XCode 8 Compiled Apps Wont Run In Simulator

I am working on an app in XCode 8, but when I try to run it in the simulator, it fails with an error on line 12 of AppDelegate.swift. I have not modified this file at all.

//

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {  // ERROR IS THROWN HERE (Thread 1: signal SIGABRT)
    var window: UIWindow?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        return true
    }
    func applicationWillResignActive(_ application: UIApplication) {
    }
    func applicationDidEnterBackground(_ application: UIApplication) {
    }
    func applicationWillEnterForeground(_ application: UIApplication) {
    }
    func applicationDidBecomeActive(_ application: UIApplication) {
    }
    func applicationWillTerminate(_ application: UIApplication) {
    }
}

The error on that line is Thread 1: signal SIGABRT. When ran, the simulator freezes on the static launchscreen (which is a storyboard, and is set correctly in info.plist).

If I click on Thread 1, the one where SIGABRT originates from, then click on 0 __pthread_kill I get this:

libsystem_kernel.dylib`__pthread_kill:
    0x107bb5dd0 <+0>:  movl   $0x2000148, %eax          ; imm = 0x2000148

    0x107bb5de5 <+21>: nop
    0x107bb5de6 <+22>: nop
    0x107bb5de7 <+23>: nop

Theres a nice error on line 4 saying < Thread 1: signal SIGABRT >.

Also, under Thread 1, 11 UIApplicationMain, there is the following, with the same error on line 47: (This probably isnt useful, but, maybe)

12 main under thread one just takes me to the AppDelegate.swift

13 start gives me the same error on line 3:

libdyld.dylib`start:

    0x1078596c4 <+8>: hlt 

14 start gives me the same errror on line 3:

libdyld.dylib`start:

If it would be helpfull, I can post my ViewController.
