Example of how to use tableView(_:heightForRowAt:) to adjust the height of a UITableViewCell

heightForRowAtIndexPath.swift

//  The table views in this app actually don't make use of tableView(_:heightForRowAt:). These table views set the table views' 
//  rowHeight and estimatedRowHeight properties to UITableViewAutomaticDimension and 110, respectively, and they make use 
//  of a series of constraints to automatically set each cells' row height. 

//  Use tableView(_:heightForRowAt:) to set the height for specific table view cells.

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
//  Set the row height for the first (zeroth) cell in all section(s) to 100, and set all other cells to 50.
//  You can also set the row height for all cells in a section by accessing indexPath.section.
    if indexPath.row == 0 {
        return 100
    }
    
    return 50
    
}
