Follow the subsequent instructions to develop, debug, unit test, and integration test FirebaseCrashlytics:

• At least CocoaPods 1.6.0
• Install cocoapods-generate
• For nanopb and GDT:
  • brew install protobuf nanopb-generator
  • easy_install protobuf python

• Run Crashlytics/generate_project.sh
• open gen/FirebaseCrashlytics/FirebaseCrashlytics.xcworkspace

You're now in an Xcode workspace generate for building, debugging and testing the FirebaseCrashlytics CocoaPod.

Open the generated workspace, choose the FirebaseCrashlytics-Unit-unit scheme and press Command-u.

If the crash report proto needs to be updated, follow these instructions:

• Update ProtoSupport/Protos/crashlytics.proto with the new changes
• Depending on the type of fields added/removed, also update ProtoSupport/Protos/crashlytics.options. CALLBACK type fields in crashlytics.nanopb.c needs to be changed to POINTER (through the options file). Known field types that require an entry in crashlytics.options are strings, repeated and bytes.
• Run generate_project.sh to update the nanopb .c/.h files.
