How to Locate a CSV File in iOS Simulator or iPhone Using Swift

When developing iOS applications, you might encounter scenarios where you need to manage data stored in CSV files. Whether it's for testing purposes in the iOS Simulator or for production on an actual iPhone, Swift provides a straightforward way to locate and handle these files using the FileManager class.

Using FileManager to Locate a CSV File

FileManager in Swift offers a range of functionalities to interact with the filesystem. Here's a step-by-step guide to locate a CSV file in your iOS application:
