The reason was that I had used the same class wide variable in two different classes. Not sure why this is a problem, as they are not in my thinking global to the application, but just global to the class. The classes did not import to each other. Perhaps someone on here can provide a valid reason.

Here is some code to make it clearer.

ViewController1.m

@implementation ViewController1

int sliderSpeed = 500;

ViewController2.m

@implementation ViewController2

int sliderSpeed = 500;
