Unable to connect to parse after recent update - ios

Question

Since the latest update, I get the error
"libc++abi.dylib: terminating with uncaught exception of type
NSException
(lldb)"
whenever I try to connect to parse
I can't even perform a simple task like create a user, as it will always crash. I suspect something changed after Xcode's recent update, and I cannot figure out what it is.
I suspect it could be the libc++abi.dylib library not been supported, but I don't know what to do about this.
Here's my View controller
import UIKit
import Parse
class ViewController: UIViewController {
#IBOutlet var username: UITextField!
#IBOutlet var password: UITextField!
func displayAlert(title: String, message: String) {
let alertcontroller = UIAlertController(title: title, message: message, preferredStyle: .alert)
alertcontroller.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alertcontroller, animated: true, completion: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func signup(_ sender: Any) {
if username.text == "" || password.text == "" {
displayAlert(title: "Error in Form", message: "Please fill in the information")
} else {
let user = PFUser()
user.username = username.text
user.password = password.text
}
}
Here's my App Delegate
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
//--------------------------------------
// MARK: - UIApplicationDelegate
//--------------------------------------
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Enable storing and querying data from Local Datastore.
// Remove this line if you don't want to use Local Datastore features or want to use cachePolicy.
Parse.enableLocalDatastore()
let parseConfiguration = ParseClientConfiguration(block: { (ParseMutableClientConfiguration) -> Void in
ParseMutableClientConfiguration.applicationId = "......"
ParseMutableClientConfiguration.clientKey = "......"
ParseMutableClientConfiguration.server = "........"
})
Parse.initialize(with: parseConfiguration)
