Deprecation

[Ali via Digitalmars-d-learn]

Hello. I am having an issue with the code below. the out put 
after compiling is this :

Deprecation: foreach: loop index implicitly converted from size_t 
to uint

the code is :

auto available = new int[cast(uint) max - min];
                foreach (uint i, ref a; available)
                        a = min + i;

Any help would be highly appreciated.
