Common Mistakes iOS Developers Make When Going for the App Development Process

The second-largest mobile operating system in the world is Apple's iOS. Additionally, it has a very high adoption rate, with the most recent version being used by more than 85% of users. These dedicated consumers have high standards, so if your software has flaws, expect to hear about them. Unfortunately, it's also hard to bounce back once the one-star ratings start coming in.

Many engineers have shifted to mobile development as the need for iOS developers continues to soar (more than 1,000 new apps are submitted daily to Apple). Proper iOS knowledge, however, goes much beyond simple code.

Here are some key aspects you must know when going for iOS app development in New York.

Lack of comprehension of asynchronous processes

Mismanaging asynchronous code is a relatively typical form of error among inexperienced programmers. Let's think about a typical situation: The user opens a screen with a tabular view. Then, we refresh the UI after retrieving data from the server. Unfortunately, reload data will be called before obtaining the new data because fetching data is an asynchronous procedure and won't instantly return new data.

Running UI-related code outside of the main thread

Imagine that despite using the revised code example from the prior standard error, our table display still needs to be updated with the new data even after the asynchronous process has successfully finished. What could go wrong with such straightforward code? We can better comprehend by placing a breakpoint inside the block and discovering which queue this block is called. Since our call is not in the main queue, where all UI-related code ought to be run, there is a significant likelihood that the behaviour above is taking place.

Misunderstanding concurrency and multithreading

Concurrency may be compared to a super sharp knife: If you're not careful or experienced enough, you can easily cut yourself, but if you know how to use it properly and securely, it's beneficial and efficient.

No matter what sort of apps you create, there is an extreme likelihood that you will need concurrency even if you try to avoid utilising it. Your application may greatly benefit from concurrency.

Not understanding the dangers of mutable objects

Even though Swift makes it much easier to prevent value-type errors, many developers continue to work with Objective-C. Mutable objects can cause hidden issues and are extremely risky. Immutable objects should always be returned from functions, yet, most developers need to be aware of this convention.

Not understanding the principle of iOS

If you've ever used an NSDictionary and a custom class, you may be aware that if your class doesn't comply with NSCopying as a dictionary key, you cannot use it. Most programmers have never questioned Apple's decision to apply that limitation. So why does Apple make a replica of the key and use it instead of the original?

Understanding how NSDictionary functions inside is essential to understanding this. It is only a hash table, technically.

Final Wrap

The iOS platform is robust and developing quickly. Apple continuously works to add new hardware and features to iOS while also developing the Swift programming language. If you're planning to go for an app development process, connect with a professional company here in New York.
