Common Mistakes that every Ios developer should avoid

 
Building a successful iOS application is no easy task. It requires solid systems programming knowledge coupled with boundless creativity and some hard-selling. It also demands that you have better debugging skills than your competitors. This is because even the best of developers are bound to make mistakes as they churn out tons and tons of code. This is why it is important to identify common mistakes and look for them during the development stage itself. In this article, we present to you some common mistakes that you, as developers should avoid when building applications in iOS.

One of the most common mistakes that every iOS developer makes while he/she develops apps is memory errors, which many new iOS app developers often do commit when designing and developing applications. These mistakes are highlighted below for you to be aware, as upcoming iOS developers of such critical iOS memory mistakes.

Most developers forget to include the dealloc method in each class, which causes memory management problems during development. Ensure that you make appropriate dealloc calls in each class to avoid such issues.

It also happens that developers, many a time, do not call the super dealloc method from dealloc, that later on results in crash and serious issues in your app development. Remember that you cannot directly call a dealloc method. You should first call the super dealloc and that, only in your dealloc method.

NSLog Statements can be extremely helpful in debugging an app, but overuse it and you could slow down the performance of the app as a whole. The more you use NSLog statements, the more memory it will consume and in the end, you may end up getting a memory warning from the app itself. Try to avoid such mistakes and bypass NSLog statements if you don't really need them.

Underestimating iOS debugging commands: New developers are often unaware of the power of iOS debugging tools and never use them during development. MallocStackLogging, NSDebugEnabled and other environment variables can help you identify common causes for crash etc. So, try to familiarise yourself with iOS debugging commands and use them within your app development to avoid memory issues.

Apart from these major memory errors, many developers also forget to set pointers nil after releasing them, preferring to use retainCount of the objects which causes memory issues later.
