How do I secure requests with ATS and TLS in Swift?

To secure requests in Swift using App Transport Security (ATS) and Transport Layer Security (TLS), you need to make sure your application is configured properly to comply with security standards. Here’s a brief guide on how to implement ATS and ensure TLS encryption for your network requests.

Configuring App Transport Security (ATS)

ATS is designed to improve the security of your app’s network connections by enforcing the use of HTTPS, which uses TLS. By default, ATS requires secure connections. However, if you need to allow HTTP connections temporarily, you can modify your Info.plist file. Here’s how to add exceptions:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict> </dict> </plist>

Making Secure Network Requests

To ensure your requests are secure, always use HTTPS URLs. Here’s an example of making a network request using URLSession with proper error handling:

let url = URL(string: "https://api.example.com/data")! let task = URLSession.shared.dataTask(with: url) { data, response, error in if let error = error { print("Error: \(error)") return } guard let data = data else { print("No data available") return } // Handle the response data print("Received data: \(data)") } task.resume()
