This project demonstrates expanding and collapsing UITableView cells. There are many approaches to this but using a UIStackView is currently (Xcode 10, Swift 5) the one that best handles cells with unique heights and supports auto layout. There are so many details to get right that I collected them in this simple project, rather than searching Stack Overflow each time I implement. Details like pinning the UIStackView to the cell’s contentView , setting tableView.rowHeight = UITableView.automaticDimension, setting variable line height UILabels Content Compression Resistance Priority, etc. are easy to overlook and may not manifest issues till runtime.
