Application ID


Expected Behavior

Please describe the expected behavior of the issue, starting from the first action.

  1. I make a find request using a DataQueryBuilder and use either setRelated() or setRelationsDepth()
  2. An object or an array of objects is returned and the relations are also populated
  3. I can access the relations and map them to a Swift array of that object type.

Actual Behavior

Please provide a description of what actually happens, working from the same starting point.

Be descriptive: “it doesn’t work” does not describe what the behavior actually is – instead, say “the request returns a 400 error with message XXX”. Copy and paste your logs, and include any URLs.

  1. A request is made and data is returned
  2. The data has relations, but the relations do not convert properly to locally defined classes
  3. You can see in the screenshot below that the data is returned, but can’t be mapped to an array of the data’s type

Reproducible Test Case

Please provide a simple code that could be run in a new clean app and reproduce the issue.

If the issue is more complex or requires configuration, please provide a link to a project on Github that reproduces the issue.

Bitbucket Link:

  1. run pod install
  2. start the app
  3. place a breakpoint on line 40 of CompaniesViewController
  4. type in “Micro” in the search bar
  5. see that the returned data “companyData[0]” has data for the relation “sheets”
  6. in the xcode console type: po companiesData[0].sheets
  7. see that this prints out an empty array and isn’t properly mapping the data to the swift class STSheet
