Firebase Crashlytics setup on iOS?

If you follow closely the Getting Started documentation, you might be in for some frustrations. Trust me. I had my share of that.

Now here's what I can share with you.

1. If you previously had Fabric RunScript for that Target, then it's best if you delete that and create a new one, apply the GettingStarted instruction, and replace the $(INFOPLIST_PATH) with GoogleService-Info.plist.

2. There should be no Fabric configuration on your Info.plist file anymore. It's this thing: <key>Fabric</key><dict>...</dict>. If you still have that, time to say goodbye and let go of those feelings or face this issue.

3. If you keep seeing this in your Xcode console, [Fabric] failed to download settings Error Domain=FABNetworkError Code=-5... blah blah blah, then go clean that Build Folder first (shift + cmd + k).

If your next build works, try force crashing your app and check out the crash logs on Firebase.

Here's my stack: Xcode 10.2.1 | Fabric 1.9 | Crashlytics 3.12

The issue for me was I was using the old Fabric before and I had to remove the key from my info.plist

I followed the https://fabric.io/kits/ios/crashlytics/install documentation and added the Run Script and updated Info.plist but still got the above issue.

Apparently, I had accidentally added twice 'New Run Script Phase'. After removing the unnecessary 'Run Script's the project compiled successfully.

Xcode 10.1 Fabric 1.7.5 Crashlytics 3.10.4

Documentation

• if crashlytics is already set up in your project (in case of migration),

  1. Remove the fabric key from Info.plist (need to remove the dictionary and the key for Fabric)
  2. Follow the documentation.(just need to use "${PODS_ROOT}/Fabric/run", instead of "${PODS_ROOT}/Fabric/run" key1 key2 in the Run script under build phase)

• if crashlytics is not setup in your project already(starting a fresh integration with firebase crashlytics), simply follow the documentation.

If you're using Crashlytics, you might have to go into your Build Phases -> Crashlytics configuration and add it into the shell/bin/sh section like this: `set -e

if [[ ${PODS_ROOT} ]]; then echo "info: Exec Fabric Run from Pods" "${PODS_ROOT}/Fabric/run" YOUR KEY HERE else echo "info: Exec Fabric Run from framework" "${PROJECT_DIR}/Fabric.framework/run" YOUR KEY HERE fi`

Alternative script

1. Go to "Build Phases"
2. Create a new script in + -> "NewRun Script Phase"
3. Chech that it's always the last one
4. Copy and Past this script

set -e

echo "info: Exec Upload dSYM"
#Path for google service .plist 
GOOGLE_SERVICE_INFO_PLIST="${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME}/GoogleService-Info.plist"
#Path for DSYM directory
DSYM_PATH="$DWARF_DSYM_FOLDER_PATH/dddd/$DWARF_DSYM_FILE_NAME"
#Firebase command script
CMD=""
if [[ ${PODS_ROOT} ]]; then
  echo "info: Exec FirebaseCrashlytics Run from Pods"
  CMD="$PODS_ROOT/FirebaseCrashlytics/upload-symbols"
else
  echo "info: Exec FirebaseCrashlytics Run from framework"
  CMD="$PROJECT_DIR/FirebaseCrashlytics.framework/upload-symbols"
fi

echo "info: Checking if .plist exists"
if [ -f "$GOOGLE_SERVICE_INFO_PLIST" ]; then
    echo "info: $GOOGLE_SERVICE_INFO_PLIST exists."
else 
    echo "ERROR: $GOOGLE_SERVICE_INFO_PLIST does not exist."
    exit 1
fi

echo "info: Checking if .dSYM"
if [ -d "$DSYM_PATH" ]; then
    echo "info: $DSYM_PATH exists."
else 
    echo "ERROR: $DSYM_PATH does not exist."
    echo "info: try fallback"
    DSYM_PATH=` find "${DWARF_DSYM_FOLDER_PATH}" -name "*.dSYM" | xargs `
    if [ -d "$DSYM_PATH" ]; then
        echo "info: $DSYM_PATH exists."
    else 
        echo "ERROR: $DSYM_PATH does not exist."
        exit 1
    fi
fi
echo "info: Check if upload-symbols script exists"
if [ -f "$CMD" ]; then
    echo "$CMD exists."
else 
    echo "ERROR: $CMD does not exist."
    exit 1
fi

echo "info: Starting command upload-symbols"
"${CMD}" -gsp "$GOOGLE_SERVICE_INFO_PLIST" -p ios "$DSYM_PATH" > /dev/null 2>&1 &
echo "info: Symbol uploading will proceed in the background."
echo "info: remove '> /dev/null 2>&1 &' to test in the main thread and see if there are any errors, or open console and filter with 'upload-symbols'"
