Version: Version 10.0.0.2397 (develop) built on bajor, 20190419-153353. Commit 6f2fbf4.
Target (If relevant): iOS
Description:
When I try to use a simple enum as defined here:
private struct FormSection {
var title: String?
var rows: [FormItem]
public init(title: String?, rows: [FormItem]) {
self.title = title
self.rows = rows
}
}
public enum FormItem {
case text(title: String?, details: String?)
case editable(text: String?, placeholder: String?)
}
and I then use FormSection and FormItem struct and enum by defining a list of items like this:
public override func viewDidLoad() {
super.viewDidLoad()
tableView.register(TextFieldCell.self, forCellReuseIdentifier: "TextFieldCell")
self.sections = [
FormSection(title: "Title", rows: [
FormItem.editable("Text", "Placeholder"),
FormItem.editable("Text", "Placeholder")
])
]
self.tableView.reloadData()
}
If I next try to use switch to determine which enum types is to return the appropriate table view cell like this:
private func tableView(_ tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell {
let row: FormItem = sections[indexPath.section].rows[indexPath.row]
switch row {
case .editable(let title, let placeholder):
let cell: TextFieldCell = tableView.dequeueReusableCell(identifier: "TextFieldCell", for: indexPath)
cell.textField.placeholder = "Placeholder"
cell.textField.text = "Title"
return cell! //UITableViewCell(style: .subtitle, reuseIdentifier: "Cell")
}
}
I am getting an internal error in the compiler:
Reference: /Applications/Fire.app/Contents/Resources/Toffee SDKs/iOS 12.2 Simulator/CoreFoundation.fx (implicit)
-> Phase Resolving Bodies started.

Expected Behavior:
The switch allows to destructure the enum and get the values title and placeholder of the .editable-enum type.
Actual Behavior:
An internal error is raised (see above) while I would expect the code to compile
