It's every CTO's worst nightmare: your developers are the lifeblood of your company. They manage our most valuable digital assets and without them, you can't launch or maintain any meaningful customer engagement plans. But what happens when one of these key members suddenly walks away from their post with little to no notice? Suddenly, you've got a critical hole in your product development team that needs to be filled – but fast! You must find a replacement quickly. But even then, there’s still the daunting task of ensuring continuity in launching and maintaining new products as well as existing applications already live on the market. In this blog post, we'll discuss ways to make sure your app stays up and running even if (or especially if!) a developer decides to move on swiftly leaving behind incomplete projects for whoever steps up next.



What is App Architecture and Why Does it Matter?



App architecture refers to the overall structure and design of an application, both from a technical perspective and a user experience perspective. This includes factors such as how the application is built, how it stores data, how users interact with it and more. App architecture is important because it affects the performance and scalability of an application. Poorly designed architecture can lead to slow loading times, user frustration, and system crashes. On the other hand, well-designed app architecture can help ensure that applications are fast, reliable, secure, and easy to use for users.

A key element of app architecture is the selection of an appropriate software framework or development environment for building the application. Software frameworks provide foundational components that can be used to quickly build out an application without having to start from scratch. Different frameworks are better suited for different types of applications so selecting the right one for your specific use case is important.

For example, many iOS developers jump to VIPER as an architectural pattern just because they read about it on Medium.

Using the VIPER architecture pattern in iOS development without good cause and thorough discussion among the team can be dangerous for many reasons. Firstly, the VIPER structure is comparatively more complex than other structures and requires a good understanding of each component's role to create a successful application. Without proper planning and knowledge of the components involved, mistakes can easily occur which may lead to serious bugs or flaws in the program's code. Additionally, VIPER is best suited to larger projects with multiple developers and can be overkill for smaller projects that don't require so many layers of abstraction. These issues add up to create unnecessary complexities which could end up costing time and money if not given the appropriate amount of attention. Therefore, when using the VIPER architecture one should always take care to fully understand all aspects before proceeding with development.

The way data is stored also plays a role in app architecture since it affects how data can be accessed by users or systems within the application. Databases are commonly used as they provide reliable storage mechanisms with features such as automatic backups and access control capabilities. However, there are different types of databases that should be chosen based on your specific requirements - relational databases such as SQL may be preferable if you need complex queries while NoSQL databases such as MongoDB may be better suited if you need flexibility in your data structure or require faster read access times.

Additionally, app architectures also factor into security considerations as well since they affect how easily malicious actors can gain access to sensitive information within an application or network of connected systems. Therefore security best practices must be taken into account when designing an app architecture including using secure authentication methods like two-factor authentication (2FA) whenever possible and ensuring that any communications between systems are encrypted so that data cannot be intercepted by third parties.

In summary, app architecture is a crucial part of developing successful applications since it determines how efficiently they run and whether they meet user expectations when it comes to performance, scalability and security considerations. Properly selecting a suitable software framework for your project along with carefully considering your data storage needs will help improve your chances at success when creating new apps or updating existing ones!



Common Mobile Application Architecture Mistakes to Avoid



When it comes to creating a mobile application, the architecture of the software is one of the most important aspects in order to ensure that everything runs smoothly and efficiently. A good application architecture should be able to address all the requirements of the current business context while also making sure that it can easily scale and evolve in response to changing needs. Unfortunately, there are some common mistakes developers make when designing an application architecture that can lead to major problems down the line. 

One of the biggest mistakes is overengineering or trying to build too many features into an application. Overengineering can often lead to unnecessary complexity and bloat, resulting in long development times, poor performance, and a lack of scalability. Additionally, if too much time is spent focusing on features instead of usability or bug fixes, users may end up frustrated with the product and abandon it altogether. 

Another mistake is failing to plan for user flexibility. Mobile applications must provide users with enough options to customize their experience for them to remain engaged over time. This means allowing for multiple themes, customizations, preferences, etc., as well as providing ways for users to store their data locally or sync with other devices. Failing to plan for these types of user-driven capabilities will leave your app lagging behind competitors who offer more flexible solutions. 

Finally, developers should also avoid making applications overly reliant on third-party services or APIs. While these services might seem attractive at first glance due to their convenience, they can create significant problems when something goes wrong or support is suddenly discontinued unexpectedly. Thus it’s important to design an architecture that provides a degree of self-reliance so that any disruptions won’t cripple the entire system right away. 

By avoiding these common mobile application architecture mistakes, you’ll be well on your way toward producing high-quality apps that satisfy customer needs while being able to quickly adapt and scale as needed over time.

How To Architect a Great Mobile App



When it comes to developing great apps for iOS, architecture plays an essential role in ensuring the app is successful. This means taking a strategic approach and creating a strong foundation that can support future growth and development. The most important aspects of great app architecture on iOS include writing modular code, sticking to common design patterns used on iOS, following the SOLID principles, and using automated testing. 

