如何动态获取IOS模拟器设备的UID，然后安装到该设备中

Question

How to dynamically get the UID of the IOS simulator device and then install it in that device. I currently have this BASH script which does the job, however, when I run that code on a different machine, I need to manually change the ID every time which makes the automation difficult. How can I get the UID just by defining the device type such as IPHONE.8 get the ID and use that instead

#!/bin/bash
export PATH=/usr/local/bin:$PATH

# define variables
DESTINATION="platform=iOS Simulator,name=iPhone 8,OS=13.4.1"
IPHONE_VERSION_ONE="iPhone-7"
APPDIR="$HOME/Library/Developer/Xcode/DerivedData/"
APP_NAME="In-House-iphonesimulator/test.app"
PHONE_ID_ONE="AB877AA-2178-4C29-BF4F-556456C"


xcrun simctl install $PHONE_ID_ONE $APP_LOCATION || { echo 'Unable to install App to Iphone7' ; exit 1; }

Also i put the below answer in the variable, however how to put quotes when store it in a variable?

PHONE_ID="instruments -s devices | grep -m 1 "iPhone 8" | awk -F'[][]' '{print $2}'"

Answer 1

instruments -s devices | grep "iPhone 8" | awk -F'[][]' '{print $2}'

Here what this command is doing:

1. Listing all of your iOS devices
2. Searching for iPhone 8 over the results
3. Splitting the string by square brackets and printing the second token.

So you as a result should get UDID only: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

If you have more than one iPhone 8 simulator in your system, you can limit the output by adding -m 1 key to the grep command:

instruments -s devices | grep -m 1 "iPhone 8" | awk -F'[][]' '{print $2}'

Just assign the result of this command to your PHONE_ID_ONE variable using $() :

PHONE_ID="$(instruments -s devices | grep -m 1 'iPhone 8' | awk -F'[][]' '{print $2}')"

Hope this helps

Answer 2

With xctrace for example

   xctrace list  devices | grep -m 1 "iPhone 12" | awk '{print substr($0,length($0)-36,36)}'

Answer 3

I have used below command to get the device id of launched Simulator.

xcrun simctl list devices | grep "(Booted)" | grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})"

We can get the id of specified device by given device name if there are multiple devices are launched

xcrun simctl list devices | grep "(Booted)" | grep "iPhone 12" |grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})"

Answer 4

You can get the list of simulators together with their ID:

instruments -s devices
