Xcode cannot build IPA file

Question

I am trying to build a file IPA by Xcode 6.1.1. But my Xcode say:

"The password supplied for the account @"xxx" was rejected.Please make sure that your password is correct in the Accounts preference pane"

What's happen to my Xcode? I have to update to 6.2, right?

Answer 1

It is because one of your account logged in have experiencing password changes. You can remove that error by doing this;

Go to XCode->Preference->Accounts

Delete the account that causes a problem, or change the password to the correct one.
