when the simulator is iPhone 4 inch with 64bit, the Xcode shows this error: implicit conversion loses integer precision

when the simulator is iPhone 4 inch with 64bit, the Xcode shows this error: implicit conversion loses integer precision : "NSUinteger"(aka ‘unsigned long’.),,,

it works with 32 bit ios system.

So is it there solution for generate random number within both 32 bit and 64 bit system ?

if you post your code I could give you a more definitive answer of whats going on

its most likely just a warning, not an error. if you want to get rid of it try casting that integer to a 32 bit integer

(uint32_t)yourVariable

the arc4random_uniform function takes a 32 bit integer and returns a 32 bit integer. if you are on a 64 bit system you are probably passing it a 64 bit integer. try casting the argument to a 32 bit integer as shown above.

-(NSString *) randomQuote{
    int random = arc4random_uniform( (uint32_t)self.quotes.count );
    return [self.quotes objectAtIndex:random];

}

I did as you suggested . it works like a charm !

Thank you ! @Stone Preston
