问题
I have recently updated to Xcode 7 and now receive the following warning when I compile:
ld: warning: -read_only_relocs cannot be used with x86_64
I don't think I changed anything in the build settings or code to create this. Does anyone know what is causing this warning and how to remove it?

I have found the problem for those interested. As mentioned in the comment, I'm using the Twilio API and if you install this via cocoapods it adds the -read_only_relocs flag to the Other Linker Flags in Xcode (found under Build Settings). Not only does this generate the warning above (on the simulator) but it wont compile on an actual device because you can't have both BITCODE = YES and this flag. If you want to compile, you will need to set Enable Bitcode to No in the Build Options.
