I install opencv how pods, and when i run app in my ios devise i have this issue.
opencv2.framework/opencv2(cap_ios_photo_camera.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7
In the build settings for your App Target, search for "Bitcode" and set Bitcode Enabled to NO.
Although I recommend you get the framework vendor to supply a Bitcode enabled version
You can disable the "Bitcode" as answered by @liamnichols.
But it is strongly recommended that you must use the frameworks with bitcode enabled. I suggest you to re-create the Opencv framework with bitcode enabled.
Please check this post, It'll help you creating opencv framework.
