Background Timer App in SwiftUI & iOS

Are you an iOS developer looking to implement background timers in your SwiftUI app? Apple's background execution policies can make it challenging to keep a timer running when the app is minimized or the screen is locked. This course will guide you through building a fully functional background timer that works seamlessly within iOS constraints.

In this course, you’ll learn how timers behave in the foreground and background, explore iOS’s background execution limits, and implement practical solutions to ensure your app stays responsive. You’ll also discover state management techniques using @State, @Published, and Combine, allowing for smooth real-time updates.

We will start by building a basic timer in SwiftUI and then enhance it to work in the background using background tasks, notifications, and system optimizations. By the end of this course, you will have a solid understanding of how to create a power-efficient, user-friendly timer app that meets Apple’s best practices.

What You’ll Learn:

How to create a timer that continues running even when the app is in the background.
Understanding background execution policies and their impact on timers.
Managing state efficiently using SwiftUI property wrappers and Combine.
Using local notifications to keep users informed when the app is inactive.
Optimizing the timer to be battery-efficient and reliable.

Who Is This Course For?

This course is designed for iOS developers and SwiftUI learners who want to build apps with persistent timers while ensuring smooth performance and compliance with Apple’s background execution policies.

By the end of this course, you’ll have a fully functional background timer app ready to be integrated into your iOS projects. Let’s get started!
