Hello
When I try to run the simulator I get this:

Can someone help me please?

Probably you should post your definition of the region itself in XCode to help us help you. A stack trace like this above is hard to decipher unless you are very familiar with the product (therefore don’t need this class!)

Never mind, I find the solution, I just initialized the struct with some value

CLLocationCoordinate2D noLocation = CLLocationCoordinate2DMake(0,0);

Cheers,
