Using Swift libraries in Python

So... this is obviously totally, 100%, like for. real. not. supported. by. Apple. …yet?

But still... I thought it was pretty badass. And, seeing how there's already a Swift buildpack for Heroku you could move some slow code into Swift can call it as a library function. But, you know, not in production or anything. That would be silly, right?

Now, having said that, the actual Python/Swift interop may have bugs. I'll leave that as an exercise to the reader.

How to get Python code calling Swift functions:

#!/usr/bin/env python
import ast
from os.path import isfile
from hashlib import md5
from random import randint, choice
from glob import glob
import re

# scratch area

If you've ever wondered what it's be like to "go indie" here is a script with some assumptions that might help you project your income.

Assumptions:

• You will make a new app every month
• Apps have a useful life of 3 years (after that they stop earning money)
• Apps will earn $250 in their launch month
• Apps will earn $100/mo at first (starting month 2), but that revenue will slowly decline (~50% each year)
• As you make more apps your brand/mailing list will start to pay dividends (after 4 apps you'll see the numbers above double, after 8 they'll 3x, and so on)

So how would that work out?
