CLI 3.12.0: "Failed to install the requested application" on emulate

Ionic Framework ionic-v3
1

After updating to the cli v 3.12.0 if I try to run my app in the simulator with the following command
ionic cordova emulate ios --target="iPhone-8" -l -c
the app builds correctly, the simulator show up but (i guess) the process could no be attached to it, and therefore this error occurs:

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=2):
Failed to install the requested application
An application bundle was not found at the provided path.
Provide a valid path to the desired application bundle.

If I try to run the app from xcode (9.0 (9A235)) it builds and runs smoothly in the iPhone 8 Simulator.

I tried to change device target ( I tried the iPhone 7 / 7 plus / 8 / 8 plus / X ) with no success.
I run OSX Sierra on a late 2013 MBP.
furthermore I tried all the above in a fresh app with no success.

I am also seeing this issue

Have you tried running just ionic cordova emulate ios -l -c? Or without the -l -c even?

What is your ionic info output?

Sorry I forgot to post it, here it is

These all can be updated.

Same here.

cool, can you please provide the syntax to do so?

edit.
Nevermind. google did the trick.
for who is interested in how to update
sudo npm install -g cordova
npm install @ionic/app-scripts@latest
and you’re good to go.

But this unfortunately did not solve the problem :frowning:

Were you able to fix this problem? I am having the same problem.

The issue “solved” itself by updating the cli, it came back another couple of times by updating the cli.
I never found the actual cause though. So if anybody finds it, I’d be more than glad to hear about it.
