Xcode 6 iPhone Simulator Application Support location

I would suggest that you use SimPholders to find your Simulator files. It is a menu bar item that tracks your simulator apps and lets you go directly to their folders and content. It's awesome.

To know where your .sqlite file is stored in your AppDelegate.m add the following code

- (NSURL *)applicationDocumentsDirectory
{
    NSLog(@"%@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory      inDomains:NSUserDomainMask] lastObject]);

    return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory     inDomains:NSUserDomainMask] lastObject];
 }

now call this method in AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

  //call here
   [self applicationDocumentsDirectory];

}

The simulator directory has been moved with Xcode 6 beta to...

~/Library/Developer/CoreSimulator

Browsing the directory to your app's Documents folder is a bit more arduous, e.g.,

~/Library/Developer/CoreSimulator/Devices/4D2D127A-7103-41B2-872B-2DB891B978A2/data/Containers/Data/Application/0323215C-2B91-47F7-BE81-EB24B4DA7339/Documents/MyApp.sqlite

I found SimulatorManager application very useful. It takes you directly to the application folder of installed simulators. I have tried with 7.1, 8.0 and 8.1 simulators.

SimulatorManager resides as an icon in the system tray and provides an option to "Launch At Login".

Note: This works only with Xcode 6 (6.1.1 in my case) and above.

Hope that helps!
