How to Increase iOS App Performance – 5 Quick Tips

Do you want to Increase your iOS App Performance In this world full of technology, iOS applications are rapidly growing with an increased number of users. The reasons behind its growth are the excellent set of features and functionalities these applications offer. At times you must have realized the need for a fabulous iOS application that could take your business towards success. Companies are switching over to this popular platform of iOS applications to take a step towards the transformation of their business processes. High memory and the ability to use even the features available in devices make iOS applications highly preferred among millions. However, as an iOS developer, you must have noticed a difference in your iOS app’s performance.

There are a variety of reasons behind the low performance of iOS applications. Have a look at the five best tips to increase your iOS app performance instantly.


After fetching a particular resource, it must have restriction for the iOS app not to fetch the same resource each time. It takes a lot of time to download the same information again and again. It also increases the load of iOS applications; that’s why you need to incorporate caching within your app—caching stores a copy for the resource after the first time it is fetched by the iOS application. This copy is saved on the disk so that the same resource can be used multiple times later without requiring fetching it every single time. It also benefits when the phone is not connected to the web, but till resource is available for you. By using caching inside your iOS application, the performance of your app will eventually improve.

Avoid Blocking Main Thread

Another way to make your iOS application perform better is to avoid blocking the main thread. It is one of the most important lessons, to follow as an iOS developer for building a high-quality app. It is must because if you block the main thread, your iOS app will become unresponsive. Blocking with long-running operation affects the performance, and the app doesn’t respond the way it should until the operation isn’t completed. Adopt the habit of using a background thread for your tasks that take a long time. The operation will also get blocked if the connection of the device to the web is slow, and you need some bytes. You can now write the code for multithreading with ease by using tools like Grand Central Dispatch.

Lazy Loading

Lazy loading is one of the software development concepts, which is popular among iOS app developers. According to this concept, you can postpone the object’s instantiation, which benefits the overall performance of the app. You can hold it until you need the object, depending on the object type. The cost for instantiation varies for a different object, which directly improves the app’s memory usage. For lazy loading objects, you can override for the getter, which is the most straightforward implementation to increase the performance. This concept can be applicable to different areas of iOS app development, whether you need to show your UI by default, use this concept. Collection and table views are the two elements that combine caching with lazy to optimize the iOS app’s overall performance.

Measure Performance

You may notice your iOS app getting slower at times, and it is due to specific reasons. To find out what is causing it to sower down, profile the app with a tool like instruments. It’s possible that you don’t get an apparent reason behind your app’s slow performance; you can use MGBenchmark. This library allows you to measure the speed of your iOS app’s code execution. It also tracks the bottlenecks within your code for the iOS app. This library contains Instruments tools, so you don’t need to use that along with an extensive range of features. All the features are remarkably robust, helping you to increase your app’s performance.

Stress Testing

Another way to optimize the performance of your iOS application is to perform stress testing. As your app works on a massive amount of data, it’s crucial to know whether your app can handle that pressure. Before releasing the app, you need to ensure the stress your iOS app can handle so that it doesn’t crash afterward. Your app may become unresponsive when loading with a variety of data. Verify the working of your application at all circumstances and mimic everyday situations to know how well your app performs. Create data sets to test the iOS application development company and populate it with a huge data load. Stress testing is the best way to know the breaking point of your iOS application so that you can improve for better performance.


iOS apps has high security and offer significant benefits to individuals and even organizations from small to large scale. These applications are highly preferred by most of the audience and even organizations. But the weak performance of the app may leave a negative impact allowing users to exit the app. Follow the above instructions described to increase the performance of your iOS app within seconds.
