Detect screen load delay in iOS apps

What are Screen Loading Delays in iOS and iPadOS apps?

Screen loading delay is a common issue in iOS and iPadOS apps that can negatively impact user experience. Screen load delay refers to a non-ideal amount of time it takes for a screen to load after a user has requested it.

This can result in users experiencing unresponsiveness or sluggishness while navigating through the app. In some cases, screen loading delays can lead to users abandoning the app due to frustration or perceiving it as poorly designed or developed.

Reasons for Screen Loading Delays in iOS and iPadOS apps

• Large Image Files: Screen loading delays in iOS and iPadOS apps can be caused by the presence of large image files. These files can slow down the screen load time as they require more time to be loaded and rendered. To solve this issue, you can use compressed images or optimize the images before using them in your app.
• Complex Layouts: Another reason for screen loading delays is the use of complex layouts in the app. Complex layouts can increase the time it takes to render the screen, thus slowing down the overall load time. You can optimize your layouts by using more efficient layout structures like RelativeLayout or ConstraintLayout, which are designed to handle complex layouts more efficiently.
• Heavy Processing: If your app performs heavy processing tasks or computations during the screen loading process, it can slow down the screen load time. To address this issue, you can optimize the processing tasks to make them more efficient and use multi-threading techniques to speed up the process, ensuring a smoother and more responsive user experience.

How do we use the information in the screenshot to fix Screen Loading Delays in iOS and iPadOS apps?

The issue report will contain the name of the activity, along with data points such as the activity trail, which is a chronologically ordered list of events that occurred prior to the issue. This trail shows the point where the delay occurred.

Setting custom activity trail markers will provide more granularity to the activity trail, making it easier and faster to identify the root cause of the problem.
