Crashlytics error: Undefined symbols for architecture arm64
Crashlytics and Fabric require you to link your target against the following:
- Security.framework
- SystemConfiguration.framework
- libc++
- libz
Just select your target -> Build Phases -> Link Binary with Libraries -> add the ones missing.
I hope it helped.
I solved this issue by just adding $(inherited) to other linker flags in Build Settings.
I run into a similar issue, when I was updating an app that was created before Xcode 5.
Since Xcode 5 new projects build with modules enabled by default. In my old app "Enable Modules" was set to "No". So this was the solution.
