# Visualize your iOS app changes in your GitHub pull request

Quite often I receive pull requests to review which change the user interface without describing or showing the changes from a user's perspective.

Today I'd like to teach you a workflow on how to improve such pull requests with existing tools.

1. 
Use the built-in functions in Xcode Simulator to either save (⌘S) or record (⌘R) your screen.

1. 
Use GitHub Saved Replies to create and use a markdown table with a "Before" and "After" column in which to drag & drop the files

Here is the code snippet I use for the saved reply

```
|Before|After|
|---|---|
|   |   |
```

Here is a video illustrating the workflow.
