In iOS projects, I have sometimes needed to use an Accordion-style table view where only zero or one sections show their rows at a time and the rest are folded up until the section header is tapped. Using UIKit, I did this with a third-party library and many, many delegate methods.
This seemed like something that SwiftUI would do well, and it did.
- ContentView.swift contains all the layout.
- Company.swift is the data model.
- WebService.swift gets the online data
ContentView sets up a NavigationView with two alternative views depending on whether the data has been downloaded or not.
LoadingView is a very simple text display.
DepartmentList is the interesting view but the sections and subviews are well commented. It has a separate subview for each possible row type:
- DepartmentTableRowView to show the department names and act as the header
- PersonTableRowView to show the individual entries in each section
Both the row types are active becasue the content of each is enclosed in a Button.
The DepartmentTableRowView toggles the accordion display.
The PersonTableRowView toggles a hasSignedIn flag which will display a person icon if true.
I have not added a single animation command to this, it is all just standard animations.
- 28th August 2019:
- Removed web service for data, replaced with local data file for faster testing.
- Renamed subviews and separated out their tap actions for more general use.
