I am using my Apple id(personal team) for my project. I am able to install on my ios device but when when my friend is trying to use my project with his apple id(personal team). He is getting this error "An App ID with Identifier is not available. Please enter a different string".
Soon we will purchase apple developer member program. but for now How should i configure bundle identifier so that we both use our own apple id.
It appears there is a logical answer to this issue. Apple has apparently gotten a bit more strict. So...
If your app's Bundle ID format is : com.my.app
It should now be : com.my.app.XXX (e.g.: com.my.app.ios)
Creating new App ID and provisioning profile will then fix the issue.
See the example in Apple's App Distribution Guide on Registering App IDs (Step 5). Note that the article as last edited on March 21, 2016, further implying this was a recent change causing this issue.

Downgrade from Xcode 7.3 to 7.2.1
To do so:
I hope this helps anyone else trying to find a logical answer to an illogical problem...
