Right. The reality, though, is that many of us have fairly large Pascal codebases. In many cases, it would be foolish to attempt to rewrite that Pascal code in Swift, or any other language. What I've presented in the library articles is a way to preserve the value of that code by using it with other languages.
Well, whether it's foolish or not, it depends on many things and considerations. Sometimes we do need to reinvent the wheel, rewrite the whole things, and move on.
Besides, who said I'm going to do that? I'm still learning Swift and I won't master it over night that I would be confidence enough to rewrite my Pascal codes. Even if I do rewrite my precious Pascal codes into Swift, the decision and risk are on me. It's my problem, not yours.
Thank you for your concern anyway. I appreciate it.
