Chapter 2 :- Naming

How much time do you spend writing code vs reading code?!
Indeed, the ratio of time spent reading versus writing is well over 10 to 1

Names are everywhere in software.
We name our variables, our functions, our arguments, classes, and packages.
We name our source files and the directories that contain them.
We name our jar files and war files and ear files.
We name and name and name.
Because we do so much of it, we’d better do it well.
What follows are some simple rules for creating good names.

Use Intention-Revealing Names

Basically, don’t…

By default, all methods listed in a Swift protocol must be implementing in a conforming type. However, there are two ways you can work around this restriction depending on your need
The first option is to mark your protocol using the @objc attribute ( this means it can be adopted only by classes, it does mean you mark individual methods as being optional )

@objc protocol PaymentActionViews {   @objc optional  func hideView(view: UIView)
   @objc optional  func showView(view: UIView)
   func setSelectButton(button: UIButton)}

the second option
write default implementations of the optional methods that do nothing or do default implementation ( this is better option )

protocol Printable{
    func canPrint() -> Bool
}extension Printable{    func canPrint() -> Bool{
        return true
    }
}

Problem

You have a conditional that performs various actions depending on object type or properties.

• You do not have to read the following code ( it’s a piece of shit ) *

{ if canBook == false{ hideWhileCash() bookedStatus.text = "Locked" paymentTypeStack.isHidden = true process.isHidden = true } else { process.isHidden = false bookedStatus.text = "Unlocked" } if status == true{ turnPaymentOFF() if method == "cash" { self.process.isHidden = false bookedStatus.text = "Unlocked" bookedStatus.textColor = .green self.chooseCash.isHidden = true self.chooseWallet.isHidden = false showWhileOnline() payment = "online" chooseCash.backgroundColor = .orange chooseCash.setTitleColor(.white, for: .normal) } else { self.process.isHidden = true bookedStatus.text = "Locked"…

I used this summary of some key points that I made to study the book Clean Code.
I hope it helps others.

(Note: this summary doesn’t exclude the need to read the book.)

first of all , I would like to highlight a few quotes

Clean Swift VIP

Clean Swift (a.k.a VIP) is Uncle Bob’s Clean Architecture applied to iOS and Mac projects. The Clean Swift Architecture is not a framework. It is a set of Xcode templates to generate the Clean Architecture components for you. That means you have the freedom to modify the templates to suit your needs.

• View Controller
• Models
• Router
• Worker
• Interactor
• Presenter

View Controller

View Controller starts and ends the VIP cycle sends data to the Interactor though it doesn’t get responses from the Interactor This class has a one-sided interaction with the Presenter View Controller gets responses from the Presenter but can’t transfer anything…
