OSX application without storyboard or xib files using Swift
if you don't want to have the @NSApplicationMain attribute, do:
-
have a file main.swift
-
add following top-level code:
import Cocoa let delegate = AppDelegate() //alloc main app's delegate class NSApplication.shared.delegate = delegate //set as app's delegate NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv) //start of run loop // Old versions: // NSApplicationMain(C_ARGC, C_ARGV) // NSApplicationMain(Process.argc, Process.unsafeArgv);
the rest should be inside your app delegate. e.g.:
import Cocoa
class AppDelegate: NSObject, NSApplicationDelegate {
var newWindow: NSWindow?
var controller: ViewController?
func applicationDidFinishLaunching(aNotification: NSNotification) {
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)
}
}
then you have a viewController
import Cocoa
class ViewController : NSViewController {
override func loadView() {
let view = NSView(frame: NSMakeRect(0,0,100,100))
view.wantsLayer = true
view.layer?.borderWidth = 2
view.layer?.borderColor = NSColor.red.cgColor
self.view = view
}
}
The top level code sample above no longer works in recent versions of Xcode. Instead use this:
import Cocoa
let delegate = AppDelegate() //alloc main app's delegate class
NSApplication.shared().delegate = delegate //set as app's delegate
let ret = NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv)
