What does this symbol mean in relation to D?

It can be used in two ways:
1) When used as a unary operator, it means bitwise complement:
assert(~0xaa55aa55 == 0x55aa55aa);
2) When used as a binary operator, it means concatenation:
assert("hello" ~ " world" == "hello world");
auto arr = [ 1, 2 ];
assert(arr ~ 3 == [ 1, 2, 3 ]);
When used with assignment, it means appending:
auto arr = [ 1, 2 ];
arr ~= 3;
assert(arr == [ 1, 2, 3 ]);
It can also be used in the special function name ~this(), which is the
destructor of a struct or a class. (Related functions: 'static ~this()'
and 'shared static ~this()')
