Why Start-ups Prefer Swift Over Objective-C

Why Start-ups Prefer Swift Over Objective-C
iOS App Development
If you are willing to develop a futuristic iOS app for your target audience, then Swift should be your preferred choice. This is so because Swift iOS app development is cost-effective and requires less coding efforts as the language is intuitive, easier to learn, and comes with several advanced features and powerful tools. This modern programming language is going to survive for long due to the plethora of benefits that it offers, as compared to its old competitor, Objective-C.
Earlier, Objective-C was principally used for building iOS applications. However, it became out-dated slowly due to the lack of several useful features offered by other new-age programming languages. Apple Corp had worked on Objective-C improvements for almost 6 years and understood that a better language could be introduced for writing mobile applications. Due to such loopholes of Objective-C, Apple introduced an advanced language in 2014- Swift which had pioneering features to accelerate the iOS app development.
Swift is general-purpose, multi-paradigm, and compiled language. It is a fast, safe, and interactive language specially developed for iOS, macOS, Linux, tvOS, and watchOS. It soon superseded Objective-C and became the favorite of developers across the world. Several giants like LinkedIn, IBM, Facebook, Mozilla, Uber, etc. were already using Swift but now, even start-ups have started focussing on it.
In this blog, we will explore the key reasons why start-ups choose Swift for iOS app development instead of Objective-C.

Top Reasons why Start-ups Prefer Swift over Objective-C

Swift app development services
Swift is quite successful today not only because it is feature-rich and well-structured, but also due to a huge support of millions of people, globally. Its independently managed conferences enhance the Swift community. Also, there are two main differences between Swift and Objective-C:
  • Swift isn’t a superset of C, so, it can freely make use of syntax constructs. This enables implementation of custom operators.
  • Swift is not dynamically typed but it is statically typed, due to which it can take benefit of a number of recent advancements in the type systems.
Let us understand in detail about what more is there for start-ups to prefer Swift over Objective-C.

Open-Source and Fast-Growing Language

Swift is the fastest-growing open-source language and has great potential. It can be immediately accessible to anyone and start-ups can take advantage of this. Also, Swift can be applied across several platforms and backend infrastructure as well since it is open-source. It is also available on Linux and efforts are being made to bring it to Windows. Swift receives feedback from the iOS app development community to make improvements to get more structured. Comparatively, Objective-C isn’t an open-source language and also becoming out-dated gradually.

Less Coding Efforts and Less Prone to Errors

Swift is a functional programming language and allows passing functions as variables. It also allows manipulation of data and text strings. This lets the Swift developers develop generic code which reduces the coding efforts to a great extent. So, writing, reading, and modifying the code is easier in Swift which ensures better readability. Also, this language has smaller code lengths due to the use of a feature called- Type interface. This feature helps to avoid incorrect coding and provides less error-prone code.
When a null optional variable is used in Swift, a run-time crash is triggered instantaneously. Due to its consistent behavior, this crash forces the bug-fixing process and so, the bugs get fixed instantly. As a result, even the development time reduces.
However, in Objective-C, complete code needs to be written every time there is a change in the code. So, it needs extensive coding and has greater execution time.

Shorter Time-to-Market

Shorter time-to-market is a critical factor for start-ups. What they want is good-quality products in less time. Of course, they need to hire dedicated iOS app developers for this. But in addition, Swift has package managers that allow the developers to focus on the logic, push their packages for collaboration with others, and use different packages for quickly assembling the applications while significantly reducing the time-to-market.
Similarly, there are many other speed-based advantages that Swift offers over Objective-C apps while developing iOS apps due to which start-ups prefer Swift.

Highly Safe and Secure

Safety and security is a very important factor while developing mobile apps. Swift has an all-inclusive Security Framework having several APIs that handle authorization services, certificates, keys, trust policies, etc. Some APIs are also used to apply cryptography encryption to the messages. Also, as discussed earlier, the use of a nil optional variable makes the bug-fixing process easier and immediate.
Syntax in Swift forces the coders to write a clean and consistent code. It not only saves time but also supports the safety of the apps, though it may feel strict sometimes. The way Swift handles the bugs ensures safer applications as compared to Objective-C.

Needs less Maintenance

Swift for iOS app development is preferred by start-ups for one more significant reason. This programming language doesn’t have any legacy code and so, needs lesser maintenance as compared to Objective-C. Unlike Swift, Objective-C depends on C for its evolution. In C, iOS app developers need to maintain and manage two separate code files- (.h) header file and (.m) implementation file, for better efficiency and building time of the app. The same legacy is carried forward by Objective-C, which can be cumbersome to manage at times. In the case of Swift, only one single file- (.swift) needs to be maintained, making the overall maintenance quite easier.

