No colision detection with edges when panning node fast - ios

Question

Im freaking out with this collision issue:
panned ball breaks out edgeloop body when panned fast. Anyone had simillar problem?
Here is scene code ilustrating the issue.
(Replacement MyScene in xcode sample - spritekitgame)
#import "SAMyScene.h"
/* Bitmask for the different entities with physics bodies. */
typedef enum : uint32_t {
SAColliderTypeBall = 0x1 << 1
,SAColliderTypeEdge = 0x1 << 3
} SAColliderType;
NSString * const SABallName = #"ballNode";
#interface SAMyScene()
#property (nonatomic, strong) UIPanGestureRecognizer *panGestureRecognizer;
#property (nonatomic, strong) SKShapeNode *ball;
#end
#implementation SAMyScene

self.ball = [self newBallNode];
[self addChild:self.ball];
}
return self;
}
- (SKShapeNode *)newBallNode {

CGMutablePathRef myPath = CGPathCreateMutable();
CGFloat radius = 60.0;
CGPathAddArc(myPath, NULL, 0,0, radius, 0, M_PI*2, YES);
