A Day in the Life of a Swift Developer: From a Cup of Coffee to Deploying to the App Store

What a Typical Workday of a Swift Developer Looks Like in 2025

When I first started learning Swift, I thought iOS developers were like wizards who write perfect code from morning to night over a latte in a stylish coworking space. The reality, as you might guess, turned out to be more prosaic, but no less interesting.

In this article, I'll walk you through a typical workday of a Swift developer — from morning coffee to an evening push to the App Store. You'll see not only the schedule but also real code snippets we deal with every day. Let's go!

09:00 — Morning: Daily Stand-up and Planning

The day starts with a short standup in Zoom or Slack. Our team consists of 5 iOS developers, two backend developers, and a product manager. Each person speaks for 1-2 minutes: what was done yesterday, what is planned for today, and if there are any blockers.

A typical response from me sounds like this:

\n
• Yesterday: Finished refactoring the authorization module using Combine.
\n
• Today: Integrating a new profile screen with SwiftUI, need to implement the transition animation.
\n
• Blocker: Waiting for the final mockups for the dark theme from the designer.
\n

After the standup — 15 minutes to review messages in Jira and GitHub. I check which PRs require my review and read comments on my pull requests.

09:45 — First Deep Work: New Functionality

Morning is the best time for complex tasks. Today I'm writing a Push Notification module with deep linking. Here's what a typical handler class structure looks like:

import UIKit\nimport UserNotifications\n\nfinal class PushNotificationHandler: NSObject, UNUserNotificationCenterDelegate {\n    \n    func userNotificationCenter(\n        _ center: UNUserNotificationCenter,\n        didReceive response: UNNotificationResponse,\n        withCompletionHandler completionHandler: @escaping () -> Void\n    ) {\n        let userInfo = response.notification.request.content.userInfo\n        \n        guard let deepLink = DeepLinkParser.parse(userInfo) else {\n            completionHandler()\n            return\n        }\n        \n        Task { @MainActor in\n            Coordinator.shared.handle(deepLink)\n        }\n        \n        completionHandler()\n    }\n    \n    func userNotificationCenter(\n        _ center: UNUserNotificationCenter,\n        willPresent notification: UNNotification,\n        withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void\n    ) {\n        completionHandler([.banner, .sound, .badge])\n    }\n}

Notice Task { @MainActor in } — this is a modern way to force execution on the main thread without the old-fashioned DispatchQueue.main.async. An iOS developer now actively uses Concurrency from Swift 5.5+.

11:00 — Code Review: A Fresh Perspective

A notification arrives from a colleague: "Please review the PR." I open GitHub and see changes in the data model. Here's an example of what I often comment on:

// ❌ Bad: force unwrap\nlet user = users.first!\n\n// ✅ Good: safe unwrapping\nguard let user = users.first else {\n    assertionFailure("The users list should not be empty at this stage")\n    return\n}

During code review, we discuss not only correctness but also architecture. Today, a colleague used SwiftUI with @ObservableObject, but according to our code style, we are transitioning to @Observable (iOS 17+). I make a gentle note:

// We recommend rewriting with @Observable\n@Observable\nfinal class ProfileViewModel {\n    var name: String = ""\n    var age: Int = 0\n}

12:30 — Lunch and Context Switching

Lunch is sacred. I go outside or cook for myself. I try not to look at the screen — my eyes rest. During lunch, I often read Telegram
