xcode - Could not cast value of type - Objective C NSManagedObject in Swift -

-

i've found numerous posts error being able resolve adding prefix of project name class in entity viewer e.g projectname.journey suggestion of adding @objc(classname) above class declaration. these solutions don't work me. problem have nsmanagedobject class generated in objective c try access in swift. following error:

unable load class named 'projectname.journey' entity 'journey'.  class not found, using default nsmanagedobject instead. not cast value of type 'nsmanagedobject_journey_' (0x1700541f0) 'journey' (0x100096f38).

my class: h:

#import <foundation/foundation.h> #import <coredata/coredata.h>   @interface journey : nsmanagedobject  @property (nonatomic, retain) nsstring * travelmode; @property (nonatomic, retain) nsdate * starttime; @property (nonatomic, retain) nsdate * endtime; @property (nonatomic, retain) nsnumber * averagespeed; @property (nonatomic, retain) nsnumber * distance;  @end

m:

#import "journey.h"  @implementation journey  @dynamic travelmode; @dynamic starttime; @dynamic endtime; @dynamic averagespeed; @dynamic distance;  @end

my code trying access code in swift:

for res in results {   var move: journey = res as! journey; //error thrown here   var morningstamp = midnightdate!.timeintervalsince1970;   var eveningstamp = morningstamp + 86400;   if(move.starttime.timeintervalsince1970 > morningstamp) {      if(move.endtime.timeintervalsince1970 < eveningstamp)     {       filtered.addobject(move);     }    } }

bridge header file:

// //  use file import target's public headers expose swift. //  #import "travelrecordmanager.h" #import "journey.h"

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

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...

mercurial graft feature, can it copy? -

-
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.
