title: Missing NSCalendarsUsageDescription key with purpose string after using Telerik library
body: <p>I used Telerik list view in my forms project. Yesterday, I uploaded it to App Store connect via Test Flight. It got uploaded from Application Loader but got rejected from apple with this email:</p>
  
  <p>App Store Connect</p>
  
  <blockquote>
    <p>Dear Developer, We identified one or more issues with a recent
    delivery for your app, "Local183". Please correct the following
    issues, then upload again. "Missing Purpose String in Info.plist File.
    Your app's code references one or more APIs that access sensitive user
    data. The app's Info.plist file should contain a
    NSCalendarsUsageDescription key with a user-facing purpose string
    explaining clearly and completely why your app needs the data.
    Starting spring 2019, all apps submitted to the App Store that access
    user data will be required to include a purpose string.If you're using
    external libraries or SDKs, they may reference APIs that require a
    purpose string. While your app might not use these APIs, a purpose
    string is still required. You can contact the developer of the library
    or SDK and request they release a version of their code that doesn't
    contain the APIs. Learn more

  <p>I have not used any calendar accessing code anywhere in my code but still they raised such issue I don't know why? But this never happened before implementing Telerik as I've already uploaded 2-3 versions of my app to app store connect and it never failed.</p>
