Autofill for links

[benlong100]

Hi, I'm using MarkupEditor in an app that edits HTML files that are stored locally on the device, in a CoreData store. In the add-link pop-up, I'd love to be able to trigger an additional pop-up window that would show autofill suggestions from the database. So, when creating a link in one entry, as you start to type the title of another entry, it would show a list of matching titles from the CoreData store. Any chance you could give me a rough idea of how to architect that?

In my app that consumes MarkupEditor, I override markupShowLinkPopover in my SwiftUI view that is the MarkupDelegate like this:

func markupShowLinkPopover(_ view: MarkupWKWebView) {
    linkPopupRect = MarkupEditor.selectionState.sourceRect
    showLinkEditor.toggle()
}

That view includes:

@State private var showLinkEditor: Bool = false
@State private var linkPopupRect: CGRect?

and then I use the MarkupEditor's forcePopover modifier inside that view:

.forcePopover(isPresented: $showLinkEditor, at: linkPopupRect) {
    LinkEditor(presented: $showLinkEditor)
}

The LinkEditor view has all my logic for custom presentation of creating/editing/deleting links, but includes the following:

struct LinkEditor: View {
    @Binding private var presented: Bool

    public init(presented: Binding<Bool>) {
        _presented = presented
    }

    // Lots of other stuff, including the body!

    private func dismiss() {
        presented = false
        MarkupEditor.showInsertPopover.type = nil    // TBH, not sure it's needed here
    }
}

The LinkEditor view methods like save and cancel all eventually invoke dismiss().
