Memory leak is a critical bug in watchOS apps, that often go unnoticed during development. Memory leaks can lead to EXC_BAD_ACCESS error and will manifest as app crashes in watchOS.

Memory leaks are caused when unused objects are not cleared from memory. It slows down the app, which affects the experience of the user. So detecting and fixing memory leaks as fast as possible is important for maintaining good user experience and thus retaining users. Tools like XCode Leaks Instrument available for watchOS will help developers detect memory leaks during the development of apps.

There are situations where developers tend to miss figuring out leaks during development. Such leaks are very likely to manifest in production.

This is where Appxiom come in. Appxiom watchOS framework monitors InterfaceControllers for retained objects and reports it in real-time.Appxiom detects memory leaks in watchOS apps just by extending InterfaceControllers from ObservableInterfaceController, a custom InterfaceController class provided by Appxiom.

Objective-c Integration​

@interface ProfileController : ObservableInterfaceController

@end

Swift Integration​

class ProfileController: ObservableInterfaceController {

}

Find the detailed documentation for Objective-C & Swift, on how to track memory leaks.

Appxiom reports memory leaks with relevant data points like leaked InterfaceController name, activity trail, device info, and device state info. This will help the developers to reproduce the memory leaks and find the root cause.

Here is a screenshot of the memory leak detected by Appxiom in a live watchOS app.

Memory Leak in watchOS appsMemory leak bug report provides the name of the InterfaceController where the leak occurred along with the total memory consumed by the app.

Apart from memory leaks, Appxiom also detects API call issues, frame rate issues, abnormal memory usage, crashes, exceptions, function failures & delays along with custom issues.

Memory leak is one of the most dreadful issues developers fear. It's even bigger challenge for mobile app developers as very often the device where the issue manifests is out of their reach. Most of the time developers will not even get crash reports caused by memory leaks. They usually manifest in the form of EXC_BAD_ACCESS.

Tools like XCode Leaks Instrument for iOS help developers identify such leaks during development time itself. But what is the guarantee that all such leaks are identified and all possible use-cases are tested properly? There is no guarantee, and that is the hard truth.

So what if the developer and the tester missed some use cases and there are memory leaks happening in production? Here is where Appxiom help the developer to get notified about the issue in real-time and that too with as much relevant data as possible so that (s)he can reproduce the bug. Appxiom auto detects memory leaks.

Appxiom report bugs to the dashboard with important data such as activity trail, device info, and device state info. This will help the developer to be aware of the leaks happening in their app that is running in their users' devices and also helps them to reproduce the memory leak.

Here is a screenshot of such a leak detected by Appxiom in a live app.

With such reports, developers are notified of the occurrence of a memory leak in a ViewController. Developers can then use the Leaks instrument to drill down the corresponding ViewController for the leak.

Apart from memory leaks, Appxiom detects API call issues, frame rate issues, abnormal memory usage, crashes, exceptions, function failures & delays. It also has the capability to report custom issues. The memory leak detection is available in our iOS Framework starting from version 3.1.0.
