Question

On build of a project I am getting an Assertion failed pointing at this code. Any ideas why please? I have tried a cleaning, deleting derived data, closing xcode and more. Any help please.

unsigned int
FNVForCString(
    const char* s)
{
assert(s);

unsigned int hash = 2166136261;
int ch;
while (0 != (ch = *s++))
{
    hash *= 16777619;
    hash ^= ch;
}
return hash;
}

Just going to say it is failing on the assert(s); line.

Answer 1

Is the language C? I’ve made that assumption here, though the answer varies very little if this is Objective-C.

The value you pass into the function is NULL

The assert is there to say “If the value s is NULL, fail at this point.
