12,117 PointsCrystalBall app error with randomization
Hi there!
An error with my following line of code appeared in my CrystalBall.m file after I launched in on my iPhone:
int random = arc4random_uniform(self.predictions.count);
It says "Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'u_int32_t' (aka 'unsigned int'). Anyone have any idea how to fix this issue? Thanks in advance!

42,016 Pointscast your count to a 32 bit unsinged int. arc4random expects a 32 bit integer. if you are running on a 64 bit system the count variable is 64 bit integer, which makes the compiler complain. you can safely cast this to resolve the compiler warning
int random = arc4random_uniform((uint32_t)self.predictions.count);
