I just tried another Mac, using exactly the project I uploaded, and to begin with it looked like there was no memory leak. However, when I reduced the timer interval from 0.1 to 0.01, I saw the leak. It just develops much slower on this machine, although the app itself is still running at full speed.
The two machine configurations are:
Original machine is an iMac running OSX 10.10.5 and Xcode 6.4, and Xcode is running the project on a simulated iPhone6 with iOS 8.4.
The machine I just tried is a MacBook Pro running OSX 10.10.5 and Xcode 6.3, and Xcode is running the project on a simulated iPhone6 with iOS 8.3. (Currently downloading Xcode 6.4, but that is likely to take a while.)
With a timer interval of 0.01, the MacBook Pro shows about 2 new 32-byte allocations per second, and the iMac shows about 100 per second.
