Fatal error: Unexpectedly found nil while unwrapping an Optional value

[estebanutz]

Hi, I'm trying to integrate your TurboController into my turbo ios app and I'm getting the error: Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value on line 224:

let environment = ProcessInfo.processInfo.environment["ENVIRONMENT"]! as String

When I ran your demo on my local machine no problems, so is this a configuration issue on my end or code compatibility with newer version of iOS? I noticed under Deployment target your demo is set to 14.5, while mine is 15.2, but even if I change mine to 14.5 I keep getting the error. Any help would be greatly appreciated!

Thanks!

I believe that this environment flag is only set when the app is run via Xcode. So when you run it on a device by tapping the icon it won't be set. You could change that line to something like this to default to production when running outside of Xcode.

let environment = ProcessInfo.processInfo.environment["ENVIRONMENT"] as? String ?? "PRODUCTION"

Replacing "PRODUCTION" with whatever environment you'd like to use.

@joemasilotti Thank you! That fixed the issue, but what's interesting is I ran your demo via Xcode and it does not produce the same error, that's throwing me off a little bit.

Running via Xcode is what sets the environment variable. So if you ran the demo against a device (or opened the demo via tapping the app icon) it will crash.
