Last active January 18, 2024 12:13
Use a SwiftUI View as inputAccessoryView, dynamically adjusting to height changes
// (c) Hannes Oud @hannesoid
/// Hosts a SwiftUI view for use as an`inputAccessoryView`
///
/// - Implements a subclass of `UIInputViewController`, this allows setting it as `UITextView.inputAccessoryViewController`
/// - Has as a `.view` a `UIView` subclass that provides a `.intrinsicContentSize` which returns the height of a SwiftUI view
/// - Has a `UIHostingViewController` subclass as a child view controller. Invalidates the `.view`'s `intrinsicContentSize` when the SwiftUI view layouts, in order to inform the system to update the size of the `inputAccessoryView`
///
/// **Usage**
///

iOS15 UITableView Duplicate Cell Usage Issue

This only happens on iOS 15 and only when building with Xcode 13. UITableView with (non-diffable) UITableViewDataSource and just one cell type.

Steps

The set up where the issues arises is, we have a row in which we are editing text, insert another after it, and want to continue editing in the new row.

  • [row 0] cell_0 with textView that is firstresponder

Then we call insertRows(at: [.init(row: 1, section:0)], with: …). Within UITableViewDataSource.tableView(…, cellForRowAt:) we correctly get tableView do dequeue a new instance cell_1. (side note: all cells have same reuseIdentifier). In the same tableView(…, cellForRowAt:) method we configure the cell's textView to become the new firstResponder.
