How to solve Command failed due to signal: Segmentation fault: 11 - ios

Question

I was searching for this issue here, and found out that this issue is not common one.
Everyone had different approaches to solve it. I'm using Firebase and Gifu framework. Actually for the last one - i copied all the files to my project, but that didn't helped either.
Here is my source code:
import FirebaseDatabase
import FirebaseAuth
import Firebase
import UIKit
import Gifu
class ViewController: UIViewController {
#IBOutlet weak var userImage: AnimatableImageView!
var displayedUserId = ""
var AcceptedOrRejected = ""
override func viewDidLoad() {
super.viewDidLoad()
let urlArray = ["http://i.imgur.com/VAWlQ0S.gif", "http://i.imgur.com/JDzGqvE.gif", "http://67.media.tumblr.com/4cd2a04b60bb867bb4746d682aa60020/tumblr_mjs2dvWX6x1rvn6njo1_400.gif", "https://media.giphy.com/media/TlK63ELk5OPDzpb6Tao/giphy.gif", "http://i3.photobucket.com/albums/y90/spicestas/GeriHalliwell-Calling-new1.gif", "http://media.tumblr.com/tumblr_lnb9aozmM71qbxrlp.gif"]
var counter = 1
for url in urlArray {
let nsUrl = NSURL(string: url)
let girls = ProfileClass()
girls.profilePhotoUrl = url
girls.profileGender = "female"
girls.profileName = "girlsname\(counter)"
girls.profileSurname = "girlsurname\(counter)"
girls.interest = "men"
girls.uid = "\(randomStringWithLength(45))"
counter++
girls.SaveUser()
}
//----setting variables
let label = UILabel(frame: CGRectMake(self.view.bounds.width / 2 - 100, self.view.bounds.height / 2 - 50, 300, 100))
//label.text = "Drag me!"
//label.textAlignment = NSTextAlignment.Center
self.view.addSubview(label)
let gesture = UIPanGestureRecognizer(target: self, action: Selector("wasDragged:"))
userImage.addGestureRecognizer(gesture)
userImage.userInteractionEnabled = true
//----getting access to database
let thisUserRef = URL_BASE.childByAppendingPath("profile")
thisUserRef.queryOrderedByChild("Interest").queryEqualToValue("men").observeEventType(.Value, withBlock: {
snapshot in
for child in snapshot.children{
self.displayedUserId = (child.value["uid"] as? String)!
let imageURL = child.value["photo"] as? String
let imURL = NSURL(string: imageURL!)
//print(imageURL)
if self.AcceptedOrRejected != "" {
let AcceptedArray = child.value[AcceptedOrRejected] as? Array
AcceptedArray.append(displayedUserId)
}
if let picData = NSData(contentsOfURL: imURL!) {
self.userImage.animateWithImageData(picData)
//self.userImage.image = UIImage(data: picData)
}
}
})
}
//-----Dragging function-----------
func wasDragged(gesture: UIPanGestureRecognizer) {
//set traslations
let translation = gesture.translationInView(self.view)
let label = gesture.view
//set center position
label!.center = CGPoint(x: self.view.bounds.width / 2 + translation.x, y: self.view.bounds.height / 2 - translation.y )
let xfromCenter = (label?.center.x)! - self.view.bounds.width / 2
let scale = min(100 / abs(xfromCenter),1)
var rotation = CGAffineTransformMakeRotation(xfromCenter / 200)
var strech = CGAffineTransformScale(rotation, scale, scale)
label?.transform = strech
if gesture.state == UIGestureRecognizerState.Ended {
if label?.center.x < 100 {
self.AcceptedOrRejected = "Accepted"
} else if label?.center.x > self.view.bounds.width / 100 {
self.AcceptedOrRejected = "Rejected"
}
rotation = CGAffineTransformMakeRotation(0)
strech = CGAffineTransformScale(rotation, 1, 1)
label?.transform = strech
label?.center = CGPoint(x: self.view.bounds.width / 2 , y: self.view.bounds.height / 2 )
}
}
//---Function for generating randomn userid
func randomStringWithLength (len : Int) -> NSString {
let letters : NSString = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
let randomString : NSMutableString = NSMutableString(capacity: len)
for (var i=0; i < len; i += 1){
let length = UInt32 (letters.length)
let rand = arc4random_uniform(length)
randomString.appendFormat("%C", letters.characterAtIndex(Int(rand)))
}
return randomString
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "LogOutSegue" {
try! FIRAuth.auth()!.signOut()
}
}
}
And I get this error

}
if let picData = NSData(contentsOfURL: imURL!) {
self.userImage.animateWithImageData(picData)
//self.userImage.image = UIImage(data: picData)

}
}"
I don't really know what to do with that

Answer 1

I just attempted a conversion to Swift 3 to get a jump on fixing issues in my code. I have similar error but I just integrated Firebase into all of my project. I found that by removing the pod and framework from the app and commenting out all firebase code fixed this compile issue.
