Getting a fatal Error on "precibProbability = currentWeather..."

I get an error on that line:

    precibProbability = currentWeather ["precibProbability"] as Double

Error description: fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)

I already tried to debug, didn't work, please help

Daniel, hi.

I just caught the same error.

I re-cheked all variables names in struct Current and found few misspells. To get right names I printed out weatherDictionary and compared actual data with my var names. After I fixed misspells all works fine.

As I can see, you have just the same problem. It should be:

precipProbability = currentWeather["precipProbability"] as Double

Hope it will help.

Thanks! That one space wasn't the fault, but after I rechecked my code four times, I finally found my mistake.
