how to create a table with dynamic cell height in swift

To create a table with dynamic cell height in Swift, we can use the following steps:

1. Set up a UITableView in your view controller and assign a custom UITableViewCell class to it.
2. In the custom cell class, add all the labels and UI elements that you want to display in the cell, and ensure that the constraints are set up properly so that the elements resize and reposition correctly as the cell size changes.
3. Implement the UITableViewDelegate method heightForRowAt in your view controller to return the dynamic cell height. This method calculates the size required for the cell based on its content, and returns the calculated height. For example:

main.swift
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableView.automaticDimension
}
144 chars
4 lines

4. In the same view controller, also implement the UITableViewDelegate method estimatedHeightForRowAt to provide an estimated height for the cells. This helps improve the performance of the table view by allowing it to more efficiently render the cells on screen. For example:

main.swift
override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return 80 // Provide an estimated height for the cells
}
170 chars
4 lines

With these steps, you should now have a dynamic table view that can resize its cells based on their content.
