使用Swift的没有Storyboard或Xib文件的OSX应用程序

如果您不想拥有@NSApplicationMain属性，请执行以下操作：

1. 有一个文件main.swift
2. 添加以下顶级代码：

        import Cocoa    let delegate = AppDelegate() //alloc main app's delegate class    NSApplication.sharedApplication().delegate = delegate //set as app's delegate    // Old versions:    // NSApplicationMain(C_ARGC, C_ARGV)    NSApplicationMain(Process.argc, Process.unsafeArgv);  //start of run loop

其余的应该在您的应用程序委托中。例如：

    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)        }    }

然后你有一个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        }    }
