If you search around there are a lot of solutions presented to solve this problem. But a few them are outdated or very specific to a certain domain. Recently I ran into the same issue with Charts and Xcode refusing to build to my device with the same error message. The problem you're having has nothing to do with your free developer account but rather with the keychain.
To solve it you'll have to do the following:
Open Terminal and type: security set-key-partition-list -S apple-tool:,apple:,codesign: -s /Users/YOUR_USERNAME/Library/Keychains/login.keychain-db
You'll be prompted for your password. If you enter your password correctly and are repeatedly told it is incorrect go into Utilities -> Keychain Access.
- Select and deselect the lock. Enter your password when prompted. Re-enter the command on terminal input your password and then clean/build on Xcode. Everything should work as before.
