What are the advantages and disadvantages of using Default DataSource in an application?

The default DataSource in an iOS application usually refers to the data source used by default for displaying information, for example, in a UITableView or UICollectionView.

Advantages:

• Simplifies architecture as there is no need to explicitly specify the data source everywhere.
• Allows quick setup of basic behavior of the interface.
• Suitable for simple applications or prototypes.

Disadvantages:

• Less flexible when different data sources are needed.
• Can lead to confusion if multiple components use the same default data source.
• Harder to scale and maintain as logic becomes more complex.

In summary, using a default data source is convenient for simple cases, but in more complex applications, it is better to explicitly manage data sources for better readability and maintainability.
