-17 is "Could not connect to lockdownd: Password protected "

Is your device unlocked? Does ios/Runner.xcworkspace run in Xcode?

[saschak094]

xCode does not run at all.
Yes my phone is locked, but I just connected it to charge it. I wanted to run my app on the Android simulator.

[jmagman]

Did you have the emulator selected as the targeted device? Or your plugged in, locked iOS device? https://flutter.dev/docs/get-started/test-drive?tab=vscode#vscode
