Download schema relative to root url

[Anteo95]

Bug report

Currently, even though rootURL can be provided as parameter to function

  public static func fetch(
    configuration: ApolloSchemaDownloadConfiguration,
    withRootURL rootURL: URL? = nil
  )

it is actually not used internally on all places in the ApolloCodeGen lib where it should be. This causes schema to be downloaded into incorrect folder.

Versions

• apollo-ios SDK version: 1.0.2
• Xcode version: 14.1 RC1
• Swift version: 5.7.1

Steps to reproduce

1. Try to generate code with ApolloCodeGen
2. Generated schema ends up in incorrect folder without respecting passed rootURL property

Thanks for raising the issue @Anteo95 and for the PR contribution. I'll take a look at the test failures otherwise we should be good to get this included in the next 1.0.3 release.
