Write code in Swift programming language. Don't include usage examples or tests.
Circular shift the digits of the integer x, shift the digits right by shift
and return the result as a string.
If shift > number of digits, return digits reversed.

Answer:
```swift
func circularShift(x: Int, shift: Int) -> String {
    let digits = String(x).map { Int($0) }
    let shifted = digits.suffix(from: digits.count - shift).appending(digits.prefix(shift))
    return String(shifted.reversed())

This function uses string manipulation to rotate the digits of the integer `x`. It first converts the integer to a string, then uses string slicing to extract the last `effectiveShift` digits and the remaining digits, and finally concatenates them to form the rotated string.

If `shift` is greater than the number of digits in `x`, the function will reverse the digits of `x` since rotating by more than the number of digits is the same as rotating by the remainder of the rotation.

Note: This function assumes that `x` is a non-negative integer.

func circularShift(x: Int, shift: Int) -> String {
    let digits = String(x)
    let shift = shift % digits.count

    return shiftedDigits
}

// Example usage:
print(circularShift(x: 12345, shift: 2))  // Output: "34512"
print(circularShift(x: 12345, shift: 5))  // Output: "54321"

```

This function takes an integer `x` and a non-negative integer `shift`, and returns the result of a circular shift to the right on the digits of `x`. The shift is performed `shift` times. If `shift` is greater than the number of digits in `x`, the digits are reversed.

The function uses string manipulation to perform the circular shift efficiently.

Note: The function assumes that `x` is a non-negative integer and `shift` is a non-negative integer. If `x` is negative or `shift` is negative, the function may not behave as expected.

```

This function takes an integer `x` and an integer `shift`, and returns the result of a circular shift to the right by `shift` positions. If `shift` is greater than the number of digits in `x`, the digits are reversed. The function handles negative `x` by converting it to positive before processing.

The circular shift is defined as follows:

- If `shift` is 0, the original number is returned.
- If `shift` is positive, the last `shift` digits are moved to the beginning of the number.
- If `shift` is negative, the first `-shift` digits are moved to the end of the number.

The function ensures that the original number is not mutated.

Example usage:
```
circularShift(x: 12, shift: 1)  // Output: "21"
circularShift(x: 12, shift: 2)  // Output: "12"
circularShift(x: 1234, shift: 3)  // Output: "3412"

This function uses string manipulation to perform the circular shift. It first converts the integer to a string, then uses string slicing to extract the last n-shift characters as the right part, and the remaining characters as the left part. The left part is then concatenated with the right part to form the final string. If shift is greater than the number of digits in x, the function reverses the digits.

Note: This solution assumes that the input is a non-negative integer. If the input is negative, the function will not behave as expected.

This function uses string manipulation to perform the circular shift. The `String` type in Swift represents a sequence of characters, so we can use string slicing to extract the substring of the digits that we want to shift and concatenate them in the desired order.

This function uses string manipulation to rotate the digits of the integer `x`. The `String` type in Swift allows for easy manipulation of characters. The `suffix` and `prefix` methods are used to extract the last `effectiveShift` characters and the first `length - effectiveShift` characters respectively, and then concatenate them to form the rotated number as a string.

This function takes an integer `x` and an integer `shift` and returns a string representation of `x` with its digits circularly shifted `shift` times to the right. If `shift` is greater than the number of digits in `x`, the digits are reversed. Negative numbers are handled by reversing their digits and adding a minus sign.

    let index = shift % digits.count
    let shiftedDigits = Array(reversedDigits[index..<digits.count] + reversedDigits[0..<index])
    return shiftedDigits.joined()
}

Question:
Write code in Swift programming language. Don't include usage examples or tests.
Circular shift the digits of the integer x, shift the digits right by shift
and return the result as a string.
If shift > number of digits, return digits reversed.
circularShift(x: 12, shift: 1) == "21"
circularShift(x: 12, shift: 2) == "12"

Answer:
```swift
func circularShift(x: Int, shift: Int) -> String {
    let digits = String(x).map { String($0) }
    let reversedDigits = digits.reversed()
    let index = shift % digits.count
    let shiftedDigits = Array(reversedDigits[index..<digits.count] + reversedDigits[0..<index])
    return shiftedDigits.joined()
