So I tried to run my app on iPhone 7, and ASIHttp didn't work. After some search I saw that people are migrating to AFNetworking, so I decided to do the same. Here's what I did:

  • Updated Xcode to version 5.1
  • Followed the instructions here (setup cocoapods, installed afnetworking, changed project)

and tried to run. The first build failed with this message:

clang: error: unknown argument: '-fno-obj-arc' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

The only 2 reports I found about this are here and here

and they tell me to add some flag while doing the pod download:

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

Did that and tried again, to no avail. Now I can't even go back to the other project. Has anyone dealt with this problem so far? The option is in the command line, but I can't find anywhere to remove it. I don't think I should anyway.

Here's the command line, you can see the argument right after AFNetworking:

    It looks like you made a typo. It should be `-fno-objc-arc`. – Mick MacCallum May 16 '14 at 19:55
  • Thought so too, but all this was automated. I can't find where to change and test it, AFNetworking won't show in the Build phases. I also have TBXML linked in this project, and the flag is obj instead of objc, and it works fine. – cappeca May 16 '14 at 20:01

Check the Build Phases section for the Compile Sources, you should have the No Arc flag (-fno-objc-arc) there, just make sure the spelling is correct.

  1. Build Phases:

  2. Compile Sources

  • Yep. My mistake was to add AFNetworking and updating Xcode at the same time. This issue had nothing to do with AFN, but with the change of rules with Xcode 5.1. – cappeca May 19 '14 at 02:12
