The macOS status bar is a powerful and convenient place to display essential information or provide quick access to your app’s functionality. By default, the status bar displays a standard system icon, but sometimes you may want to create a more customized experience by using your own views. In this blog post, we’ll walk you through how to use a custom view on the status bar in macOS using Swift and SwiftUI.
Before we get started, make sure you have the following:Read More
In modern software development, data persistence plays a crucial role in preserving and accessing user preferences and app state across sessions. With the release of Swift 5.1, a new feature called property wrappers was introduced, which allows developers to encapsulate and automate common behaviors associated with property access. In this article, we will explore how property wrappers can simplify data persistence using a practical example.
Let’s consider a scenario where we want to persist various user settings in our app, such as the user’s name, preferred currency, color scheme, profile picture, and the ID of the latest order placed. We can leverage the power of property wrappers to achieve this in a concise and efficient manner.
Add a property wrapper
In this way we add a
@Storable property to use in your application.
The Internet of Things (IoT) is transforming the way we interact with the world around us. AWS offers a robust suite of services for developing and managing IoT solutions, including the AWS IoT SDK for iOS and Android. In this detailed article, we will explore how to effectively utilize the AWS IoT SDK to create a sample iOS application that leverages MQTT protocol for sending GPS locations.
To get started, you will need the following:
- An AWS account with access to AWS IoT resources.
- Basic knowledge of iOS development using the Swift programming language.
- Familiarity with Android development using either Java or Kotlin.
Step 1: AWS IoT Configuration:
Learn how to configure AWS IoT to establish a seamless connection between your devices and the cloud. Follow these steps:
resuming an old post, that help you to create an UIAlert extension to show a modal popup, https://www.albertopasca.it/whiletrue/objective-c-modal-view-in-navigation-and-tabbar-controller-projects/ , I’ve created a new modern implementation that use UIWindow.
The scope is to show a spinner (or a Lottie spinner, or whatever you prefer), centered in the screen with automatic or manually dismission. Background can be blurred or colored, like this screen:Read More
Weward is a mobile app that basically pay-you if you walk; offer also a price exchange and lots of offers inside the app.
The first time I opened it, I see at glance that I can hack it… and of course you can do it by yourself, very quick and easily. Let’s see how.Read More
This is my work in progress ~50cm Robotic Arm with 6 AXIS Servo motors, an Arduino and a RaspberryPi (for image recognition in phase 2):
While writing the C++ code in Arduino I found I needed a way to send easily and fast commands to Arduino with my iPhone using Bluetooth.
Basically I need to control my robotic arm using an external device instead of running and running again the code on the Arduino board.
For this reason: I’ve attached a BLE board to Arduino and I have created a simple app (completely written in SwiftUI 😍😎) that use BLE connection to connect to Arduino BLE board and send string commands that are parsed and executed.
Commands sended are like:Read More
Very often a lots of iOS applications use your gps position to retrieve data or to lock / unlock contents positions based.
With Android you can use lots of apps called Fake GPS or similar that allow you to change your real gps position with a mocked one.
On Android development side this can be blocked checking via code the:Read More
Today I want to share a simple way to retrieve user data from a native iOS cache image, automatically generated when your app goes in background.
You can retrieve this kind of informations if your phone was lost or Jailbreaked or connecting it to your pc and open an old backup. You can use tools like iBackup Viewer and more…
Let’s see how it works!Read More
Every time you upload a screenshot on the App Store for a new app submission, you receive from Apple this error message:
