How to integrate Firebase to iOS app

How to integrate Firebase to iOS?
I see multiple options here: https://firebase.google.com/docs/ios/installation-methods

• Standard pod install
• Swift Package Manager
• Installing from the GitHub repo

But that will not work nice with cmake. What is the recommended way for axmol?

While this isn't an Axmol issue, I've personally tried several methods of integrating Firebase, with the easiest being the Cocoa Pods method. An example Podfile from one of my projects, this one for iOS/arm64, with project name changed:

project './build_ios_arm64/PROJECT_NAME.xcodeproj'

# Uncomment the next line to define a global platform for your project
platform :ios, '15.0'

target 'PROJECT_NAME' do
    inherit! :search_paths
    
    # Comment the next line if you don't want to use dynamic frameworks
    #use_frameworks! :linkage => :static
    use_frameworks!
    
    # Add the Firebase pod for Google Analytics
    pod 'FirebaseAnalytics'

    # Add the pods for any other Firebase products you want to use in your app
    pod 'FirebaseCrashlytics'
end

Run pod init once.

Then, after any update to your Xcode project files, such as via cmake or axmol build commands, re-run pod install --repo-update, and open the PROJECT_NAME.xcworkspace file in Xcode (not the PROJECT_NAME.xcodeproj). That's pretty much it, and as cmake friendly as can be.

We're using Pods so for now we have this setup for CMake:

        # Setup CocoaPods
        add_custom_target(LnPodfile
            COMMAND ${CMAKE_COMMAND} -E create_symlink
                ${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/Podfile
                ${CMAKE_CURRENT_BINARY_DIR}/Podfile
            DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/Podfile
        )
        add_custom_target(LnPodfileLock
            COMMAND ${CMAKE_COMMAND} -E create_symlink
                ${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/Podfile.lock
                ${CMAKE_CURRENT_BINARY_DIR}/Podfile.lock
            DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/Podfile.lock
        )
        add_custom_target(PodInstall
            COMMAND env PATH=\${PATH}:/opt/homebrew/bin LANG=en_US.UTF-8 bash -c \"pod install\"
            WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
            DEPENDS LnPodfile LnPodfileLock
        )

This symlinks proj.ios_mac/Podfile that is in the repo to the build directory, and adds PodInstall target, that you can run from Xcode to run this and instal pods.

The proj.ios_mac/Podfile has this to link to the project:

workspace '../../proj.ios_mac/GmsPlayground' # Adjust this depending to your project name and build path
project 'GmsPlayground'

Hi,

1 - Create the file Podfile.ios in root directory with your content, example:

# Settings
platform :ios, '12.0'
inhibit_all_warnings!
use_frameworks!

# Dependencies
target 'biblemania' do
    # Firebase
    pod 'FirebaseAnalytics'
    pod 'FirebaseCrashlytics'
end

2 - Add at the end of your CMake a command to copy podfile to build directory, example:

# podfile
if(APPLE)
    if(IOS)
        configure_file("${CMAKE_CURRENT_SOURCE_DIR}/Podfile.ios" "${CMAKE_CURRENT_BINARY_DIR}/Podfile" COPYONLY)
    endif()
endif()

3 - Execute axmol build and pod install, example:

rm -rf build_ios_arm64/
axmol build -p ios -a arm64 -c
cd build_ios_arm64 && pod install

4 - Open your xcworkspace file always, example:

open ./build_ios_arm64/biblemania.xcworkspace/

Error in my case when i compile using Xcode:

ld: warning: ignoring duplicate libraries: '-lc++', '/Users/paulo/Developer/workspaces/cpp/biblemania/build_ios_arm64/engine/axmol/core/lib/libaxmol.a'
ld: framework 'Pods_biblemania' not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Can someone help me with this error?

framework 'Pods_biblemania' not found

But it is there:

Thanks.

The solution is:

CMAKE:

if(APPLE)
    if(IOS)
        set_target_properties(${APP_NAME} PROPERTIES XCODE_ATTRIBUTE_CONFIGURATION_BUILD_DIR "\${BUILD_DIR}/\$(CONFIGURATION)\$(EFFECTIVE_PLATFORM_NAME)")
        configure_file("${CMAKE_CURRENT_SOURCE_DIR}/Podfile.ios" "${CMAKE_CURRENT_BINARY_DIR}/Podfile" COPYONLY)
    endif()
endif()

PODFILE:

# Settings
platform :ios, '12.0'

# Dependencies
target 'biblemania' do
    inherit! :search_paths
    #use_frameworks! :linkage => :static # static link
    use_frameworks! # dynamic link

    # Firebase
    pod 'FirebaseAnalytics'
    pod 'FirebaseCrashlytics'
end

FirebaseAnalytics is not working in mine..
Others are working..

I have pod like this:

target 'LudoX' do
  inherit! :search_paths
  use_frameworks!
  # Pods for LudoX
    pod 'FirebaseAnalytics'    
    pod 'FirebasePerformance'
    pod 'FirebaseCrashlytics'
    pod 'FirebaseRemoteConfig'
    pod 'GoogleUserMessagingPlatform'
    pod 'Google-Mobile-Ads-SDK'
end

FIRAnalytics is not working.. I'm getting this error:

Use of undeclared identifier 'FIRAnalytics'

But FirebaseAnalytics folder is there in pods. I tried cleaning/rebuilding but it didn't work.
