Xcode 8 - IB Designables - Failed to render and update auto layout status, The agent crashed

Question

I recently upgraded to Xcode 8 and I am having issues with the Storyboard.

If I open the project and I don't have the Storyboard open, it will compile and run just fine. Once I open up the Storyboard, I get multiple errors about IB Designables as shown below.

These views are the only views that are using custom views from TextFieldEffects and BEMCheckbox that I imported using Cocoapods.

You can try one of the following to figure out the cause:

1. look for the IBDesignablesAgentCocoaTouch logs in this directory: ~/Library/Logs/DiagnosticReports and see the cause.

Note: for user with Catalina: look for IBDesignablesAgent-iOS_<DATE>-<MAC_NAME>.crash

2. Go to the Editor -> Debug Selected View while selecting your @IBDesignable UIView in your storyboard, and see the stack trace.

3. Delete Derive Data folder.

   Xcode Preference -> Location -> Derived Data
   /Users/YourMacName/Library/Developer/Xcode/DerivedData
   

4. Clean your project Shift + Command + Alt + K.

5. Build your project Command + B.
