SWIFT

difference between struct and class swift

Struct : Value Type | No Inheritance | No Deinitializers | No Type casting
Class : Reference Type | Inheritance supported | Has Deinitializers | Type casting

Common factors between struct and class:
Both allows to define properties to store values
Both allows to define methods
Both allows to define subscripts 
Both allows to define initializers
Both allows extension and protocols 

Struct Vs Class in Swift

class Bike {
  var color: String

  init(color:String) {
    self.color = color
  }
}

var bike1 = Bike(color: "Blue")

var bike2 = bike1

bike1.color = "Red"
print(bike2.color)  // prints Red
