similar crash issue on ios8 gklocalplayerinternal unrecognized selector

i tried test using sknode , gkplayer

sknode* node = [sknode node]; gkplayer* player = [gklocalplayer localplayer]; [node isequal:player];

it cause next exception same above result, means scheme compare sknode [gkplayer postchangenotification]....it's weird.

-[gklocalplayerinternal name]: unrecognized selector sent instance 0x1b6e3f80

if can replicate crash comparing sknode gklocalplayer seem this bug in spritekit performing equality check on object should not result in crash.

if have stamina it, subclass sknode's in app , implement isequal , hash methods yourself. should avoid faulty name comparing check on objects not implement selector.

i recommend study bug apple.

this question seems indicate apple did indeed update sknode equality , hashing methods in ios8, bug caused change.
