问题 Is there a way to prevent cells in a tableView from being moved to a different section? The sections have data for different types of cells, so the app crashes when the user tries to drag a cell into a different section. I would like to only allow the user to move a cell inside the section, and not in between sections. Relevant code is below: override func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool { return true } override func tableView(_ tableView:

问题 I'm new to Realm and Swift, and to this site for that matter, so please forgive me if my question is poorly worded, but I will do my best. Here goes... Basically I'm trying to build a Gym App. The idea is to allow the user to type out the title of their workout and to select a day of the week from a Picker View, to assign to that particular workout.

问题 I'm implementing a search screen in my app using UITableViewDiffableDataSource . Each cell represents a search hit and highlights the search match in the cell title, kind of like Xcode's Open Quickly window highlights portions of its result items. As text is typed into the search field, I update the results list. Results move up and down in the list as their relevance changes. The trick is that I need to force every cell to re-render every time the search text changes, because a new search
