Simulators not available

[MathildeDion]

Hey,
I am trying to start using Flipper but can't connect my iOS simulators.
I installed idb in a virtual environment.

Idb gives me this list:

But apparently none of the is available on Flipper ?

You must specify at least one 'Mode of operation'

Usage: 
   Modes of operation, only one of these may be specified:
    --udid UDID|mac|only       Launches a companion server for the specified UDID, 'mac' for a mac companion, or 'only' to run a companion for the only simulator/device available.
    --boot UDID                Boots the simulator with the specified UDID.
    --reboot UDID              Reboots the target with the specified UDID.
    --shutdown UDID            Shuts down the target with the specified UDID.
    --erase UDID               Erases the target with the specified UDID.
    --clean UDID               Performs a soft reset to the specified UDID.
    --delete UDID|all          Deletes the simulator with the specified UDID, or 'all' to delete all simulators in the set.
    --create VALUE             Creates a simulator using the VALUE argument like "iPhone X,iOS 12.4"
    --clone UDID               Clones a simulator by a given UDID
    --clone-destination-set    A path to the destination device set in a clone operation, --device-set-path specifies the source simulator.
    --recover ecid:ECID        Causes the targeted device ECID to enter recovery mode
    --unrecover ecid:ECID      Causes the targeted device ECID to exit recovery mode
    --activate ecid:ECID       Causes the device to activate
    --notify PATH|stdout       Launches a companion notifier which will stream availability updates to the specified path, or stdout.
    --forward UDID:PORT        Forwards the remote socket for the specified UDID to the specified remote PORT. Input and output is relayed via stdin/stdout
    --list 1                   Lists all available devices and simulators in the current context. If Xcode is not correctly installed, only devices will be listed.
    --version                  Writes companion version information to stdout.
    --help                     Show this help message and exit.

  Options:
    --grpc-port PORT           Port to start the grpc companion server on (default: 10882).
    --tls-cert-path PATH       If specified exposed GRPC server will be listening on a TLS enabled socket.
    --grpc-domain-sock PATH    Unix Domain Socket path to start the companion server on, will superceed TCP binding via --grpc-port.
    --debug-port PORT          Port to connect debugger on (default: 10881).
    --log-file-path PATH       Path to write a log file to e.g ./output.log (default: logs to stdErr).
    --log-level info|debug     The log level to use, 'debug' for a higher level of debugging 'info' for a lower level of logging (default 'debug').
    --device-set-path PATH     Path to a custom Simulator device set.
    --only FILTER_OPTION       If provided, will limit interaction to a subset of all available targets
    --headless VALUE           If VALUE is a true value, the Simulator boot's lifecycle will be tied to the lifecycle of this invocation.
    --verify-booted VALUE      If VALUE is a true value, will verify that the Simulator is in a known-booted state before --boot completes. Default is true.
    --terminate-offline VALUE  Terminate if the target goes offline, otherwise the companion will stay alive.

 Filter Options:
    simulator                  Limit interactions to Simulators only.
    device                     Limit interactions to Devices only.
    ecid:ECID                  Limit interactions to a specific Device ECID

Same here. Happy to help in any way

Hello. Can you please expand on what is meant by "virtual environment"?

Flipper requires idb and idb-companion available in $PATH to work with ios devices.

[thomasamaddeo-genie]

Same for me.
Running idb list-targets works and lists emulators.
Python was installed via mac installer and it added /Library/Frameworks/Python.framework/Versions/3.12/bin to $PATH in my .zprofile file.
idb and idb-companion were installed as per instructions here

With that said though, Flipper seems to be working fine (connecting to the app, showing logs etc) so just a "bug" with setup doctor itself maybe?

[summerkiflain]

I think by I installed idb in a virtual environment. she meant it she used .venv of python to install idb. I also installed idb using below commands:

`brew tap facebook/fb`
`brew install idb-companion`
`mkdir ~/.venv`
`python3 -m venv ~/.venv`
`source ~/.venv/bin/activate`
`python3 -m pip install fb-idb`

and now Flipper is showing green tick in front of IDB Installed like above picture but Simulators are available is red cross for me too, same like above picture.

I am on Macbook M3 Pro, Python came with homebrew when I installed, I think.

I had the same issue. I read through the error in setup wizard and noticed the following:

...
"/opt/homebrew/Cellar/[email protected]/3.12.4/Frameworks/Python.framework/Versions/3.12/lib/python3.12/subprocess.py", line 1955, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/bin/idb_companion'

Notice: No such file or directory: '/usr/local/bin/idb_companion'

I installed it via homebrew so my idb_companion, so I ran which idb_companion and found out the right path was: /opt/homebrew/bin/idb_companion.

I created the symlink between two paths. I ran:

sudo ln -s /opt/homebrew/bin/idb_companion /usr/local/bin/idb_companion

And now the ios simulators show up in Flipper. Hope this helps others!

[antonk52]

Thanks for sharing. Flipper checks idb_companion by running which idb_companion. Is /opt/homebrew/bin present in your $PATH?

flipper/desktop/flipper-server/src/doctor/index.tsx

Lines 209 to 211 in 1246c8b

	const hasIdbCompanion = await tryExecuteCommand(
	'which idb_companion',
	);

I have the same issue and I have my homebrew custom path on my $PATH env

This is work!!!
