Xcode Test Coverage

Xcode invocation tool - xed

xed is a command-line tool that launches the Xcode application and opens the given documents (xcodeproj, xcworkspace, etc.), or opens a new document, optionally with the contents of standard input.

If you work from the command line, this tool is a better option than open (which can open Xcode projects as well). Why?

• xed knows about the current selected Xcode version (open behaves unpredictably if you have multiple Xcode installed)
• You can use it open all files from a specific commit (with a little help explained below). It is useful on code-reviews or when you want to explore significant changes in the repository
• You can use it as a "quick open" helper. Helps with monorepo phenomena, when you have hundreds of projects in the repository (I will show you an example below)
