• Swift Algorithm Club: https://github.com/raywenderlich/swift-algorithm-club)
2 - A foundational library to many server-side swift initiatives, swift-nio exposes high level building blocks for interacting with non-blocking IO, such as files, streams, and datagrams.
• swift-nio: https://github.com/apple/swift-nio)
3 - Built on top of swift-nio, swift-metrics is a package primarily intended for web analytics that makes it easy to collect data from your server application in a privacy conscious way.

Compiler Error
By using extended delimiters for string literals, all special characters including the backslash will be represented as normal characters.
Not limited to optionals, any type can conform to ExpressibleByNilLiteral to have a special initializer called if nil is used along with that type.
Like integer literals, floating point literals can be expressed in binary, octal, decimal, or hexadecimal forms.
Although Dictionaries prohibit it, ExpressibleByDictionaryLiteral allows for multiple entries with the same key.

Compiler Error
Introduced in 1987, the Macintosh SE was a Special Edition of the 128k Mac that was the first Mac to offer a color display as an option, although limited to 8 bits.
Introduced 2 years later as a processor update of its predecessor, the Macintosh SE/30 was unofficially expandable to a whopping 128 MB of RAM, an amount that was greater than many future models, and its board and front panel were available as official upgrades for the original Macintosh SE.
A surprise to many, the SE naming made a comeback in 2016 as the iPhone SE, a Special Edition of iPhone 6S that used the iPhone 5S case, and would mark a new tier of low-cost iPhones with up-to-date components.
Available today, the Apple Watch SE follows in the footsteps of the iPhone SE, but rather than use the internals of the flagship Series 6, it is instead closer to a limited variant of the Series 5, with an S5 package on a chip, but without an always-on display and electrocardiogram sensor.

Streaming game services may offer a catalog app on the App Store to help users sign up for the service and find the games on the App Store, provided that the app adheres to all guidelines, including offering users the option to pay for a subscription with in-app purchase and use Sign in with Apple.
Apps in the Kids category must not include links out of the app, purchasing opportunities, or other distractions to kids unless guarded behind a parental gate.
Screenshots should not include text and image overlays other than to illustrate the app in use, and they must not use any Apple devices or products for marketing purposes.
If your app displays Activity rings, they should not visualize Move, Exercise, or Stand data in a way that resembles the Activity control.

Review the following code — what might the developer have overlooked?
class DateCell: UITableViewCell {
private static let dateFormatter: DateFormatter = {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "YYYY-MM-dd"
return dateFormatter
}()
var date: Date? {
didSet {
switch date {
case .some(let date):
textLabel?.text = Self.dateFormatter.string(from: date)
case .none:
textLabel?.text = "N/A"
}
}
}
}
### Compiler Error
The theme for this week is Emacs key bindings in Cocoa:
Although the same can be done using modifier and arrow keys, the text cursor can be quickly moved to the beginning and to the end of a document by using ⌃A to go to the beginning, and ⌃Z to go to the end.
You may know of the ⌘⌫ command to delete the entire line to the left of the text cursor, but ⌃K can be used to delete the line to the right of the text cursor.
Available as an alternate clipboard, ⌃K and ⌃Y represent the kill and yank operations that let you cut and copy text without overriding your main clipboard. The clipboard they use is called the kill ring.
⌃T is a useful command for transposing two letters that were typed out of order, by flipping the characters on each side of the text cursor.
Can you spot which one is the Compiler Error?

Invert and reduce the following if statement without introducing any new variables or statements:
let boolA, boolB, boolC: Bool
let intA, intB, intC: Int
// TODO: Invert this statement so we don't need an else block:
if boolA && !boolB || (boolC && intA == intB || intC > intA) {
// Do Nothing
} else {
print("The condition above was not met. Do the thing!")

This week's Compiler Error has a theme: Obscure Apple Products:
1 - A key player in pioneering the digital publishing space, Apple made several printer models in 80s and 90s such as the popular ImageWriter and LaserWriter, but they also made the Apple 410 Color Plotter, a printer that used a stylus along with a selection of inks to literally draw shapes and text on the page.
2 - Available for sale for just a couple years, iPod Socks were a series of pouches for iPods woven like socks, and came as a package with six colors: grey, orange, pink, blue, green, and purple. For a limited time, they were also available in human sizes at the Apple Company Store in Cupertino.
3 - Known now as a feature that allows videos to be quickly taken by pressing and holding the shutter button on modern iPhones, the Apple QuickTake was a line of video cameras that could be used tethered to a Mac, or on the go thanks to AA batteries.
4 - Released in 2006, the iPod Radio Remote was an attachment for then-new iPods that was shaped like a then-unreleased clip-style iPod Shuffle, that allowed compatible iPod users to use their iPods as an FM Radio tuner.
