🎯 Goal

Fix crash when opening message overlay in iPad with a TabBar

🛠 Implementation

Current Solution:

• Uses UIGraphicsImageRenderer, which does not crash when providing a CGSize.zero
• Changes topVC() so that it accounts for a tab bar controller

Shortcomings:

• The only problem at the moment is that the navigation bar is not part of the screenshot. I'm not 100% sure why the navigation bar is not being captured by the snapshot yet, but for now, this works as a workaround.

Ideal solution:

• We need to refactor the whole Overlay view to use a background blur overlay instead of a snapshot. The snapshot is too dependent on the app hierarchy, which ofc is error-prone and not scalable.

I created a ticket so that we can tackle this in the future: https://stream-io.atlassian.net/browse/PBE-6270

🧪 Testing

1. Open the app with iPad
2. Open a channel
3. Long press a message
4. It should not crash and it should show the message actions overlay view.
