`xcodebuild -list -json` is exceptionally slow

[Max Howell]

In our CI builds the list operation takes ~21 seconds, and the build itself takes ~6 seconds (!)

This is insane, it will be worth investing time to figure out alternatives or optimizations.

Caught it:

{
  "project" : {
    "configurations" : [
      "Debug",
      "Release"
    ],
    "name" : "StreamReader",
    "schemes" : [
      "StreamReader-Package"
    ],
    "targets" : [
      "Path",
      "Path.swiftPackageDescription",
      "StreamReader",
      "StreamReaderPackageDescription"
    ]
  }
}
build session not created after 15 seconds - still waiting

fucking lol. What a crap tool xcodebuild is.

Oops. At least it’s not in the middle of the JSON blob?

[Chris Araman]

Was the slow runtime just due to virtualization (expected), or was there something else going on here?

[Max Howell]

Not fixed. There might be faster ways to get this info.
