Is your team provisioning profile showing up in Xcode?

yes it is showing...pls see attachment. everything is a tick and seems like theres no problem at all.
but whenever i close this xcode file and build in stencyl, then i come back to this xcode file.. the team automatically goes back to none.

Go to Xcode > Preferences > Accounts.  Your Apple ID should show up on the left side but you can add it if it's not there.  Then click on View Details and see if your team provisioning profile is listed.

The provisioning profile is showing up...i downloaded it and after closing xcode ... everytime i go back to Go to Xcode > Preferences > Accounts and the provisioning profile download button is still showing...

Mine just showed up and I didn't need to download.  I'm not sure what you need to do next.

ic ... not sure too...guess i will just try to do all the steps again...
