Mastering Date Formats in Swift for iOS Development

When developing an iOS application, working with dates can be a bit tricky, especially when you need to convert dates into user-friendly formats. Have you ever wondered how to format a date like 1st July, 2021 17:00 in Swift? Whether you are displaying dates in your app or processing date inputs from users, understanding how to manipulate date formats is essential for any iOS developer. In this post, we will explore how to both display and convert this specific date format using Swift.

Displaying Dates in Custom Formats

Converting String Dates Back to Date Objects

Sometimes your application might need to convert a date formatted as a string (e.g., 1st July, 2021 17:00) back into a Date object. Here's how to achieve that:

1. Use the Input String

Start by defining the string representation of the date.
