Class ‘ViewController’ has no initializers in swift

by

The error could be improved, but the problem with your first version is you have a member variable, delegate, that does not have a default value. All variables in Swift must always have a value. That means that you have to set it up in an initializer which you do not have or you could provide it a default value in-line.

When you make it optional, you allow it to be nil by default, removing the need to explicitly give it a value or initialize it.
