Monitor memory usage in your Swift application

LogSnag is a monitoring service that alerts you when your application is experiencing high memory usage.

A common problem that we often face with Swift applications is memory leaks and the overall memory usage of our application. This is a significant problem when building applications that we end up deploying to the cloud either as a serverless function, container, or virtual machine. In such cases, memory usage can become a significant problem by slowing down our application, causing it to crash entirely, or increasing costs.

Therefore, monitoring our Swift application's memory usage and setting up a system to track when use goes above a certain threshold is essential. This way, we can always be aware of the performance of our application. In cases of a performance issue, for example, when the memory usage goes above a certain threshold, say 80 percent, we can take immediate action and fix the problem before it becomes a significant issue.

To do so, we have created LogSnag, a powerful event tracking tool that works seamlessly with Swift and allows us to track any event in our application in real-time. For example, with LogSnag, we can track our memory usage in real-time and set up a rule to notify our team and us when the memory usage goes above a certain threshold via push notifications. This way, we will always be aware of the performance of our application, and we can take immediate action if needed.

Swift code snippets

You can use the following code snippets to track memory usage in your Swift application. Please don't forget to replace the YOUR_API_TOKEN with your API token and update the project and channel names.

Using Swift with URLSession
import Foundation
#if canImport(FoundationNetworking)
import FoundationNetworking
#endif

var semaphore = DispatchSemaphore (value: 0)

let parameters = "{\"project\":\"my-saas\",\"channel\":\"status\",\"event\":\"High Memory Usage\",\"description\":\"Memory usage has exceeded the threshold.\",\"icon\":\"🚨\",\"notify\":true}"
let postData = parameters.data(using: .utf8)

var request = URLRequest(url: URL(string: "https://api.logsnag.com/v1/log")!,timeoutInterval: Double.infinity)
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("Bearer YOUR_API_TOKEN", forHTTPHeaderField: "Authorization")

request.httpMethod = "POST"
request.httpBody = postData

let task = URLSession.shared.dataTask(with: request) { data, response, error in 
  guard let data = data else {
    print(String(describing: error))
    semaphore.signal()
    return
  }
  print(String(data: data, encoding: .utf8)!)
  semaphore.signal()
}

task.resume()
semaphore.wait()
