because of this i am getting nil value in all like name text retweet please tell me how to solve this

 var timeline = (FHSTwitterEngine.shared().getTimelineForUser(FHSTwitterEngine.shared().authenticatedUsername, isID: true, count: 10), terminator: "")

from this line i am getting whole response

and then i have on array i create and store in to array like below

var serviceData = [AnyObject]()
let timelinedata = [timeline] as [AnyObject]
serviceData = (timelinedata)
print(serviceData)

Answer 1

In general, anything optional can be unwrapped like so:

let optionalValue: String? = "Hello, this is optional!"

if let noLongerOptional = optionalValue {
    print("\(noLongerOptional) no its not! ahah")
}

---

Edit: more specific example...

Assuming you have a variable 'myJson' which hold your optional value... and you did:

print("\(myJson)")

You can solve this by:

if let validJson = myJson {
  print("\(validJson)")
}

---

Edit 2: ... FHSTwitter... (updated.... this is getting long)

let twitterEngine = FHSTwitterEngine.sharedEngine()
let twitterUser = twitterEngine.authenticatedID
let timeline = twitterEngine.getTimelineForUser(twitterUser, isID: true, count: 10)

According to FHSTwitterEngine docs... getTimelineForUser() will return either a NSError or an array of Tweets.

so...

if let error = timeline as? Error {
  print("Oops, looks like something went wrong: \(error)")
} else {
  if let tweets = timeline as? [Any] {
    for tweet in tweets {
       print("This is a tweet: \(tweet)")
    }
  }
}

If you have any more trouble using FHSTwitterEngine, I suggest you play with: https://github.com/natesymer/FHSTwitterEngine/tree/master/FHSTwitterEngineDemoSwift/Demo-Swift

Or open a support ticket with the FHSTwitterEngine developer(s) at: https://github.com/natesymer/FHSTwitterEngine/issues

Good Luck!
