If you use 'launch on' for a template project, when using a Mac, The build will fail for an iOS device.
Tested this issue on a Windows machine and the error does not occur.
I have attached the build log when I tested this issue.
1) Open a new template project on a Mac
2) Be sure to have an iOS device connected to the mac for launching on
3) Once the project is open, Use the 'Launch On' feature in the Toolbar to launch to an iOS device
4) Be sure to have the output log open
