Xcode 8.3 nvalid bitcode signature
My project is using P2PCamera SDK but not using Cocoapod then you need to rely more on lib
error: Invalid bitcode signature
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I can build and run success in Xcode8.2, but this is an error when I use Xcode8.3
I have this problem when I was trying to test an iOS device. Debug configuration with Build Active Architecture Only set to NO. After I have set YES, I can check my iPhone. 
This will fix the problem.
The problem might be related to a third party SDK integrated into your project using Cocoapods. do the following:
- Clear
derived data
and restartXcode
. - Clean and build.
Or, if you don't mind disabling the bitcode: go to the bitrate search settings and change " Enable Bitcode
" to " No
".
The problem might be related to the third party library lAVCtrl_armv7 , you can confirm this by editing the valid architecture to arm64 and recompiling.
For me it helped to "update the project to recommended settings" and clean up: fooobar.com/questions/240907 / ...
