17.6: Accessing Bitcoind with Swift

ℹ️ NOTE: This is a draft in progress, so that I can get some feedback from early reviewers. It is not yet ready for learning.

This section explains how to interact with bitcoind using the Swift programming language.

Setting Up Swift (Mac)

1. Call up the App Store and Select Xcode

Still on Mojave? [may be safer methodology too]
