iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func register(_ cellClass: AnyClass?, forCellReuseIdentifier identifier: String)
public func register(_ nib: UINib?, forCellReuseIdentifier identifier: String)

		kCFNetworkProxiesHTTPEnable as AnyHashable: true,
		kCFNetworkProxiesHTTPPort as AnyHashable: [Place-proxy's-port-number-here],
		kCFNetworkProxiesHTTPProxy as AnyHashable: "Place-your-proxy-address-here"
]

sessionConfiguration.connectionProxyDictionary = proxyConfiguration

A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,
