Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

import UIKit

/// A scroll view that allows scrolling using a hardware keyboard like `NSScrollView`.
/// Supports arrow keys, option + arrow keys, command + arrow keys, space bar, page up, page down, home and end.
/// Limitations:
/// - Paging scroll views (isPagingEnabled = true) are not supported yet.
/// - The scroll view must become its own delegate so setting the delegate is not supported yet.

import UIKit

//It basically just gets image from assets, saves its data to disk and return file URL.
class AssetExtractor {

    static func createLocalUrl(forImageNamed name: String) -> URL? {

        let fileManager = FileManager.default
        let cacheDirectory = fileManager.urls(for: .cachesDirectory, in: .userDomainMask)[0]
        let url = cacheDirectory.appendingPathComponent("\(name).png")
