?? Embracing the SOLID Principles in SwiftUI: Because Code Shouldn’t Be a Jigsaw Puzzle ??

Hey, SwiftUI enthusiasts! Today, let’s chat about the ?????????? principles. If your code feels more like a tangled mess than a smooth-running app, these principles are your best friends!?

Single Responsibility Principle (SRP)

Every class should have one job. Think of it like a barista who only makes lattes instead of trying to juggle making lattes, pastries, and giving motivational speeches. ??

Example:?

struct CoffeeView: View {
  var body: some View {
    Text("Brewing the perfect latte!")
  }
}        

Open/Closed Principle (OCP)??

Software entities should be open for extension but closed for modification. Just like your favourite TV show: we want new seasons, not a complete reboot! ??

Example:??

protocol Coffee {
  func brew() -> String
}

struct Espresso: Coffee {
  func brew() -> String {
    return "Espresso is brewing!"
  }
}        

Liskov Substitution Principle (LSP)??

If a subclass can't substitute its parent class without breaking things, you've got a problem! It’s like trying to use a cat as a guide dog. ??????

Example:??

class CoffeeMaker {
  func makeCoffee() -> String {
    return "Making coffee!"
  }
}

class DecafCoffeeMaker: CoffeeMaker {
  override func makeCoffee() -> String {
    return "Making decaf coffee!"
  }
}        

Interface Segregation Principle (ISP)??

Clients should not be forced to depend on interfaces they do not use. Imagine forcing a cat to play fetch—no thanks! ??

Example:??

protocol CoffeeMachine {
  func brew()
}

protocol CleaningMachine {
  func clean()
}

class EspressoMachine: CoffeeMachine, CleaningMachine {
  func brew() { /* brewing logic */ }
  func clean() { /* cleaning logic */ }
}        

Dependency Inversion Principle (DIP)??

High-level modules should not depend on low-level modules. Both should depend on abstractions. It’s like having a smartphone depend on apps, not the hardware! ??

Example:??

class CoffeeShop {
  var coffee: Coffee
  init(coffee: Coffee) {
    self.coffee = coffee
  }
}        

By applying these SOLID principles, your SwiftUI code will be cleaner, more maintainable, and much easier to understand. Let’s make coding as enjoyable as a well-brewed cup of coffee! ????
