Password Strength V6 - Scored 0-100 in Swift

Practice

Combine the earlier checks into a single numeric score between 0 and 100.

You start with:

let password = "Secret!99"

Build:

Length: 9
Score: 100

Rules:

Start the score at 0.
If the length is at least 8, add 25.
If the password contains an uppercase letter, add 20.
If it contains a lowercase letter, add 20.
If it contains a digit, add 20.
If it contains a symbol (not a letter and not a digit), add 15.
Print "Length: " followed by the length, then print "Score: " followed by the score.

Try other passwords: with abc123 the output is

Length: 6
Score: 40

Use the same character property checks, then accumulate into var score.

let password = "Secret!99"

let length = password.count
var hasUpper = false
var hasLower = false
var hasDigit = false
var hasSymbol = false
for character in password {
    if character.isUppercase {
        hasUpper = true
    }
    if character.isLowercase {
        hasLower = true
    }
    if character.isNumber {
        hasDigit = true
    }
    if !character.isLetter && !character.isNumber {
        hasSymbol = true
    }
}
var score = 0
if length >= 8 {
    score += 25
}
if hasUpper {
    score += 20
}
if hasLower {
    score += 20
}
if hasDigit {
    score += 20
}
if hasSymbol {
    score += 15
}
print("Length: \(length)")
print("Score: \(score)")
