Translation API Doesn't work in swift.

Question

Hi.

To use translator API, I tested sample code offered from MS. (https://github.com/MicrosoftTranslator/Text-Translation-API-App-V3-IOS)
But after build the project, I got just unwrapping error below.

"Fatal error: TranslatorV3Sample[3753:856508] Fatal error: Unexpectedly found nil while unwrapping an Optional value: file TranslatorV3Sample/Dictionary.swift"

I thought there is a problem on parsing data. So I tried to take a look at a data generated in parseJson function, to add simple code "print(String(data: responseData!, encoding: .utf8)!)".

But I also got error below.

"{"error":{"code":401000,"message":"The request is not authorized because credentials are missing or invalid."}}"

I think my account has some problems(api key or something), but I can't find where it is.
Anyone knows how to fix it??

I just want to build example code correctly or test my account any way.

My subscription is free trier, and iOS version is 14.4 and I tried in Dictionary.

Thanks

I got solution!

I can get data from api after add region information that is win azure portal, overview.

Example code in sendRequest function is below

{ ...

let azureKey = "*****ENTER-KEY-HERE*****"
let azureRegion = "*****ENTER-LOCATION-HERE*****" // no space

...

request.addValue(azureKey, forHTTPHeaderField: "Ocp-Apim-Subscription-Key")
request.addValue(azureRegion, forHTTPHeaderField: "Ocp-Apim-Subscription-Region")

... }

It is correct for me.

@태민 윤 I am curious to check if you have replaced your key in the files. I think in this case it should be updated here. According to the sample:

The app is written in Swift 4. Clone the app, get an Azure Text Translation Subsrcription, get your key, replace the text "ENTER-KEY-HERE" with your key and you are ready to run.

This needs to be done in all the code files.
