Xcode use of unresolved Identifier error

Question

I am new to Xcode so I didn't get how to resolve this error by reading other articles in StackOverflow related to this. Basically I am working on the CoreData part and the following code accesses Amount, Bank Name and Title field but it's giving this error.

Answer 1

The first four lines in your code are outside any context. You can't do that. No executable code can appear except inside a function — usually, some method of some class.

So those four lines need to be inside the ViewController class, not before it, and again, not just loose inside it, but in some method of the ViewController class.
