Swift Xcode 6.1.1 POST Request not posting

Xcode 6.1.1 is quite an old version of Xcode, and using a newer version is recommended for the latest Swift language features and updates. However, I'll provide some guidance on how to make a POST request using Swift in Xcode 6.1.1.

To make a POST request in Swift, you'll typically use the NSURLConnection class or the NSURLSession class, depending on the level of control and functionality you require. Below are examples for both methods:

1. Using NSURLConnection:

swiftCopy code
import UIKit

func makePostRequest() {
    let url = NSURL(string: "https://example.com/api/endpoint")
    let request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"

    let postString = "key1=value1&key2=value2" // Your POST data here
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
        data, response, error in

        if error != nil {
            println("Error: \(error)")
            return
        }

        // Process the response data
        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode == 200 {
                if let responseData = data {
                    let responseString = NSString(data: responseData, encoding: NSUTF8StringEncoding)
                    println("Response: \(responseString)")
                }
            } else {
                println("HTTP Status Code: \(httpResponse.statusCode)")
            }
        }
    }

    task.resume()
}

// Call the function to make the POST request
makePostRequest()

2. Using NSURLSession (Preferred method in newer versions of Xcode):

swiftCopy code
import UIKit

func makePostRequest() {
    let url = NSURL(string: "https://example.com/api/endpoint")
    let request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"

    let postString = "key1=value1&key2=value2" // Your POST data here
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

    let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
    let session = NSURLSession(configuration: sessionConfig)

    let task = session.dataTaskWithRequest(request) {
        data, response, error in

        if error != nil {
            println("Error: \(error)")
            return
        }

        // Process the response data
        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode == 200 {
                if let responseData = data {
                    let responseString = NSString(data: responseData, encoding: NSUTF8StringEncoding)
                    println("Response: \(responseString)")
                }
            } else {
                println("HTTP Status Code: \(httpResponse.statusCode)")
            }
        }
    }

    task.resume()
}

// Call the function to make the POST request
makePostRequest()

Make sure to replace the url variable with the actual URL of the API endpoint you want to send the POST request to. Also, modify the postString variable to contain your POST data in the appropriate format (e.g., JSON, form-urlencoded, etc.).

Again, I strongly recommend using a more recent version of Xcode and Swift for the best development experience and access to the latest language features and frameworks.
