Introduction
Parsing items into individual UICollectionView cells can be a great way to organize and display data in an efficient and visually appealing way. This tutorial will provide step-by-step instructions on how to parse items into individual UICollectionView cells. We will cover topics such as setting up the UICollectionView, creating custom cells, and populating the cells with data. By the end of this tutorial, you will have a better understanding of how to parse items into individual UICollectionView cells.
Solution
You can parse each item into its own UICollectionViewCell by using the UICollectionViewDataSource methods. Specifically, you can use the cellForItemAtIndexPath method to create a UICollectionViewCell for each item in your data source. In this method, you can create a UICollectionViewCell for each item and configure it with the data from the item.
For example, if you have an array of strings, you can create a UICollectionViewCell for each string and set the cell’s label to the string.
You can also use the numberOfItemsInSection method to determine how many items you need to create UICollectionViewCells for.
Finally, you can use the didSelectItemAtIndexPath method to handle user interactions with the UICollectionViewCells.

solved How can I parse each items into it’s on uicollection view cell
If you want to parse each item into its own UICollectionViewCell, you will need to create a custom UICollectionViewCell subclass. This subclass should contain the properties and methods necessary to parse the item into the cell. You can then use the UICollectionViewDataSource methods to populate the cells with the items.
To create the custom UICollectionViewCell subclass, you will need to create a new class in your project. This class should inherit from UICollectionViewCell and should contain the properties and methods necessary to parse the item into the cell. For example, you may need to create a method to parse the item into the cell’s UI elements, such as labels, images, and buttons.
Once you have created the custom UICollectionViewCell subclass, you can use the UICollectionViewDataSource methods to populate the cells with the items. The UICollectionViewDataSource methods provide the necessary information to populate the cells with the items. For example, the cellForItemAtIndexPath: method provides the necessary information to create the cell and populate it with the item.
Once you have populated the cells with the items, you can use the UICollectionViewDelegate methods to handle user interactions with the cells. For example, the didSelectItemAtIndexPath: method provides the necessary information to handle user interactions with the cell.
By creating a custom UICollectionViewCell subclass and using the UICollectionViewDataSource and UICollectionViewDelegate methods, you can parse each item into its own UICollectionViewCell. This will allow you to create a more customized and interactive user experience.
