Problem
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"func encode(message: String) -> String { ...XCTAssertTrue(encode(message: "TEST") == "tgst")
XCTAssertTrue(encode(message: "Mudasir") == "mWDCSKR")
XCTAssertTrue(encode(message: "YES") == "ygs")
XCTAssertTrue(encode(message: "This is a message") == "tHKS KS C MGSSCGG")
XCTAssertTrue(encode(message: "I DoNt KnOw WhAt tO WrItE") == "k dQnT kNqW wHcT Tq wRkTg")- 0.30 Compiled

way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"
Answer:
```swift
func encode(message: String) -> String {
let vowels = "aeiou"
var encodedMessage = ""
for character in message.lowercased() {
if vowels.contains(character) {
let index = vowels.firstIndex(of: character)!
let newIndex = index + 2
let newVowel = vowels[newIndex % vowels.count]
encodedMessage.append(newVowel)
} else {
encodedMessage.append(character.uppercased())
}
}
return encodedMessage
}
```let newIndex = index + 2 // cannot convert value of type 'String.Index' to expected argument type 'Int'func encode(message: String) -> String {

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.

encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

### Explanation:
This function takes a message as a string and encodes it in a way that swaps case of all letters, replaces all vowels in the message with the letter that appears 2 places ahead of that vowel in the english alphabet. It uses a for loop to iterate through each character in the message, and checks if it is a letter using the `isLetter` property. If it is a letter, it converts it to uppercase using the `uppercased()` method on the `UnicodeScalar` value, and then adds it to the result string. If it is not a letter, it simply adds it to the result string. Finally, the function returns the result string.result += String(character.unicodeScalars.first!.uppercased()) // value of type 'String.UnicodeScalarView.Element' (aka 'Unicode.Scalar') has no member 'uppercased'result += character // cannot convert value of type 'Character' to expected argument type 'String'func encode(message: String) -> String {

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"
### Response:
```swift
func encode(message: String) -> String {
var result = ""
for character in message {
if character.isLetter {
if character.isVowel {
result.append(String(character.unicodeScalars.first!) + String(character.unicodeScalars.index(of: character) + 2 < message.unicodeScalars.count? message.unicodeScalars[character.unicodeScalars.index(of: character) + 2] : message.unicodeScalars.first!))
} else {
result.append(String(character.unicodeScalars.first!) + String(character.unicodeScalars.index(of: character) + 1 < message.unicodeScalars.count? message.unicodeScalars[character.unicodeScalars.index(of: character) + 1] : message.unicodeScalars.first!))
}
} else {
result.append(character)
}
}
return result
}
```
This function first loops through each character in the input string and checks if it is a letter. If it is, it checks if it is a vowel. If it is a vowel, it appends the character that appears 2 places ahead of that vowel in the english alphabet. If it is not a vowel, it appends the character that appears 1 place ahead of that vowel in the english alphabet. If it is not a letter, it appends the character as is.
I hope this helps! Let me know if you have any questions.

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"

Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.

}### Instruction:
Write code in Swift programming language. Don't include usage examples or tests.
Write a function that takes a message, and encodes in such a
way that it swaps case of all letters, replaces all vowels in
the message with the letter that appears 2 places ahead of that
vowel in the english alphabet.
Assume only letters.
Examples:
encode(message: "test") == "TGST"
encode(message: "This is a message") == "tHKS KS C MGSSCGG"
