Investigate Feasibility of Speeding Up iOS Coverage Report Processing

[katia-sentry]

We've received a request from a customer to accelerate the processing of iOS coverage reports. An external solution, xcresultparser, has been suggested, but the customer doesn't trust this tool and we don't either to incorporate into our uploaders.

Goal:

To determine the feasibility and practicality of speeding up iOS coverage report processing with a in-house development solution

Tasks:

• Investigate approaches to speeding up iOS coverage report processing in-house
• Determine the feasibility and practicality of an in-house solution for this
• Suggest scope and timeline of in-house development
