我想以以下格式列出可用的ios模拟器（iOS版本应使用JSON键）
{
"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"
}
{

"udid": "D3333C55-2D0A-4999-B6D2-450C637C9248"
}
...
{
"name": "iPad (7th generation) (13.2)",
"udid": "0543121E-86DC-4BC9-933F-60AA31D219CD"
}
{

我尝试了类似
xcrun simctl list --json devices available | jq '.devices | with_entries(select(.key|contains("com.apple.CoreSimulator.SimRuntime.iOS")))'
但是我无法实现其余的 jq 操作以实现预期的格式。
xcrun simctl list --json devices available的输出，如下所示

如何将可用的ios模拟器以预期格式列出？
答案 0 :(得分：2)
您尝试获取的版本信息是设备密钥的一部分。因此，您需要将其提取出来，并根据需要格式化结果。您可以结合使用contains和子字符串来执行提取，但在此处使用capture/1可以简化此过程。
这是您可以做到的一种方法：
$ xcrun ... | jq '.devices | to_entries[]
| (.key | capture("com\\.apple\\.CoreSimulator\\.SimRuntime\\.iOS-(?<version>.+)")) as {$version}
| .value[] | {name: "\(.name) (\($version|sub("-"; ".")))", udid}'
