ios - Custom Twitter login with Swift and Parse -


i've been stuck on how implement custom twitter login parse swift app while now. resources i've seen twitter login ios objective-c, , i've tried changing suggested solutions swift, no luck far. current code:

@ibaction func twitterlogin(sender: anyobject) {     pftwitterutils.loginwithblock( { (user: pfuser?, error: nserror?) -> void in         // apparently both user , currentuser nil...         if pftwitterutils.islinkedwithuser(pfuser.currentuser()) {             var info: nsurl! = nsurl(string: "https://api.twitter.com/1.1/account/settings.json")             var request: nsmutableurlrequest = nsmutableurlrequest(url: info)             nsurlconnection.sendasynchronousrequest(request, queue: nsoperationqueue.mainqueue(), completionhandler: { (response: nsurlresponse!, data: nsdata!, connectionerror: nserror!) -> void in                 if let d = data {                     var dict: nsdictionary = nsjsonserialization.jsonobjectwithdata(d, options: nsjsonreadingoptions.mutableleaves, error: nil) as! nsdictionary                     // stuff user's profile info                 } else {                     println("apparently no twitter response.")                 }             })         } else {             println("apparently failed login.")         }     }) }

this prints out apparently failed login. i've tried this:

pftwitterutils.loginwithblock( { (user: pfuser?, error: nserror?) -> void in     if let user = user {         if user.isnew {             println("user signed , logged in twitter.")             // put information in user object             user.save()         } else {             println("user logged in twitter.")         }     } else {         println("user nil.")     } })

it printed out user nil. , tried this:

if let twitter = pftwitterutils.twitter() {     if twitter.userid != nil && twitter.screenname != nil && twitter.authtoken != nil && twitter.authtokensecret != nil {         pftwitterutils.loginwithtwitterid(twitter.userid!, screenname: twitter.screenname!, authtoken: twitter.authtoken!, authtokensecret: twitter.authtokensecret!, block: {  (user: pfuser?, error: nserror?) -> void in             if let user = user {                 if user.isnew {                     println("user signed , logged in twitter.")                     // put info in user object                     user.save()                 } else {                     println("user logged in twitter.")                 }             } else {                 println("user nil. went wrong. did user cancel login?")             }         })     } else {         println("couldn't access twitter account on device.")     } } else {     println("couldn't find twitter account on device.") }

which printed couldn't access twitter account on device. other option know of right use built-in login view controller, i'd rather use custom one. how can implement custom twitter login function?

edit: tried method didn't work yet again:

pftwitterutils.loginwithblock( { (user: pfuser?, error: nserror?) -> void in     // apparently both user , currentuser nil...     println(2)     if !(pftwitterutils.islinkedwithuser(user)) {         println(3)         pftwitterutils.linkuser(user!, block: { (succeeded: bool, error: nserror?) -> void in             println(4)             if succeeded {                 println("user linked twitter.")             }         })     }     println(5)     if let u = user {         println(6)         if u.isnew {             println("user signed , logged in twitter.")              // put info in user object              var info: nsurl! = nsurl(string: "https://api.twitter.com/1.1/account/settings.json")             println(7)             var request: nsmutableurlrequest = nsmutableurlrequest(url: info)             println(8)             nsurlconnection.sendasynchronousrequest(request, queue: nsoperationqueue.mainqueue(), completionhandler: { (response: nsurlresponse!, data: nsdata!, connectionerror: nserror!) -> void in                 println(9)                 if let d = data {                     println(10)                     var dict: nsdictionary = nsjsonserialization.jsonobjectwithdata(d, options: nsjsonreadingoptions.mutableleaves, error: nil) as! nsdictionary                     // stuff data                 } else {                     println("apparently no twitter response.")                 }             })         } else {             println("user logged in twitter.")         }     } else {         println("user nil.")     } })

this prints 3 , complains of nil optional value, user.

edit: i've been testing fabric possible solution , although provides twitter login method, can't figure out how use parse, specifically, how create , handle corresponding user object can't access user's password. i'd prefer use pftwitterutils best integration parse, i'm running out of options that. can help?
