Xcode 4.1 and lion In my new series of post I decided to write something about xcode 4.1 and lion os that i use in next post. Xcode 4.1 can use in snow leopard also but you should download deferent version For snow leopard .From Xcode 4 you see great change especially in interface of program. You can add library to program in 4 device orientations (portrait upside-down landscape left and right) without add any more code. With new interface you can use deferent editor without leave of xcode .New editor help you to have easier programming. You can switch between editors with click on view and editor in toolbar.I don’t want explain more...
