items: array<t>, options: cacheoptions?) {     log(log_http, "caching ... \(items)")      item: cacheable in items {         let key: string? = item.primarykeyvalue()     } }

it's pretty simple, cacheable protocol:

public protocol cacheable: class {     func primarykeyvalue() -> string? }

and compile fails signal issue. if remove :class cacheable, compile go through, when need:

nscache().setobject(item, forkey: "key")

it complains cacheable not conform anyobject protocol, stuck here. help? thanks.
