swift - IOS Memory Leak From AVFAudio - AVAudioSession -


i try create simple project. in project there images , names , when user push on image, image name played mp3 source file , pass next image. when pass next image, memory usage increasing 300mb fro each next item. when check memory leaks occur helping instruments,i saw of memory leak caused avfaudio library - avaudiosession.

enter image description here

maybe approach wrong play sound. here code play sound:

var sound: avaudioplayer!   func playsound(name: string) {          let path = bundle.main.path(forresource: name, oftype: "mp3")         let soundurl = url(fileurlwithpath: path!)         {             try sound = avaudioplayer(contentsof: soundurl)         } catch let err nserror {             print(err.debugdescription)         }     }   @ibaction func btnclick(_ sender: uibutton) {         playsound(name: "table")         sound.play()      }

is "playing sound" way wrong? why memory leak happen? how solve problem. thank you

i tested on device , memory usage on device around 30-40mb. problem related testing on simulator. don't know why simulator not release avaudiosessions , increase memory usage.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