Modular code is beneficial because it helps developers keep code organized and focused on one purpose or feature at a time. This makes it easier to find bugs and make changes. Additionally, when all code is kept separate from each other, there’s less risk of conflicts between different components or features as the app grows in complexity. 

Sticking to common design patterns used on iOS instead of patterns from other platforms also helps ensure the success of an app. Design patterns are solutions to recurring problems encountered by developers during the creation process. By using design patterns that are already familiar to users of iOS devices, developers can create a better user experience without spending extra time learning new methods for coding their apps. 

For example: Do not call methods like you would call them in Java when developing for iOS, just because your team is familiar with Java development. Instead, stick to the conventions of iOS and Swift.

The SOLID principles provide further guidance when developing apps for iOS. It stands for Single Responsibility Principle (SRP), Open-Closed Principle (OCP), Liskov Substitution Principle (LSP), Interface Segregation Principle (ISP), and Dependency Inversion Principle (DIP). Following these five principles will help developers create more maintainable, reliable code with fewer bugs over time. 

Finally, automated testing should be used with any software development project in order to increase reliability and minimize bugs before releasing an application publicly. Automated tests provide feedback quickly about whether what was built works as expected or not; this helps developers catch problems early and fix them before users interact with them in released versions of their applications.



Benefits of Having a Well-Designed Mobile App Architecture for Maintenance, Long-Term Cost and App Reliability



Having a well-designed mobile app architecture can be extremely beneficial for maintenance, long-term costs and app reliability. By creating a well-thought-out architecture that is tailored to the goals of the company, developers can create an app that is easier to maintain, has fewer bugs and performs better in the long run. This will lead to fewer support tickets, reduced development time and improved customer satisfaction.

When it comes to maintenance, a well-designed mobile app architecture allows developers to quickly identify problem areas within the codebase and make changes as needed. As a result, there are fewer bugs present in the app and it runs more smoothly when users interact with it. Additionally, updates are easier to deploy with minimal disruption since only certain sections of the codebase need to be changed at any given time. This helps keep maintenance costs low over the life of the application.

In terms of long-term cost savings, a well-designed mobile app architecture allows developers to reuse components across applications or upgrades without having to write them from scratch each time. This reduces time spent on development tasks such as coding and debugging which can help reduce the overall cost of ownership for an application. Additionally, when components are reused in multiple apps or upgrades they become more reliable which decreases technical issues that may arise due to incompatibilities or other unforeseen glitches.

Finally, having a well-designed mobile app architecture ensures that problems can be identified quickly and rectified easily which helps improve reliability over time. This ultimately leads to better customer satisfaction since users don’t experience frequent bugs or crashes due to poorly written code. Additionally, since updates can be deployed more quickly with fewer disruptions this helps ensure that customers always have access to their favorite apps when they need them most instead of experiencing unexpected downtime due to poorly maintained software architectures.

Good Architecture, Automated Testing and Well-Written Documentation Prevent Sleepless Nights When a Developer Leaves Your Team



When a developer leaves your team, it can be a difficult time for everyone involved. It takes time and effort to find someone to replace them, and there is the risk that their code won't be maintained or updated properly. It's also possible that without them, your team could struggle with critical bugs and performance issues that they wouldn't have been able to fix without the help of the former developer. However, by implementing good architecture, automated testing and well-written documentation, you can prevent long nights of sleeplessness due to these potential issues.

Good architecture is essential for ensuring that your codebase remains maintainable after a key member leaves. By writing modularized code with clear APIs and interfaces between different parts of the system, it will make it easier for others on your team to understand what each part does and how it interacts with the others. This makes it simpler for new members to learn how things work more quickly, as well as makes debugging inefficient code much easier.

In addition to good architecture, automated testing should be used as much as possible throughout development cycles in order to ensure that new changes don't cause any unexpected behavior in existing functions or features. Automated tests also provide an extra layer of protection when it comes to refactoring or rewriting existing code; if all tests pass then you know you haven't broken anything (at least not intentionally). Automated tests are particularly useful after a developer leaves since they can help catch any bugs or regressions caused by their departure earlier rather than later on in the development cycle where fixing them would take more time and effort.

Finally, having well-written documentation can make a huge difference when someone new joins the team. A comprehensive set of documents outlining each component's purpose and how they interact with one another will save hours of guesswork and trial-and-error when trying to decipher someone else's codebase. Documentation also helps ensure that projects remain consistent even if developers come and go over time; anyone joining the team will immediately have all the information they need about how things work already at their fingertips.

By following these three simple steps - good architecture, automated testing and well-written documentation - you can put yourself in a position where you don't need to worry about spending sleepless nights when key members leave your team due to bugs or regressions caused by their absence. In short: plan ahead now so you won't have problems later!
