updateMotionControl Xcode issue, page 260 (update: user error)

From page 260, Xcode insists on adding ‘self’ in 2 places on this line:

self.ballNode.physicsBody!.velocity += self.motionForce

‘reference to property ballNode in closure requires explicit self to make capture semantics explicit’ is the error message it gives.

With the ‘selfs’ in place, the accelerometer input is not working.

Not a big deal, loving the book, any feedback would be appreciated.

update: my error, the line of code needed to be outside of a brace to be OK.
