Combining .searchable, .toolbar, and .navigationTitle on the same List triggered "Update ToolbarReader tried to update multiple times per frame" every time the sheet's first presentation animated in. Moving .searchable onto the NavigationStack instead — separate from the .toolbar/.navigationTitle chain on the List — avoids it. Reproduced and confirmed fixed via the unified log (Console shows the same warning under com.apple.SwiftUI:Invalid Configuration); the sheet, search field, and currency list all still render correctly.
