Tested with 1.5.1 RC.

If I execute the following commands when the app is not installed on the simulaotr:

• tns livesync ios --emulator - installs an older version of the app, which is not correct
• tns run ios --emulator - installs the latest version of the app

Update:

the exact workflow for the issue described in the previous comment is:

1. tns create testApp
2. cd testApp
3. tns platform add ios
4. tns build ios
5. make a change
6. tns livesync ios --emulator

As a result, the app built at step 4 get deployed on the simulator which is correct because the livesync command does not rebuild the app,.
