Opening import file for module <framework>: Permission denied

Question

I set up a remote Git repository and Xcode Server on another computer, then created a bot in Xcode. Every time I try to do a new integration, it fails with an error like this:

Assertion: Opening import file for module 'Accelerate': Permission denied
     File: <filename>.swift:9

If I comment everything in this file, bot starts showing same error for another framework (and another .swift file). It can be either Swift or Objective-C framework.

Search Paths for this project is: $(PROJECT_DIR), and Always Search User Paths is set to Yes

I'm using Xcode 7.2 beta 2, but I was facing the same issue on Xcode 7.1 from the App Store. I tried restarting Xcode and both server and development Macs, it doesn't help. The project compiles and runs successfully on my development machine.

I had the same error when I tried to build and run the tests for my own framework on continuous integration server (Xcode Service Bots). The problem was first observed after upgrading my Server app to Version 5.1 (15S5127) and Xcode to Version 7.3 (7D175).

In my case the solution turned out to be quite surprising. It took me lots of time to realise that the problem only shows up when I use Nimble framework. When I remove import Nimble from my test and use standard XCTest assertions, the problem goes away.

What helped in my case was making sure that before integration, the Nimble framework is rebuilt. I am using Nimble with Carthage, so I only had to add the following command in the Before Integration Trigger:

cd NimbleCarthageProblem && /usr/local/bin/carthage bootstrap --platform iOS

See also screenshot:

After that it builds and tests run successfully.

From your logs I can't see if you are using Nimble - if you do not, than it means that the problem is somewhere else and I just experienced its another revelation.

I still do not understand why is the problem only happening on the build server during integration. Even if I log into build machine, check out the source code, and build it with Xcode right there - everything is fine. It only fails on the bot during integration. The solution is not ideal for another reason: Nimble has to be rebuilt before each integration and cannot just be included in the source code (if one finds this a better approach).

If I hope someone else will find the actual solution. I do not blame Nimble - it is most certainty a combination of things.

I created an example project where the problem and the solution are described in more details. It can be found here: https://github.com/mczenko/NimbleCarthageProblem.
