A stripped down version of your code works as expected here.
- (IBAction) test:(id) sender
{
//set coordinates to x,y -> 0,0 to start
float x = 0;
float y = 0;
while (YES) {
NSLog(@"x = %f, y = %f", x, y);
x = x+100;
//if coordinates are too wide, start new row - if x>300, reset x to 0
and add 100 to y
if(x > 300){
x = 0;
y = y+100;
}
}
}
I have in the past run into spooky code generation bugs.

I wonder if you've run into one too. Does it misbehave in both Debug and
Release builds?
Also, are you sure x is getting past 300?
