How to Successfully Retrieve Dates from Message Kit in Swift Firebase

If you're working with Message Kit in your iOS app and are encountering errors while trying to extract dates, you're not alone. This is a common hurdle developers face, especially when dealing with message structures and formatting dates from Firebase data. In this guide, we'll explore how to resolve these issues and ensure your date handling is robust and functional.

The Problem

You might be using a computed property getFormatter to format the dates, but this is where the confusion often lies. The goal is to convert date strings from your Firebase database into Date objects that can be properly utilized in your message structures. Unfortunately, your current setup is leading to a non-function type 'String' error, indicating that something is amiss in your implementation. Let's delve deeper into the solution.

Understanding the Issue

Your current getFormatter property looks like this:

Why the Error Occurs

The computed property getFormatter returns a String representing the current date, rather than a DateFormatter instance.

When you try to access this property in your network class using ChatDashboard.getFormatter(from: dateString), it results in an error because you're trying to treat a string as a method.

The Solution

To fix this problem, you need to modify your computed property to return a DateFormatter instead of a String. Here’s how to adjust your code:

Step 1: Update the Formatter Property

Rename and redefine your property to return a DateFormatter:

Step 2: Convert the Date String to a Date Object

Once you have the updated formatter, you can access it as follows in your getAllMessagesForConversation function:

Conclusion

By following these modifications, you'll not only eliminate the errors you're currently facing but also streamline your date handling in your message application. Remember, effective formatting and understanding how to manipulate Date and String types are essential for creating smooth, user-friendly chat experiences. Happy coding!
