How does Apptimize \ Optimizely work on iOS?

Question

I\'m trying to figure out a few things about the implementation going on \"behind the scene\" for manipulating UI elements on the fly, straight from the web console on Apptimize

My name is Baraa and I'm a Software Engineering Intern working on the mobile team at Optimizely, so I can share some high-level insight into how the Optimizely SDK works on both Android and iOS.

On iOS, the Optimizely SDK uses a technique called swizzling. This allows us to apply visual changes to the application based on whatever experiments are currently active in our data file.

On Android, Optimizely uses reflection to attach the SDK as a listener for interaction and lifecycle events to apply visual changes to the application based on whatever experiments are active in the data file.

For the full list of methods that we swizzle on iOS and listeners that we intercept on Android, please check out this help article: https://help.optimizely.com/hc/en-us/articles/205014107-How-Optimizely-s-SDKs-Work-SDK-Order-of-execution-experiment-activation-and-goals#execute
