Recap - Validation Function
Part of the Fundamentals section of Coddy's Swift journey — lesson 56 of 86.
Challenge
EasyisValidPassword that takes password and minLength and returns whether the password meets the validation criteria.
A password is valid if it satisfies all of the following conditions:
Conditions:
- The password length must be at least
minLengthcharacters - The password length must not exceed 20 characters
- The password must not be equal to
"password"(case-sensitive)
Parameters:
password(String): The password to validateminLength(Int): The minimum required length
Returns: true if all conditions are met, false otherwise (Bool)
For example, if password is "Swift123" and minLength is 6, the function returns true because the password is 8 characters (at least 6), not more than 20, and not equal to "password".
Try it yourself
func isValidPassword(password: String, minLength: Int) -> Bool {
// Write code here
}
