Google’s Material You will probably be stable for pixel phones really soon. Seems like product teams at google are working hard on redesigning the google apps like Google Photos, Meet, Drive, Gmail and Calender to fit into Material You design guidelines.

As spotted by Google Pixels (Telegram) the Google photos app got the redesign recently.

In this article, we’ll get familiar with Xcode IDE. Things like where you can download it, how to start a new project in XCode, major parts of the Xcode interface, and your project file system.

Where do I find XCode ?

Let’s start by finding the xcode. Just launch mac appstore on your computer and search for Xcode, you should find it on the first result (if you’re lazy like me, just click here).

Hello, in this 10 article series, my goal is to help you familiarise yourself with building applications for iOS using the latest tools offered by apple.

In this series of articles, you’re going to learn about

  • How apps are made and end up on AppStore
  • How to use XCode IDE
  • How to build User Interfaces using SwiftUI
  • You’ll learn Swift Programming Basics

By the end of this series, you should be able to develop a fully functional mobile app, that you can install on your device and show it to your friends and family what you’ve done.

Credits: Myself

In this series of articles, I’ll help you integrate firebase into your flutter app to make it production-ready.

In this particular part, we’ll set up the new flutter project and connect it to a firebase project, set up everything for both android and iOS.

Adding the dependencies

Let’s start by adding the firebase dependencies to pubspec.yaml file. Scroll down to the dependencies section.

Note: Add these to the “dependencies” section, not the “dev-dependencies”. Learn about the difference here.

firebase_core: "^1.2.1"
firebase_analytics: "^8.1.1"

The first dependency is the core firebase dependency and I’ve included the…

I’ll try to explain this with an example so that you can easily understand when to use this method of authentication when building your application.

Role-Based User Authorization: Where users can have many roles and those roles provide different privileges that enable different operations on your (Firestore) database.

To better understand this, let’s take a look at the following data model.

As you’re just getting started with building android apps and I assume that you’ve set up everything like setting up the Android Studio IDE, downloading the SDKs and creating a brand new project. You can find a lot of tutorials and videos on how to do these boring things on the internet, let me skip that part.

Now, that you have a brand new android studio project, let’s start exploring the IDE a bit. On the left side of the IDE, you should see something like

Let me assume you’re an Android user, do you know that once you’ve allowed a third-party application the CAMERA and MIC permission they can potentially hear or watch you in the background? Yes, It can do it.

You probably might have heard about the iOS 14’s privacy feature which shows a little dot indication when an application uses your device camera or microphone.

iOS14 Indicator

This feature made me excited and I started to find a way to implement this on my Android device too.

As the result, I successfully mimicked this feature to android with my app called SafeDot.

This app…

Recommendation Systems | ML

Recommendation systems are pretty common these days. Netflix, Prime Video, YouTube and other streaming platforms use these recommendation systems to suggest a movie that you might like to watch according to your previous watch history.

Hearing this for the first time, got me excited. I started researching and building a simple prototype of a movie recommendation algorithm. I’ll walk you thought what I learnt from my research and building a working engine.

We’ll also build a system in python using scikit-learn python package. …
