Error handling in Swift

Error handling is crucial for application success, allowing users to navigate and utilize features effectively. This tutorial focuses on detecting and resolving errors in a Swift-based bookstore application, where users can purchase books using a wallet balance. It outlines setting up the project in Xcode, creating classes for users and items, and implementing a function to handle book purchases. The tutorial identifies potential errors such as insufficient wallet balance and inadequate book quantity, recommending the use of error conditions and custom Swift enums to address these issues. By incorporating the do-catch feature, developers can catch and handle specific errors, enhancing the app's reliability. The tutorial encourages defining custom errors to facilitate faster issue resolution and suggests using LogRocket for modern error tracking.
