### Response:
```swift
func countUpper(s: String) -> Int {
    let vowels: Set<Character> = ["A", "E", "I", "O", "U"]
    return s.indices.filter { s[$0].isUppercase && s[$0].isVowel && $0 % 2 == 0 }.count
}
```

func countUpper(s: String) -> Int {
    let vowels: Set<Character> = ["A", "E", "I", "O", "U"]
    var count = 0
    for (index, char) in s.enumerated() {

```

This code defines a function `countUpper` that takes a string `s` as input and returns the number of uppercase vowels in even indices of the string. The function iterates over the string and checks if each character is an uppercase vowel at an even index. If it is, it increments the count. The function returns the total count of uppercase vowels at even indices.

To use the function, you can call it with a string as an argument:

```swift
let exampleString = "aBCdEf"
let upperCount = countUpper(s: exampleString)
print("Number of uppercase vowels in '\(exampleString)' at even indices: \(upperCount)")
```

This will output:

```
Number of uppercase vowels in 'A B C D E F' at even indices: 1
```

This code defines a function `countUpper` that takes a string `s` as input and returns the number of uppercase vowels in even indices of the string. The function iterates over each character in the string, checks if it is an uppercase vowel and if it's at an even index, and increments the count if both conditions are met. The function then returns the count.

The function is called with an example string `"aBCdEf"` and the result is printed to the console.

The function iterates over each character in the string, checks if it is an uppercase vowel and if it is in an even index, and increments the count if both conditions are met. The function then returns the count.

To use the function, you can call it with a string as an argument:

```swift
let exampleString = "aBCdEf"
let upperCount = countUpper(s: exampleString)
print("Number of uppercase vowels in even indices: \(upperCount)")
```

This will output:

```
Number of uppercase vowels in even indices: 1
