And you need to randomly move between all these various server URLs for the testing purpose or maybe another Continue Reading »
MultiThreading – Multithreading means multiple tasks at the same time and the tasks which are being executed on what are Threads. Or we can say – In our app when we try to execute multiple tasks at the same time then our app UI will freeze because our mobile-only has 1 CPU. So we can Continue Reading »

Most of you would be familiar with Firebase integration in your apps, Firebase helps developers by producing human-readable crash reports. But sometimes, this fails due to dSYM files uploading failure. Debug Symbol files (dSYM) files are required by Firebase Crashlytics to give the app developers a human-readable crash report on its console. These dSYM files Continue Reading »
Ques: Why we use the Dynamic link? Ans: We use Firebase Dynamic links instead of Deep Link Because there is a limitation in the deep link that is when we click on an url & if we have not installed that app then the link is not working, in other words, it is only working Continue Reading »
Memory Safety in Swift Swift monitors risky behaviour that may occur in the code. For example, Swift ensures that variables are introduced before they’re utilized, likewise, memory isn’t accessed once its deallocated, and array indices are checked for out-of-bounds errors. Swift additionally guarantees that multiple access to a similar region of memory doesn’t conflict, Continue Reading »
Why Offline handling? Offline data handling in iOS apps isn’t an extra feature anymore. Users want and expect it as a default feature in apps. So it is necessary to save data in our apps. Data from researches and surveys show that users abandon pages if they take more than 3 seconds to load. This Continue Reading »
Q= What is multithreading? Multithreading is the most important concept, every developer must know about them. When we try to execute multiple tasks at the same time then our Ui get stuck and wait for another task to be completed. Because our iPhone has only one CPU and it can perform only one operation at Continue Reading »

Generics are simple yet one of the most powerful features of Swift programming language. Generic code enables us to write flexible and reusable functions that can work with any data type. Most of the Swift standard library is written using generics code. We have been using generic in our projects for a long time without Continue Reading »
A common scenario in application development is to have different environments, such as Debug, QA, Production… can be resolve via Multiple Firebase Environments. Requirement of having Multiple Firebase Environments : While your app is in development mode, or while it is being tested by the QA department, some “data pollution” could reach Firebase servers. Imagine your application is going to use Firebase Continue Reading »
Introduction: Memory management is a key factor when we developing apps. If a program is using a lot of memory it can affect badly on your device making apps run slowly or even cause crashes. So for that in swift, you can work with Automatic Reference Counting (ARC) to keep your apps memory usage minimal. This Continue Reading »
Introduction: Nowadays, Firebase Crashlytics is a very important part of our projects to monitor crashes of our applications that may be an android or iOS application. For the time being it is an unbeatable tool to log your day to day crashes for each user of your application. It provides good documentation and step by Continue Reading »

1. Lets list things we need to discuss:- Set our goal clear. Understand value of feature for End-User. Keep a track of all the test scenarios and new findings. After testing check have we covered all the checkpoints. UI checkpoints. Last but not least, give app/web_app to another tester who is not a part for Continue Reading »
Firebase Authentication in iOS When You want to create a user based app where you want to feature or activity depends on Users. I can assume, you need User Login, Forget password and Registration screen for user-related interactions. In most of the cases, Login/Registration User functionality doesn’t belong to Client end (i.e. iOS or Continue Reading »
Local Authentication in iOS In a Nutshell, Local Authentication in iOS is a framework which we use to validate genuine user through passphrase (i.e. passcode) or TouchID.

Dependency Inversion Principle Previous Principle: Interface Segregation Principle High-level modules should not depend on low-level modules. Both should depend on abstractions. When designing a system we have low level classes (classes which implement primary operation like: Network access, Disk access, Database access) and high level classes which have business logic. High level classes are dependent on Continue Reading »
Interface Segregation Principle Previous Principle: Liskov’s Substitution Principle A client should never be forced to implement an interface that it doesn’t use or clients shouldn’t be forced to depend on methods they do not use. In OOD we provide abstraction to module using interfaces, so we create an interface for a module and an implementation class. Continue Reading »
Liskov’s Substitution Principle Previous Principle: Open Close Principle Let q(x) be a property provable about objects of x of type T. Then q(y) should be provable for objects y of type S where S is a subtype of T. All it is saying that, Any method which is using a reference of base class can use Continue Reading »
Open Close Principle If you have not read Single Responsibility Principle Start from here Single Responsibility Principle Classes should be open for extension, but closed for modification This principle states that any new functionality can be added in a system with minimum modification in the current code. Means the system should be open to additions but it should Continue Reading »
Object Oriented Design Principles A good design is most important step of Software Development life cycle, and to have a good design we must follow some set of guidelines. According to Robert Martin in “Agile Software Development: Principles, Patterns, and Practices” there are 3 main reasons of bad design that should be avoided: Rigidity – System Continue Reading »
