How to Make a Simple Program With Xcode

Snow Leopard and Later

1. 
   Beginning with Snow Leopard, Apple has deprecated the use of Applescript Studio, but fear not, in spite of a bit of extra typing, things are actually better without it. Go ahead and grab Xcode 3.2.5 or later. You can get 4.0 in the Mac App Store for free.
2. 
   File>New Project
3. 
   Click Applescript Application
4. 
   Name your project, this example is named "Talking Example"
5. 
   Your project should appear
6. 
   Double click "Talking_ExampleAppDelegate.applescript"
7. 
   There are already some items filled in for you. After the property declaration, insert a new handler:

   • on clickedme_(sender)
   • say "hello"
   • end clickedme_
8. 
   Type Cmd+B to build
9. 
   Now double-click MainMenu.xib
10. 
    Interface builder should open. Close any xib windows it brings up from previous projects you may have worked on.
11. 
    A blank window should appear and you can drag a button onto it from the Library.
12. 
    Double click the button and make it "Hello"
13. 
    CTRL-drag from the Hello button to the blue cube called "Talking Example AppDelegate" and let go. You can now pick the clicked-me event handler to link to the "Hello" button you just made.
14. 
    Now click file > save. You many now quit interface builder.
15. 
    In Xcode, press build and go at the top. Your application should run smoothly.
