OSX application without storyboard or xib files using Swift

Question

Unfortunately, I haven\'t found anything useful on the Internet - I wanted to know, what code I actually have to type for initializing an application without using storyboar

Answer 1

In Swift 4 it has changed slightly yet again,

The main file must have

import Cocoa

let delegate = AppDelegate()
NSApplication.shared.delegate = delegate

NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv)

The AppDelegate must be

import Cocoa


class AppDelegate: NSObject, NSApplicationDelegate {
    var newWindow: NSWindow?
    var controller: ViewController?

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        newWindow = NSWindow(contentRect: NSMakeRect(10, 10, 300, 300), styleMask: .resizable, backing: .buffered, defer: false)

        controller = ViewController()
        let content = newWindow!.contentView! as NSView
        let view = controller!.view
        content.addSubview(view)

        newWindow!.makeKeyAndOrderFront(nil)
    }
}

The view controller is the same
