Sprite Kit game laggy in simulator with Xcode 7 / Swift 2 -


after upgrading xcode 7 swift 2, sprite kit project laggy on simulator.

it 60 fps, , maxes out @ 15 fps. (if remove textures, goes 60, adding single screen-sized texture drops way down 15 again.)

i've tried running in release mode debug, , makes no difference.

it's still smooth on device.

has else had issue? fixes? makes hard test.

the simulator have lag due fact computer emulating device (so yes have had issue). not problem app (unless changed massive in app during upgrade). cannot speak why frame rate dropped on sim upgrade (probably not optimized yet, plus more features in ios 9 slowing down sim), long on device, should good.

if elaborate on setup (what device(s) have, , computer hardware), , releasing to, can provide more accurate information.

another thing may restarting computer, seems when xcode gets funny.
