Detect iOS Function Failures & Impact

Function Failures in iOS and iPadOS apps

Function failures in iOS and iPadOS apps refer to instances where specific code-level functions do not execute properly or as intended, which can be caused by multiple reasons. The Appxiom Framework provides the ability to track and report individual functions by utilizing the Fn.call API or the Fn.start and Fn.end APIs.

When a function is tracked, any issue that prevents it from being executed will be reported, allowing developers to investigate and fix the underlying problems.

Why does this happen?

Function failures in iOS and iPadOS apps can occur for a variety of reasons. Some common causes include:

Delayed execution: This occurs when a function takes too long to complete, leading to performance issues.

Exceptions thrown during runtime: Unhandled errors, invalid type casts, or memory access problems that occur while the app is running.

Incorrect return values: When a function executes but returns a value that does not match the expected state, causing logic issues in the app's workflow.

Identifying the specific reason for a function's failure is critical for developers to effectively debug and resolve the issue.

How to fix it using Appxiom

• Locate issue report: The issue report will provide a detailed description of what went wrong during the tracked function execution, along with the return types and their values.
• Trace activity trail: The data points will include a list of individual parameters and their types passed to the function during runtime.
