Released a small update for Modulbank Informer. Updated the status bar icon (now more recognizable) and added a checkbox to hide accounts with zero balance. Plus, some minor refactoring.

TextEditor in SwiftUI still doesn’t have any API to get user selection. But since it’s using NSTextView internally we can subscribe to its notifications.

Here’s an example of getting a substring from user selection:

Before macOS 15:

import SwiftUI

struct ContentView: View {
    @State var myString = "Hello world"
    @State var selectedString = ""

    var body: some View {
        HStack {
            Text("Selection:")
                .foregroundStyle(.secondary)
            Text("\"\(selectedString)\"")
        }.padding()

        TextEditor(text: $myString)
            .font(.title)
            .onReceive(NotificationCenter.default.publisher(
                for: NSTextView.didChangeSelectionNotification
            ), perform: { notification in
                guard let textView = notification.object as? NSTextView else { return }

                // check, if it's the one we need
                guard textView.string == myString else { return }

                let selectionRage = textView.selectedRange()

                let start = String.Index(
                    utf16Offset: selectionRage.lowerBound, in: myString
                )
                let end = String.Index(
                    utf16Offset: selectionRage.upperBound, in: myString
                )
                let subStringRange: Range<String.Index> = start..<end

                selectedString = String(myString[subStringRange])
        })
    }
}

On macOS 15+ there's a new TextSelection struct which can be used in .onChange subscriber:

import SwiftUI

struct ContentView: View {
    @State var myString = "Hello world"
    @State var selectedString = ""
    @State private var selection: TextSelection?

    var body: some View {
        HStack {
            Text("Selection:")
                .foregroundStyle(.secondary)
            Text("\"\(selectedString)\"")
        }.padding()

        TextEditor(text: $myString, selection: $selection)
            .font(.title)
            .onChange(of: selection) {
                if let selection = selection.take() {
                    if case let .selection(range) = selection.indices {
                        selectedString = String(myString[range])
                    }
                }
            }
    }
}

Recently, there have been a couple of new releases for my Swift CouchDB library. Here are the recent changes:

• dateDecodingStrategy and dateEncodingStrategy can now be passed as parameters for get, update and insert methods.
• Added a check to handle expired authentication cookies.
• Comparing the set-cookie header in the response as lowercased.
• Introduced new methods to utilize the _find API, allowing you to find documents using a declarative JSON querying syntax
• Fixed an issue where the update method didn’t use dateEncodingStrategy parameter.

I’ve updated AppMetric for macOS — a client for Yandex’s AppMetrica service. The previous version, sadly, stopped working when they changed their response format.

From what I’ve been able to figure out, I was using something undocumented in their response. And judging by the current API responses, that was the number of crashes. Unfortunately, I had to remove it and replace it with the number of devices.

Since I finally got my hands on it, I decided to bring it up to date. Reworked everything in SwiftUI, but had to wrap the popup itself in good old NSPopover, because MenuBarExtra from SwiftUI is far too limited. Maybe I’ll get around to writing a separate post about it. While I was at it, I migrated everything to Swift Concurrency and SF Symbols. The catch is that it now requires macOS 13+, but I assume the people who find it useful keep their Macs up to date too. And, of course, finally — native Apple Silicon support.

The update went through review today and is available for download. In the future I’d like to add per-day/per-week charts.

Spotted an annoying bug in Modulbank Informer — if there was an account in Turkish lira, the JSON failed to parse and no data was shown at all. Fixed in this update.

Recently I noticed that Modulbank, the bank I use, has a public API. Since they don’t have a macOS app, and their iOS app doesn’t run on Apple Silicon (a security restriction on their side), I built a small informer that shows the list of accounts and balances in the status bar.

The app requires macOS 13+ — I wanted to squeeze the latest features out of SwiftUI and get some practice while I was at it.

Just a small update for Swift CouchDB client lib with couple new methods that I needed by myself:

• Added a new method to create a database [docs].
• Added a new method to delete a database [docs].
• Added a new method to check if a database exists [docs].
• Every request handles unauthorised errors now.
• CouchDBClientError model has a description text now.
