pip :

pip install py-ios-device

python version: 3.7 +

Instruments：

• Get system Memory and CPU data
• Get application Memory and CPU data
• Get FPS data FPS <= 60
• Get FPS and Jank data FPS <= 120
• Get network data
• Set the device network status. eg: 2G, 3G ,100% Loss
• Set the device behaves as though under a high thermal state
• Monitoring app start、exit、background
• Launch and Kill app
• Run xctest. eg: WebDriverAgent
• Dump core profile stack snapshot
• Analyze the core profile data stream
• Get Metal GPU Counters
• Get App Launch Lifecycle
• pull && push form the device

Other

• Profiles & Device Management. eg: Install and uninstall Fiddler certificate
• Get syslog
• Get crash log
• Get the captured packet traffic and forward it to wireshark
• App install and uninstall
• Get device battery
• Set simulate-location options

Usage：

Support iOS 17 (Command line is not supported )

pip install pymobiledevice3
sudo python3 -m pymobiledevice3 remote start-tunnel

# Recommended to use go-ios, which has better transmission performance
npm install -g go-ios  
sudo ios tunnel start || ios tunnel start --userspace
curl http://127.0.0.1:60105/tunnels

from ios_device.remote.remote_lockdown import RemoteLockdownClient
from ios_device.servers.Instrument import  InstrumentServer
from demo.instrument_demo.sysmontap import  sysmontap

# support ios tunnel start --userspace
# [{"address":"fd17:cafe:59d4::1","rsdPort":54934,"udid":"00008101-0018242C3XXXXXXXXX","userspaceTun":true,"userspaceTunPort":60106}]

host = 'fd17:cafe:59d4::1'
port = 54934  
with RemoteLockdownClient((host, port), userspace_port=60106) as rsd:
    rpc = InstrumentServer(rsd).init()
    sysmontap(rpc)
    rpc.stop()
