Swift Question

Errors thrown from here are not handled for do { } catch in Swift 2.0

After i update swift 2.0 i got an error with do { try } catch like an image below.

enter image description here

How can i fix this?

The error is telling you that the enclosing catch is not exhaustive. This is because the auto-generated catch block is only catching NSError objects, and the compiler can't tell whether some other ErrorType will be thrown.

If you're sure no other errors will be thrown, you can add another default catch block:

do {
    objects = try managedObjectContext?.executeFetchRequest(request)
} catch let error1 as NSError {
    error = error1
    objects = nil
} catch {
    // Catch any other errors
