Swift and using class extension

by

For me it seems completely reasonable since you can use extensions to expose different parts of logic to different extensions. This can also be used to make class conformance to protocols more readable, for instance

class ViewController: UIViewController {
...
}

extension ViewController: UITableViewDelegate {
...
}

extension ViewController: UITableViewDataSource {
...
}

extension ViewController: UITextFieldDelegate {
...
}

Protocol methods are separated in different extensions for clarity, this seems to be far better to read than lets say:

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UITextFieldDelegate {}

So, I’d say there’s no harm in using extensions to make your own code more readable, not just to extend already existing classes from SDK. Using extensions you can avoid having huge chunks of code in your controllers and split functionality into easily readable parts, so there’s no disadvantage of using those.
