Flutter can't connect to iOS simulator

I created first flutter app on Mac.

but I can't build it on iOS simulator. when I build it; an iOS simulator will run. and wait.

vs Code say to me;

-Cannot launch without an active device

-Failed to launch iOS Simulator: Error: Emulator didn't connect within 60 seconds

IDE : vs Code

my Macbook : MacBook Pro 2011 early

macOs version : high Sierra

flutter version : 13.8

xcode version : 9.4

Solution 1:

Open Xcode and go to preferences - > locations - > Command Line Tools and select Xcode 10 or above

Solution 2:

I have the same problem. Flutter doesn't see any simulators. Flutter required now Xcode 10.2 minimum. You can't run 10.2 on high sierra, therefore use flatter.

Solution 3:

Which device do you use as a Simulator? From the docs:

Make sure your simulator is using a 64-bit device (iPhone 5s or later) by checking the settings in the simulator’s Hardware > Device menu.

Run flutter doctor. Are there any errors?
