notes from a developer, tutorials, how-to, ideas
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.

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:

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:

Every time you upload a screenshot on the App Store for a new app submission, you receive from Apple this error message:
Continue reading “Remove alpha channel from png images”“Images can’t contain alpha channels or transparencies.”
I want to introduce you to the new “App Icon Maker“, a simple and free utility for macOS that helps you to convert the images in the 3 Apple formats, @1x, @2x, and @3x.
PrivateFrameworks are always a joy.
Today, for a personal project I discovered how to use private Login.framework to lock programmatically via code (Swift or C) the screen of my mac book.

A simple tutorial for find and identify the wrong typed words of the user in your application using the UITextChecker framework and the NatualLanguage framework.
Very often you create a new class or a new view controller and customize it before start coding.
Every time you select from XCode, New File, the file type and add it to your project, like this:

My need was to control the robot asking simple commands through Google Home and Alexa like: “Alexa, clean the bathroom“.
With my robot, this was not possible. With the app, you can configure the zones but you can’t simply ask for cleaning only one zone, two times, for instance, all in automatic.

In my personal case I use three different git services for store / share my personal / work code:
Every service uses different SSH keys to use. Must be configured separately.
