Hello,

I was trying to download tiles in the link provided with sample snippet having Washington DC Downtown area lat long but I always receive the Failed to download error. Could you please address this issue ?

Could you provide code of your specific example? I tried to reproduce your issue, just added the code from your link to the project and the download worked fine. Saw progress, completed event was called.

Failing to load certain tiles is fine, by the way :)

If you don't see the map being rendered, you could try calling source?.notifyTilesChanged(false) on your NTPersistentCacheTileDataSource

Additionally, this is not an issue directly related to our mobile-ios-samples repository. In the future, I suggest you use stackoverflow for questions and mobile-sdk repository for issues with our SDK.
