Learn Go in ~5mins

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

git init

or

	import SwiftUI

	struct TimeCycleScreen: View {
	@State private var selectedHour: Int = 7
	@State private var selectedMinute: Int = 30
	@State private var isAM: Bool = true
	@State private var timeOfDay: TimeOfDay = .morning

	@State private var celestialProgress: CGFloat = 0.3
	@State private var sliderValue: Double = 7.5

	import AppKit
	import SwiftUI

	class PromptWindowController: NSWindowController, NSWindowDelegate {

	// Essential properties
	private var promptWindowContext: PromptWindowContext
	private let finderContext: FinderContext

	init() {

	@available (iOS 14.0, *)
	public struct MenuPicker<T, V: View>: View {

	@Binding var selected: Int
	var array: [T]
	var title: String?
	let mapping: (T) -> V

	public init(selected: Binding<Int>, array: [T], title: String? = nil,
	mapping: @escaping (T) -> V) {

	import SwiftUI

	struct ContentView: View {
	@ObservedObject var browser = { () -> DocumentBrowserObject in
	let dbo = DocumentBrowserObject (
	forOpeningFilesWithContentTypes: [
	"public.png",
	"public.jpeg"
	]
	)

	import UIKit

	class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

	@IBOutlet weak var tableView: UITableView!

	override func viewDidLoad() {
	super.viewDidLoad()
	NSLayoutConstraint.activate([
	tableView.topAnchor.constraint(equalTo: view.topAnchor),

	// swift 3
	import UIKit
	import AVFoundation

	class VideoPreviewView: UIView {

	private var videoOutput: AVCaptureMovieFileOutput?
	private var captureSession: AVCaptureSession?
	private var previewLayer: AVCaptureVideoPreviewLayer?

	import android.view.animation.Interpolator;

	import static java.lang.Math.*;

	public class BetterBounceInterpolator implements Interpolator {
	private int mBounces;
	private double mEnergy;

	/** Have more control over how to bounce your values.

	# The trick is to link the DeviceSupport folder from the beta to the stable version.
	# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

	# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
	sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

	# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

	# (A similar approach works for older versions too, just change the version number after DeviceSupport)
