xcrun

Simctl

get a list of all simulators. Actually running simulators will be marked as (booted in the list). Identify the UUID for the simulator that you want to use from the list

xcrun simctl list

filter names of booted simulators in seperated lines

#!/bin/bash

cd;
IFS=$'\n'; # for likes to split strings into items by IFS, to process the string line by line it is necessary to reduce IFS to \n
for i in $(xcrun simctl list -v devices | grep Booted); do
CURRENT_DEVICE="${i:$((${#i} - 47)):36}"; # extract 36 long substring beginning in -46 position which should be UUID
xcrun simctl shutdown "$CURRENT_DEVICE";
xcrun simctl erase "$CURRENT_DEVICE";
xcrun simctl boot "$CURRENT_DEVICE";
done;
unset IFS;

kill all devices

xcrun simctl shutdown all

wipe all devices

xcrun simctl erase all

Restart a specific device

xcrun simctl boot "iPhone 8 Plus"

Force install an app to a simulator

$xcrun simctl install ~/Library/Developer/Xcode/DerivedData//Build/Products/Debug-iphonesimulator/.app

if you intentionally chaged the deriveddata path you should naturally use that path here.

(should look similar to this: xcrun simctl install F77DFD12-730C-48A8-B937-85D3AE1C1EA8 ~/Library/Developer/Xcode/DerivedData/Mein_o2-alhzujwksbfabyeyappxkmiqezvt/Build/Products/Debug-iphonesimulator/Mein o2 Beta.app)

xcodebuild

You can't just dump a normal .ipa or .app file into the simultor. You need a specific .app file for a simulator. XCode actually creates this file automatically each the time you build an .ipa but will not hand it to you. You have to go into system folders and get it for yourself.

Because XCode makes the file for every .ipa build you can probably immediately find it in ~/Library/Developer/Xcode/DerivedData//Build/Products/Debug-iphonesimulator/.app

For Jenkins jobs you will want to build with CLI commands. Navigate to the project folder and do the following.

$xcodebuild -workspace './Mein o2.xcworkspace/' -scheme '' -arch x86_64 -sdk (example: >$xcodebuild -workspace './Mein o2.xcworkspace/' -scheme 'Mein o2 Beta' -arch i386 -sdk iphonesimulator12.1)

Either way you can search for the the results using >$find ~/Library/Developer/Xcode/DerivedData -name ".app"

You can change the weird path with the compiler option -derivedDataPath //

example cli invocation to build for simulator

xcodebuild -derivedDataPath <some path> -workspace '<filename>.xcworkspace' -scheme '<one single scheme>' \ -sdk iphonesimulator12.1 -arch x86_64 clean build;

list available sdks

xcodebuild -showsdks

xcode-select

For switching between XCODE root paths of multiple coexiting XCODE bundles

This will dump a list of discovered paths: xcode-select -p /Applications/Xcode-7.2.app/Contents/Developer This will programmatically set the path to use: sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

Instruments

list available simulators

instruments -s devices

#Simulator

To start the simulator form command line do:

open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app/
