Enumeration in Swift 4 :
Enumeration is actually used to define a common types of group of data.For example, following is a enumeration with seven different values or cases :
enum Day{
case sunday
case monday
case tuesday
case wednesday
case thrusday
case friday
case satday
}
Now, we can use one switch case to match a specific enumeration value like :
enum Day{
case sunday
case monday
case tuesday
case wednesday
case thrusday
case friday
case satday
}
let currentDay : Day = .thrusday
switch currentDay{
case .sunday:
print("Today is Sunday")
case .monday:
print("Today is Monday")
case .tuesday:
print("Today is Tuesday")
case .wednesday:
print("Today is Wednesday")
case .thrusday:
print("Today is Thrusday")
case .friday:
print("Today is Friday")
case .satday:
print("Today is Saturday")
}
It will print Today is Thrusday.
This is a basic example of enumeration in swift. I will publish one different post with some complex examples in future.__
