Original GitHub issue: https://github.com/OAuthSwift/OAuthSwift/issues/146

Beginner coder here, not sure what I've done wrong but Xcode is shouting at me from this line:

oauthswift.authorizeWithCallbackURL( NSURL(string: "http://google.com"), scope: "basic", state:"INSTAGRAM", success: {
credential, response, parameters in
println(credential.oauth_token)
}, failure: failureHandler)

Error is as title states, "unresolved identifier". Obviously because failureHandler was never declared but declaring shoots out even more errors. Thanks for any advice in advance.

"unresolved identifier" means not defined...
I see, you copy readme code
Go to demo to have real code
https://github.com/dongri/OAuthSwift/blob/master/OAuthSwiftDemo/ViewController.swift

oauthswift.authorizeWithCallbackURL( NSURL(string: "http://google.com"), scope: "basic", state:"INSTAGRAM", success: {
credential, response, parameters in
println(credential.oauth_token)
},  failure: {(error:NSError!) -> Void in
            print(error.localizedDescription)
})

state:"INSTAGRAM"is for instagram
you can generate string like that

        let state: String = generateStateWithLength(20) as String

Then http://google.com is not a valid callback url, it must be an url that you must handle by url scheme (see readme and the scheme must be yourapplicationname://) or by implementing a webview and its delegate - in final OAuth2Swift.handleOpenURL(url) must be call
