Accessing Local file using NSURL

I am trying to access an XML file store in the resources directory. I am using NSURL to access this file using NSURLConnection( this file is going to be swapped out for a remote service in the future).

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL 
URLWithString:@"file:///XMLTest.xml"] 
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

NSURLConnection *connection=[[NSURLConnection alloc] initWithRequest:request delegate:self];
if (connection) {
    // Create the NSMutableData to hold the received data.
    // receivedData is an instance variable declared elsewhere.
    response = [[NSMutableData data] retain];
} else {
    NSLog(@"Could not create connection");
}

The class that starts the connection implements the NSURLConnection methods:

connection:willCacheResponse: 
connection:didReceiveData: 
connectionDidFinishLoading: 
connectionDidFinishLoading:

Once I launch this the simulator dies, no messages are printed to the console so I am at a loss for where to look. Any ideas, or am I just doing this completely wrong?

This would also work:

Obj-C

NSString *path = [[NSBundle mainBundle] pathForResource:@"XMLTest" ofType:@"xml"];

Swift 5

let url = Bundle.main.url(forResource: "XMLTest", withExtension: "xml")!
