how to get list of available ios simulators?

Question

i want to list available ios simulators as in below format ( iOS version should take from JSON key )

{
  "name": "iPhone 5s (11.4)",
  "udid": "FB6B3F7F-E6CD-4F64-8EC4-6C07C86A25C8"
}
{
  "name": "iPhone 6 Plus (11.4)",
  "udid": "768AE0B3-F77A-4DF4-8198-74CB2D598D19"
}
...
{
  "name": "iPad Air (11.4)",
  "udid": "396C0E3A-7DFD-41BD-9E05-28A27E6BB4AB"
}
{
  "name": "iPad Air 2 (11.4)",
  "udid": "1AD4AC1A-B45B-4869-9778-B5572D4CE031"
}
...
{
  "name": "iPhone 8 (13.2)",
  "udid": "71E02A7B-BCBB-45D8-8638-E5381B420406"
}
{
  "name": "iPhone 8 Plus (13.2)",
  "udid": "D3333C55-2D0A-4999-B6D2-450C637C9248"
}
...
{
  "name": "iPad (7th generation) (13.2)",
  "udid": "0543121E-86DC-4BC9-933F-60AA31D219CD"
}
{
  "name": "iPad Pro (11-inch) (13.2)",
  "udid": "1979F272-E938-45AA-9717-A5228AF6EBF1"
}
...

i tried with something like this

xcrun simctl list --json devices available | jq '.devices | with_entries(select(.key|contains("com.apple.CoreSimulator.SimRuntime.iOS")))'

but i was unable to implement rest of the jq manipulations to achieve expected format.

output for xcrun simctl list --json devices available as below

    "com.apple.CoreSimulator.SimRuntime.iOS-11-4" : [

how do i list available ios simulators as expected format ?

Answer 1

The version info that you're trying to grab is part of the devices keys. So you'll want to extract that out and build out your results formatted as needed. You could use contains combined with substrings to perform the extraction but using capture/1 here could simplify the process.

Here's one way you could do it:

$ xcrun ... | jq '.devices | to_entries[]
  | (.key | capture("com\\.apple\\.CoreSimulator\\.SimRuntime\\.iOS-(?<version>.+)")) as {$version}
  | .value[] | {name: "\(.name) (\($version|sub("-"; ".")))", udid}'
