ipad - IOS Photos - Requesting Image for Asset with Swift -

i have updated post on 10 april 2015 new info ...

i have app copying contents of cloud photo album local album on ios device. using following code :

func fetchfullsizeimageforasset(asset:phasset)  -> (uiimage)? {                                                                    // image asset ( nil )      var myimage:uiimage?      let requestoptions = phimagerequestoptions()     requestoptions.synchronous = true     requestoptions.networkaccessallowed = true     requestoptions.deliverymode = .highqualityformat      let screensize: cgsize = uiscreen.mainscreen().bounds.size     let targetsize = cgsizemake(screensize.width, screensize.height)      let imagemanager = phimagemanager()     imagemanager.requestimageforasset(asset phasset, targetsize: targetsize,                                             // targetsize: phimagemanagermaximumsize, gives null image !         contentmode: .aspectfit, options: requestoptions, resulthandler: {             (result, info) -> void in             myimage = result     })     return myimage } 

my idea myimage above code, , copy new local album.

this gives me low quality image (256 x 256) of time, high quality image (640 x 640). have looked @ cloud album images in new photos app on 10.10.3, , high quality (640 x 640)

when use photos @ shared album on ipad, images become high quality when click on them - expected behaviour.

what baffling me these manually clicked images import in high quality when rerun app !

is bug in photokit on ios8 or missing ?
