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.

Intro

Prerequisites/Background (Inspired from Functional Programming)

Data - data is inert and does not change by itself.

Example:

immutable struct
immutable data received from an API service, for example JSON, recorded logs etc.

	import SwiftUI
	import Charts

	struct FacilityResponse: Codable {
	let id: String
	let name: String
	let timeZone: String
	let hasConsumption: Bool
	let hasProduction: Bool
	let measurements: Measurements

	import SwiftUI
	import Charts

	struct EnergyReading {
	let timestamp: Date
	let kWh: Double
	}

	struct EnergyBarChartView: View {
	@State private var energyData: [EnergyReading] = {

	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,
