Swift Nested If

Swift Nested If

Nest if statements to check multiple levels of conditions.

Use nested conditions for multi-step checks

Use nested conditions to handle layered checks, such as authentication then role.

let isLoggedIn = true
let isAdmin = false
if isLoggedIn {
    if isAdmin {
      print("Admin panel")
    } else {
      print("Limited access")
    }
  }

Use nested conditions to handle layered checks, such as authentication then role.

Validate and Branch

Validate inputs first, then use a nested if to branch inside the valid case.

let score = 85
if score >= 0 && score <= 100 {
  if score >= 90 {
    print("A")
  } else if score >= 80 {
    print("B")
  } else if score >= 70 {
    print("C")
  } else {
    print("Below C")
  }
} else {
  print("Invalid score")
}