Has a Bright Future

Swift is a well-designed and well-organized programming language. It provides an enhanced development process along with some excellent features which simplify the developers’ task.
Though Swift has emerged just a couple of years ago, yet it has made a tremendous evolution. Undoubtedly, Objective-C won’t vanish from the market but it has definitely started losing ground ever since Swift came into the picture. Also, it is evident from the conferences held by Apple and its software releases that Apple is going to develop Swift with some amazing features. So, we can expect several upgrades of Swift in iOS app development in the future.
Along with the above-mentioned points, there are a few more considerations for the start-ups to choose Swift over Objective-C, as listed in the below table:

ParadigmObject-OrientedClass based Object Oriented
PerformanceHigh-performanceNot fast-performing due to runtime code compilation
ComplexityRequires fewer code lines making it simplerCoding is complex as text strings need many steps for linking different pieces of information
Community supportA fast-growing community of supportersLoyal community for 30 years
Memory managementSupports the ARC for all APIsUses the ARC supported only within the Cocoa API
Long-term OutlookRapidly growing and has a bright futureConstant support by Apple
Dynamic libraries supportSupports dynamic librariesDoesn’t support dynamic libraries
ReadabilityClean syntax and better readabilityUses many @ symbols, semicolons, lines, etc. to insert new keywords and making it difficult to read

Key Takeaways:

Swift and Objective-C are the two most high-end Apple programming languages. However, Swift supersedes Objective-C in many ways. It is clean, expressive, and intuitive as compared to Objective-C. Also, when it comes to cost-savings, developing a Swift app for your business is the apt choice. So, in this competitive business world, it is advisable for start-ups to opt for Swift and hire Swift app developers for building powerful, immersive, and profitable iOS applications.

Microservices vs Monolithic Architecture: Which Approach is Suitable for a Start Up?

Microservices vs Monolithic Architecture: Which Approach is Suitable for a Start Up?

Monolithic Architecture is a traditional approach in which the entire app is integrated into a single unified model. The prime objective is to interconnect all features making them co-dependent on each other. This model may sound simple, but creates roadblocks in handling bigger and more complex projects.
Microservices architecture, on the other hand, splits an app into smaller services that are interconnected and interact with each other with the help of APIs. Every microservice is independent, loosely coupled, and possesses a distinct hexagonal architecture comprising of business logic and different adapters. Here, each service is a separate codebase, has its own database, and can be deployed independently. This approach has gained momentum these days as modern-day businesses expect more agility in their operations. Some renowned brands using the microservices approach are Uber, Twitter, AWS, Netflix, and Spotify.
This post explores Monolithic and Microservices architecture in detail, outlines their differences and provides suggestions based on specific project requirements. A quick read will help you to pick the best-suited approach for your upcoming software development project.

Monolithic Architecture: Strengths & Weaknesses

Monolithic apps perform speedily at the initial stages as they use local calls in place of API calls throughout the entire network. But, this speed reduces with the expansion of the app. A monolithic app, being a single solution, rather than a set of separate apps, is easily manageable, involve much lower development cost, and encounter very few cross-cutting issues initially.
When the codebase of a monolithic app becomes huge, the IDE slows down, adversely affecting the developers’ productivity. Moreover, it’s challenging to scale the app, and modifying the programming language or framework that hampers the app’s functioning. Also, it’s pretty expensive to migrate to different technology in situations where monolithic architecture is used.

Microservices Architecture: Strengths & Weaknesses

Microservice architectures are well organized – each microservice is responsible for carrying out a particular task, without being concerned about the tasks carried out by the other components. And, since such services are decoupled, they can be effortlessly reconfigured and recomposed to fulfill the needs of various microservice applications. For instance, microservices can serve public API as well as web clients.
Each microservice can be written employing a different technology; for instance, one microservice can be handled by Java developers while the other can involve DotNet developers. Thus, you have the flexibility to choose a particular technology for catering to specific business requirements without having to lock other services with that technology. This helps in optimizing the performance of crucial functions.
Microservices allows you to auto-scale an application as per the load on the app, promises speedier deployment, and eases out rolling updates as there aren’t any dependencies between the services. With this type of architecture, you can execute parallel development by setting up boundaries between various parts of the system; these boundaries are difficult to violate resulting in fewer errors.
Microservices apps consume more memory; involve higher development costs initially; come with complex requirements regarding the operation, testing, deployment, and management; and need a greater level of developmental proficiency and expertise.

