shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Answer:
```swift
func encrypt(s: String) -> String {
    let alphabet = "abcdefghijklmnopqrstuvwxyz"
    var encrypted = ""
    
    for char in s {
        if let index = alphabet.firstIndex(of: char) {
            let newIndex = index + 2 * 2
            encrypted.append(alphabet[newIndex % alphabet.count])
        } else {
            encrypted.append(char)
        }
    }
    
    return encrypted
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Answer:
```swift
func encrypt(s: String) -> String {
    let alphabet = "abcdefghijklmnopqrstuvwxyz"
    let encrypted = s.map { character in
        let index = alphabet.firstIndex(of: character)?? 0
        let newIndex = (index + 2 * 2) % alphabet.count
        return alphabet[newIndex]
    }
    return String(encrypted)
}

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated.

shift down by two multiplied to two places.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

This code defines a function `encrypt` that takes a string `s` as an argument and returns a new string where each letter in `s` is shifted down by four places in the alphabet. The function uses a for-loop to iterate over each character in `s`, checks if the character is in the alphabet using the `firstIndex(of:)` method, and if it is, finds the new index by using the `index(offsetBy:)` method. The new character is then appended to the `encryptedString`. If the character is not in the alphabet, it is appended to the `encryptedString` without being encrypted. The function finally returns the `encryptedString`.

func encrypt(s: String) -> String {
    let alphabet = "abcdefghijklmnopqrstuvwxyz"

This code defines a function `encrypt` that takes a string `s` as an argument and returns a new string `encryptedString`. It iterates over each character in `s`, finds its index in the alphabet string, and then appends the character at the new index (which is the original character index plus 4) to `encryptedString`. If the character is not found in the alphabet string, it is appended to `encryptedString` without encryption. The function then returns `encryptedString`.

func encrypt(s: String) -> String {
    let alphabet = "abcdefghijklmnopqrstuvwxyz"
    var encryptedString = ""
    
    for char in s {
        if let index = alphabet.firstIndex(of: char) {

This Swift function `encrypt` takes a string `s` as an argument and returns a new string `encryptedString` where each character in `s` is replaced by the character in the alphabet that is four places down from the original character. If the character is not in the alphabet, it is appended to `encryptedString` without being replaced. The function then returns `encryptedString`.

Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"<|im_end|>

Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated.

encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"<end_of_turn>

Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"<end_of_turn>

shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Answer:
```swift
func encrypt(s: String) -> String {
    var result = ""
    for char in s {
        let charCode = Int(char.asciiValue!)
        let newCharCode = (charCode + 2 * 2) % 26
        result.append(Character(UnicodeScalar(newCharCode)!))
    }
    return result
}
```

func encrypt(s: String) -> String {
    var result = ""
    for char in s {
        let index = Int(String(char).unicodeScalarValue) - 97
        let newIndex = (index + 2 * 2) % 26
        result.append(String(UnicodeScalar(newIndex + 97)))
    }
    return result
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Create a function encrypt that takes a string as an argument and
returns a string encrypted with the alphabet being rotated. 
The alphabet should be rotated in a manner such that the letters 
shift down by two multiplied to two places.
For example:
encrypt(s: "hi") == "lm"
encrypt(s: "asdfghjkl") == "ewhjklnop"
encrypt(s: "gf") == "kj"
encrypt(s: "et") == "ix"

Answer:
```swift
func encrypt(s: String) -> String {
    var result = ""
    for char in s {
        let index = Int(String(char).unicodeScalarValue) - 97
        let newIndex = (index + 2 * 2) % 26
        result.append(String(UnicodeScalar(newIndex + 97)))
    }
    return result
}
```

func encrypt(s: String) -> String {
    var encrypted = ""
    for char in s {
        let charCode = Int(String(char).unicodeScalar(at: 0))!
        let newCharCode = (charCode + 2 * 2) % 26
        encrypted += String(UnicodeScalar(newCharCode)!).lowercased()
    }
    return encrypted
}
