Realm EXC_BAD_ACCESS when querying database - realm

Question

Im new to realm. I have read the documentation and followed the examples in creating and querying the database. Whenever I run the code below it crashes on the line
let realm = Realm
I have a view controller that I am trying to query realm like so:
// Get the default Realm
let realm = Realm()
// Query using an NSPredicate
let predicate = NSPredicate(format: "s3_url = %#", s3_url)
let medias = realm.objects(MediaRealm).filter(predicate)
everytime i run this i get Thread1: EXC_BAD_ACCESS
let realm = Realm()
import UIKit
import Alamofire
import RealmSwift
class ViewController: UIViewController {
let mediaCollection = MediaCollection()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
loadInitialData()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func loadInitialData(){
//connect to url
mediaCollection.fetch(onSuccess:{ self.onEventFetched($0) }, onError:{ self.displayAlert($0)})
}
func onEventFetched()->Void{
println("Got stuff")
println(mediaCollection.models.count)
processCollection()
}
func processCollection()->Void{
for media in mediaCollection.models{
let m = media as! Media
println(m.s3_url)
println(m.title)
if let s3_url = m.s3_url{
//query database, if it already exists dont download it
// Get the default Realm
let realm = Realm()
// Query using an NSPredicate
let predicate = NSPredicate(format: "s3_url = %#", s3_url)
let medias = realm.objects(MediaRealm).filter(predicate)
if medias.count == 0 {
println("no files found")
//downloadFile(s3_url)
}
}
}
}
What am I doing wrong?

Answer 1

This was caused by me adding new fields to the database and not running a migration.
Solution was to delete the app and start over.
