Initial version of "export as markdown" functionality

[pd95]

This is a preview of a possible "export" functionality.

• a "share button" in the chat's toolbar triggers the save dialog (using fileExporter)
• the chat with its messages and some statistics is "rendered manually" into a markdown string
• the string is saved using the Transferable protocol

Happy to receive feedback...

For each message:

• the prompt is rendered into a markdown "quote block", so indenting the users input.
• the response is checked for a <think> block. If found, this part is put into a quote block as the users input.
• the rest of the response is added "as is" (as we expect it to be proper markdown)

There are known issues:

• if the prompt contains markdown formatting, this might look ugly/break
• HTML entities are only escaped in the <think> block. But if the < & or > are already escaped in markdown (using backticks ` or ```) this is incorrect.

Attached here is a sample export done using this code.

Below you see how Github is rendering it.

Swift Function to Check Prime Numbers in Swift Code

What is a prime number? Give me a Swift function implementing "isPrime".

What is a Prime Number?

A prime number is a positive integer that is divisible only by itself and 1. In other words, it has exactly two distinct factors: 1 and the number itself.

For example, the first few prime numbers are:

2, 3, 5, 7, 11, 13, ...

Swift Function Implementing "isPrime"

Here's a simple Swift function that checks whether a given integer is a prime number or not:

/// Checks if a given integer is a prime number.
///
/// - Parameter n: The number to check for primality.
/// - Returns: `true` if the number is prime, `false` otherwise.
func isPrime(_ n: Int) -> Bool {
    guard n > 1 else { return false }
    
    for i in 2...Int(sqrt(Double(n))) {
        if n % i == 0 {
            return false
        }
    }
    return true
}

Explanation

This function works by checking divisibility of the input number n from 2 up to its square root. If n is divisible by any of these numbers, it's not prime.

Here's a step-by-step breakdown:

1. We first check if n is less than or equal to 1, in which case it's not prime.
2. We then iterate from 2 up to the square root of n. For each iteration, we check if n is divisible by the current number i.
3. If n is divisible by i, we immediately return false, indicating that n is not prime.
4. If we reach the end of the loop without finding a divisor, we return true, indicating that n is prime.

Example Use Cases

You can use this function to check whether a given integer is prime:

print(isPrime(25)) // prints: false
print(isPrime(23)) // prints: true

Note that this implementation has a time complexity of O(√n), making it relatively efficient for large inputs. However, for extremely large numbers, you may need to use more advanced primality tests or libraries.
