ios - Using Object Initializers in Swift to replace AllocWithZone -

-

i updated xcode xcode 7 beta 4 xcode 7 beta 5 , began have error wasn't present before. being: "allocwithzone unavailable in swift: use object initializers instead."

here code error found: 

public func copywithzone(zone: nszone) -> anyobject {     let copy = self.dynamictype.allocwithzone(zone) chartdataset     copy.colors = colors     copy.label = self.label     return copy }

what substitute in place of ".allocwithzone" utilizes object initializer instead of obj c component?

i used this, , ios charts library works me:

let copy=self.dynamictype.initialize() as! chartdataentry

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
