EXC_BAD_ACCESS on device ONLY - xcode

Question

So after updating xCode to version 7.1 this morning, my project suddenly crashes and throws "EXC_BAD_ACCESS (CODE = 1)" anytime I access any part of an object in a submodule but ONLY when I build on an iOS device. In simulator, I can't reproduce the issue. I've checked for zombie objects in instruments and the app just crashes without producing any warning in instruments like it would when a zombie is found. I've cloned a new version of my repo and re-added the submodule thinking maybe it had something to do with xCode itself but the issue still persists. I decided I would try to access the object in appDelegate and even there, I get the same result. Here is where the issue was originally presented:
As you can see, there is absolutely no information as to what's causing it. I move up the stack trace and everything is in assembly. Abstract User is part of a submodule but has never presented any problems until the last update. Here is the stack trace:

I've tried everything I can think of and followed numerous tutorials and debugging Bad Access errors and nothing helps. I almost feel like it's an Xcode issue but I have no idea. Here is the AbstractUser class if it helps:
public class AbstractUser: ServiceModel {
/// Date of last login
private(set) var lastLogin = NSDate()
/// Password (please, don't use this field stupidly...)
private(set) var password = String.empty
public struct SerializationKeys {
public static let lastLogin = "last_login"
public static let password = "password"
}
// MARK: - Copyable
public required init(source: Copyable) {
super.init(source: source)
let u = source as! AbstractUser
lastLogin = u.lastLogin
password = u.password
}
// MARK: - JSONSerializable
public required init(dictionary: [String : AnyObject]) {
super.init(dictionary: dictionary)
lastLogin = lastLogin <|? dictionary[SerializationKeys.lastLogin]
password = password <|? dictionary[SerializationKeys.password]
}
public override func toDictionary() -> [String : AnyObject] {
var dictionary = super.toDictionary()
dictionary[SerializationKeys.lastLogin] = lastLogin.toString()
dictionary[SerializationKeys.password] = password
return dictionary
}
// MARK: - ModelType
public override func updateObject(newVersion: ModelType) {
super.updateObject(newVersion)
let u = newVersion as! AbstractUser
lastLogin = u.lastLogin
password = u.password
}
// MARK: - NSCoding
#objc public required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
lastLogin = lastLogin <|? aDecoder.decodeObjectForKey(SerializationKeys.lastLogin)
password = password <|? aDecoder.decodeObjectForKey(SerializationKeys.password)
}
#objc public override func encodeWithCoder(aCoder: NSCoder) {
super.encodeWithCoder(aCoder)
aCoder.encodeObject(lastLogin, forKey: SerializationKeys.lastLogin)
aCoder.encodeObject(password, forKey: SerializationKeys.password)
}
}
Also the User object is a subclass of AbstractUser and isn't the cause of the problem. It will produce the same error however just putting print(keys) after "let keys = ..." will cause the error just the same. The issue seems to be when I try and access any property or method on any class within that submodule.
