(while using size classes, autolayout..) still same.. it's xcode bug issue.. not autolayout incompatibility problem. any hints? p.s. compiling project run great, , ui elements show intended. don't have xcode7 installed anymore.. suggestions? i can not reproduce crashe, fix messed ui setting following under editor menu -> canvas :
