Issue when changing environment from Sandbox to Production in SalesforceMobileSDK-iOS

[dheeraj-bartwal]

I am using the SalesforceMobileSDK-iOS, and everything works fine initial run. However, when I change the environment to Production by tapping the gear icon on the login screen, the app crash.
The app crashes with the following error:

Steps to reproduce:

1. Launch the app.

2. On Login Screen Tap the gear icon and change the environment to Production.

3. The app crashes with the following error:
   *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSDictionaryM setObject:forKeyedSubscript:]: key cannot be nil'

4. Version of Mobile SDK Used: 11.1.0

5. Issue found in Native App or Hybrid App: Native iOS App (Swift)

6. OS Version: 17.0

7. Device: Simulator iphone 15 Pro.

8. Actual behavior: The app crashes with an uncaught exception when trying to set a nil value in a dictionary, likely due to missing or incorrect configuration for the Production environment.

9. Expected Behavior: The app should successfully switch to Production without crashing.

10. Error Log: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSDictionaryM setObject:forKeyedSubscript:]: key cannot be nil'

Could you try our latest release, 12.2.0, to see if the crash is still there? And if it is, can you see what the crashing line of code is?
