swift - Use of undeclared type 'BackendlessCollection' -


hi new backendless. please help. getting error use of undeclared type 'backendlesscollection' while using in ios . swift

i have written function retrieveblurbs() in home view controller.i have created 1 more object medicinelist class this

class medicinelist : nsobject {      var objectid : string?     var name : string?      var desc : string?     var created : nsdate?     var updated : nsdate?  }   func retrieveblurbs() {     var backendless = backendless.sharedinstance()     let query = backendlessdataquery()     // use backendless.persistenceservice obtain ref data store class     backendless.persistenceservice.oftable(medicinelist.ofclass()).find(query, response: { ( medicinelist : backendlesscollection!) -> () in         let currentpage = medicinelist.getcurrentpage()         print("loaded \(currentpage.count) medicinelist objects")         print("total restaurants in backendless starage - \(medicinelist.totalobjects)")          medicinelist in currentpage as! [medicinelist]         {             print("medicine name = \(medicinelist.name)")         }         } , error: { ( fault : fault!) -> () in             print("server reported error: \(fault)")         }) }

enter image description herei'm not sure, helpful

i've looked @ api, if using asynchronous method signatures, method "find" query variable has 2 non optional blocks response , error.

i try change method this:

func retrieveblurbs() {     var backendless = backendless.sharedinstance()     let query = backendlessdataquery()     // use backendless.persistenceservice obtain ref data store class     backendless.persistenceservice.oftable(medicinelist.ofclass()).find(query) { medicinelist in         let currentpage = medicinelist.getcurrentpage()         print("loaded \(currentpage.count) medicinelist objects")         print("total restaurants in backendless starage - \(medicinelist.totalobjects)")          medicinelist in currentpage as! [medicinelist]         {             print("medicine name = \(medicinelist.name)")         }      } , { fault in             print("server reported error: \(fault)")         } }

if won't help, maybe have make sdk setup beginning, module or file might missing during first setup

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
