Answer / Neeraj Nikhra
__block is a keyword in Objective-C that allows a variable to be modified within a block. Here's an example:n```objcn__block int myVariable = 0;n-(void)myMethod {n NSBlockOperation *operation = [[NSBlockOperation alloc] init] {n myVariable++;n NSLog(@"Current value of myVariable: %d", myVariable);n };n [operation start];n}n``
