Auth on Firebase & Parse

Auth on Firebase & Parse

In Part 1 and Part 2 of this series, we compared the process of creating an App and integrating frameworks to your XCode project and how Firebase and Parse databases have similar and distinct features that might fit better to your use case.

In this third part, we will start coding and evaluate how much code is necessary to get a Sign-Up / Sign In process working on both platforms.


Firebase vs. Parse – A comprehensive comparison for iOS development in 2020 – Part 1

Firebase vs. Parse  – A comprehensive comparison for iOS development in 2020 – Part 1

Introduction

Parse and Firebase are platforms created to make the developer’s life easier, building the server-side of your application much faster, solid, and scalable.

Those two products hit the market a few years back and evolved since, always bringing new functionalities and keeping up with newer technologies.

The two take different approaches to how they do what they do. Also in how they support the iOS development specifically.

As an iOS developer myself, I decided to write a totally unbiased view of both platforms for the iOS world and see how they approach this market share specifically.


Web Data Scraping using Parse

Web Data Scraping using Parse

After we published our open database for Coronavirus COVID-19, which is based on Wikipedia’s data, some people started asking how we collected data in an automated fashion. This article will teach you how to write a data scraper (or data collector, data miner, etc) in Back4app using Cloud Code Functions that will automatically collect content from a given URL, filter the important data and store it in Parse.


How to Build a Video Chat App

How to Build a Video Chat App

Just the other day I came across this awesome Twilio tutorial by Phil Nash explaining how to make a Video Chat using React Hooks, so I decided to run it in Back4app because it is free, it is awesome and can be integrated with Parse, so I could have free web hosting (free back4app subdomain included), host my App and use real-time data delivery to include chat features in the future.
This post is a walkthrough of what I did to get it working.


GraphQL Queries and Mutations on distinct Parse Versions

GraphQL Queries and Mutations on distinct Parse Versions

As Parse evolves over time, some aspects of it change for better performance, better compatibility and easier development.
One of these aspects is the GraphQL support that evolved from Parse 3.5.0 over time to the latest version available, 3.9.

Here at Back4app, we have three main versions that implement changes in the GraphQL queries and mutations, specifically: 3.7.2, 3.8 and 3.9 and today I will walk you through the differences among those versions, showing what did change and what did not.


Um clone do Instagram usando SwiftUI e GraphQL

Um clone do Instagram usando SwiftUI e GraphQL

Hoje estamos iniciando uma série de postagens no blog que ensinarão você a usar muitas ferramentas interessantes para criar sua própria rede social: um aplicativo que se assemelha ao Instagram.

Não economizaremos tecnologia e usaremos o melhor e o mais recente: Parse, GraphQL, um pouco de NodeJS e especialmente o framework SwiftUI da Apple (ainda a ser lançado). 😍

Isso levará algumas postagens para ser totalmente funcional, mas quando chegarmos lá, você perceberá como pode ser simples colocar suas ideias em funcionamento com muito pouco esforço aqui no Back4App.

Então, parece que é hora de…

Uma breve introdução

Bem, você provavelmente já conhece os enormes benefícios que o Parse traz para o seu processo de desenvolvimento, especialmente se hospedado no Back4App, pois nosso conjunto de ferramentas aumenta a produtividade em grandes quantidades.

E nossas publicações mais recentes sobre o  GraphQL  mostraram como é fácil manter o desenvolvimento de APIs ao longo do tempo, se você o usar. Se você perdeu essas postagens, sugiro fortemente que você reserve um tempo e as leia, pois elas melhorarão muito seu entendimento à medida que avançamos.

Você pode ler mais sobre o GraphQL  aqui  e também temos um post completo sobre como usá-lo  aqui .

Você também pode ver alguma integração com o NodeJS em Cloud Code Functions  aqui .

Isso nos deixa com SwiftUI.

O SwiftUI é, de acordo com a Apple, “uma maneira inovadora e excepcionalmente simples de criar interfaces de usuário em todas as plataformas da Apple com o poder do Swift”.

Eu próprio gosto de pensar que o SwiftUI é mais do que isso.

Se você, como eu, está desenvolvendo software há algum tempo, provavelmente sabe que a comunidade de desenvolvedores sempre esteve dividida entre a conveniência de usar Storyboards, a interface de criação de UI de arrastar e soltar da Apple ou o poder da interface de usuário programática.

O SwiftUI vem para trazer o melhor dos dois mundos: é fácil o suficiente para os iniciantes aprenderem, enquanto mantém a capacidade de manutenção de uma interface do usuário codificada.

Combine isso com a renderização em tempo real, para que os desenvolvedores possam ver facilmente a saída visual do que eles estão codificando, e o façam de duas maneiras. Se você alterar o código, ele refletirá na interface do usuário e alterará graficamente a interface do usuário. no código, e o que você obtém é uma das maneiras mais poderosas e fáceis de fornecer interfaces de usuário com design bonito e manutenção ao longo do tempo.


Instagram Clone App using SwiftUI and GraphQL – HomeView

Instagram Clone App using SwiftUI and GraphQL – HomeView

Today in part 4 of our Instagram clone App with GraphQL we will continue learning some SwiftUI, building our Home view.

In our previous articles, we learned how to sign up a user and how to log in a user and created the Profile view with the respective UIs in our Instagram clone App. Today we will reuse some of that code and create something similar to a UIScrollView with lots of content.

Fast your seat belts and let’s get it going!

For better learning, download the iOS Instagram Clone project with source code.

Today in part 3 of our Instagram clone App with GraphQL we will get deeper into SwiftUI, building our Profile view.

We will learn to reuse structs in SwiftUI and discuss a few controls: VStack, HStack, GeometryReader, Text, Button, Spacer, Image, Divider among others.

In our previous articles, we learned how to sign up a user and how to log in a user, with the respective UIs in our Instagram clone App. Today we will make it much nicer.

Fast your seat belts and let’s get it going!

In our previous post about how to create an Instagram clone app, you learned how to configure everything to have SwiftUI up and running in XCode 11, and created a fully working Sing Up view with GraphQL.

Today we will learn how to create a login view and have the user log out.

We will be needing the project from the previous post, so if you didn’t follow that one, I strongly suggest that you do.

Buckle your seat belts and let’s go!

Today we are starting a series of blog posts that will teach you how to use a lot of cool tools to build your own Social Network: an application that resembles Instagram.

We won’t save up on tech and will be using the latest and greatest: Parse, GraphQL, some NodeJS and especially the (yet to be released) latest Apple’s framework SwiftUI. 

This will take a few posts in order to be fully functional, but when we get there, you will realize how simple it can be to get your ideas up and running with very little effort here at Back4app.

So, it seems it is time for…