Microservices vs Monolithic Architecture: Comparison

Here are some major differences between Microservices and Monolithic architecture based on these crucial parameters.
In Monolithic architecture, the app’s UI, database, business logic, front-end, and back-end are integrated into a single codebase; whereas in microservices architecture, all the aforesaid app elements are subdivided and operated independently of each other. Likewise, the processes of testing and deployment are executed under one line in monolithic apps, while in microservices apps, these processes are scattered across different adapters and databases.
Monolithic architecture is deployed in a traditional format and caters to standard web servers. For deploying microservices, on the other hand, a plethora of approaches are supported – One service-One host approach (each service is deployed to one virtual host machine); One Service-One Container approach (microservices are isolated by docker containers, but resources like frameworks, libraries, and operating servers are shared); and Serverless deployment (third-party cloud services host and manage the servers on which the program runs).
Developing a monolithic application is easy if the app is new, but as the app gets bigger developmental challenges crop up. This is because the huge indivisible database needs the joint effort of the development team.
Microservices, on the other hand, offer loose coupling and several options to choose from while picking the tech stack; but the app developers must possess a more profiled knowledge. However, this structure allows developers to work independently on each component.
Testing is pretty simple in a monolithic app as a single script is used for testing the whole system while testing a microservices application becomes complex as every part of the app needs to be tested separately.
Microservices architecture enables continual development and deployment as every service gets individually implemented. With monolithic architecture, deployment becomes slower.
App Updation
The process of updating a microservices application happens uninterruptedly and doesn’t slow down the entire system. Contrarily, updating a monolithic app is voluminous and burdensome and for every update, the entire app has to be redeployed.
The bigger the monolithic app the more challenging it becomes to scale the app – for handling new changes the entire system has to be redeployed. In microservices apps, each part is scaled independently without downtime and so, involves fewer hassles while carrying out modifications.
Security and Reliability
Monolithic architecture involves a single source code; communication happens within a single unit, resulting in secure data processing and a simple monitoring procedure. Microservices architecture, contrarily, involves inter processing between multiple API connections increasing security threats, and hence, greater security monitoring is needed. However, in monolithic apps, one bug can hamper the whole system, while in microservices apps, one bug affects only that specific service and the bug can be topically fixed. Therefore, even when one service fails other services are not affected.

When should you pick Monolithic Approach?

You intend to develop a Simple App with faster Time-to-market
Monolithic architecture is an ideal choice for building a simple app that doesn’t require reinventing the wheel and the app is unlikely to scale rapidly. Moreover, developing the prototype of a simple app will take place at a fast pace leading to quicker time-to-market.
Smaller-sized Team and No prior Experience with Microservices
Start-ups with smaller-sized teams will benefit from the monolithic approach as experience and expertise in one tech stack will suffice and your team will not have to handle any developmental complexities. Furthermore, if your team doesn’t have any prior experience of working with microservices, picking this approach will be a risky business. In such a scenario, it’s better to start with a monolithic approach and migrate to microservices later on as and when needed.
Your app idea is Novel, Unproven, or the Proof of a Concept
If you have a novel app idea or planning to create a product that is unproven, your application is likely to evolve with time. Here, a monolithic approach will help in iterating the product speedily. Similarly, if your intended app is all set to prove a particular concept, you need to learn more within a short time and monolithic architecture will prove beneficial.

When should you pick Microservices Approach?

Your app is Complex and needs unprecedented Scaling
If you wish to develop a complicated software solution that involves a rich feature set, a substantial amount of personalization, extensive use of interactivity, a huge amount of business logic, or needs to be run by various modules; microservices architecture is your ideal pick. Start-ups who plan to build a highly innovative and revolutionary app that targets a humongous audience base and comes with heavy scaling requirements are recommended to adopt the microservices approach.
Need for Isolated Service Delivery
Microservices work better if you need to deliver independent services speedily. However, for this, you need a sufficient amount of resources as well.
A part of your Platform needs High Efficiency
For instance, your business is intensively processing petabytes of log volume. In such a scenario, you’ll have to create a service with a super-efficient programming language like C++ whereas the users’ dashboard can be created in Ruby on Rails.
Effortless Team Extension
If you commence your start-up with microservices architecture, your team will get accustomed to the idea of developing small services right from the very beginning and the teams will be segregated by service boundaries. So, later on, you can effortlessly scale up your team as per the need.

When is it advisable to migrate to Microservices Architecture?

It’s time to migrate to microservices architecture when your monolithic app grows big enough to create maintainability issues, when your business functions and their boundaries are crystal clear enough to be converted into individual services, and when your app needs scaling to deal with a humongous user load.
Example: The popular app Netflix started as a monolithic application. With time, the app experienced a surge in the demand leading to issues concerning performance and reliability. As such, the owners migrated their app to the cloud-based microservices architecture. Consequently, the app got segregated into hundreds of microservices and this approach enabled boundless expansion and scaling.

Summing Up:

Monolithic architecture as well as microservices architecture comes with its own set of strengths and challenges. So, when deciding on the most suitable pick for your start-up, you need to first define the requirements of your software development project. If you plan to develop a lightweight app and have budgetary constraints, it’s advisable to go with the monolithic approach. But, if your project is huge with complex requirements or you need to work with futuristic models like Big data, and you can spend on hiring several cross-functional teams, microservices is the most viable option.
