Ionic emulate ios - target device errors


I can run ionic emulate ios and let the cli choose the emulator it works.

When i try to target a specific device I get the following errors:

ionic cordova emulate ios --target=“iPhone-5s, 10.2” -l -c -s

Error: Cannot read property 'name' of undefined

[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

Your plugins may be out of date.
TypeError: Cannot read property 'launchBrowser' of undefined


This might be caused by this:

Although you are not really on the newest Xcode version, so I am not sure. Also the additional output with launchbrowser you get seems different.
