"UIApplication" undeclared (first use in this function)

So help anyone?

As others have said, UIApplication is part of UIKit, a Cocoa Touch framework for iOS. On the Mac, you have to use AppKit, a Cocoa framework for Mac OS X, which provides NSApplication.

That being said, if you want to open a URL you need to use NSWorkspace:

[[NSWorkspace sharedWorkspace] openURL:[NSURL URLWithString:@"http://google.com"]];

You can't use UIApplication. You need to use NSApplication instead.

try NSApplication
