How to get the current selected Xcode and list installed

Current Selected Xcode

`xcode-select`

This is the most common way to get the path to the selected instance:

xcrun xcode-select --print-path

Connecting to a Raspberry Pi through a VPS using a reverse SSH tunnel

SSH (Secure Shell) to a host existing in an internal network through a reverse-tunneled SSH connection to an externally accessible VPS (Virtual Private Server). This setup is described where the internal host is a Raspberry Pi, but can be generalized for any host on the internal network that runs an OpenSSH server.

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 registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

	import Foundation

	enum AppDefault {
	case APIServer, runMode, homeDirectory, reactHost

	var stringValue: String? {
	get {
	return NSUserDefaults.standardUserDefaults().stringForKey(String(self))
	}

	1. Open Terminal
	2. cd to your Xcode project
	3. Execute the following when inside your target project:

	find . -name "*.swift" -print0 \| xargs -0 wc -l

	import PlaygroundSupport
	import Foundation
	import Combine

	// MARK: - Network Controller
	protocol NetworkControllerProtocol: class {
	typealias Headers = [String: Any]

	func get<T>(type: T.Type,
	url: URL,
