iOS run --l failing due to signing, even though XCode run works

I’m getting the following error when trying to run a livereload version to fix some bugs:

Check dependencies
Code Signing Error: No profiles for 'xxx' were found:  Xcode couldn't find any iOS App Development provisioning profiles matching 'xxx'. Automatic signing is disabled and unable to generate a profile. To enable automatic signing, pass -allowProvisioningUpdates to xcodebuild.
Code Signing Error: Code signing is required for product type 'Application' in SDK 'iOS 11.2'

I know what this error means, and I have set up my provisioning profiles and can run the app normally when I build iOS and run from xCode. How can I setup the Ionic CLI to work as well? Livereload would really save me time
Thanks a lot!
