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.

Example

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.

Example

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")
}
