Carthage update is failing with error 'could not posix spawn 35'

enter image description here

I have an application which was developed in Xcode 7.3 and Swift 2. Now I am trying to convert it to Swift 3.0.2, as the dependency manager I am using is Carthage. Now I am updating my Carthage so that all the frameworks should support swift 3.0.2. For this, first I have used the following command:

"carthage update --platform iOS"

It now fetches all the dependencies and check out all the dependencies but then after checkout it starts to build the dependencies and while building the dependency it just fails with an error.

Here is a attached screenshot of the error. I am totally blank on what I am missing in this case:

Solution

  • When I faced the problem , this is how I resolved it:

    1. I deleted everything that was checked out and got all new fetches and builds
    2. Ran carthage update --no-build && carthage bootstrap

    This problem mainly occurs in Xcode 7.3 beta2 (7D129n) toolchain. Carthage version0.12 will build the cartfile successfully if you set xcselect to 7.2.1.

    Version v0.11 didn't have this problem. The problem occurs during the build, maybe because all the versions of Carthage dependencies don't match too. I also read a few posts which asked me to supply with sudo carthage update --platform iOS --no-use-binaries.

    And you're using a really old version of Xcode. I'll suggest you to upgrade.
