Objective-C SDK

This repository houses the Objective-C SDK for use with Optimizely Full Stack and Optimizely Rollouts for Mobile and OTT.

Optimizely Full Stack is A/B testing and feature flag management for product development teams. Experiment in any application. Make every feature on your roadmap an opportunity to learn. Learn more at https://www.optimizely.com/platform/full-stack/, or see the documentation.

Optimizely Rollouts is free feature flags for development teams. Easily roll out and roll back features in any application without code deploys. Mitigate risk for every feature on your roadmap. Learn more at https://www.optimizely.com/rollouts/, or see the documentation.

Getting Started

NOTE

For new and upgrading iOS users, it's recommended to use our new Swift-SDK written completely in Swift. The Swift SDK will serve as our primary iOS SDK for new development moving forward. It is functionally compatible with the Objective-C SDK and provides an extended feature set with simplified interfaces.

Existing Objective-C SDK users can look at our guide document for migrating into the new Swift SDK.

Using the SDK

See Install the iOS and tvOS SDKs to learn how to set up an Optimizely X project and start using the SDK.

Requirements

• iOS 8.0+ / tvOS 9.0+

Installing the SDK

Please note below that <platform> is used to represent the platform on which you are building your app. Currently, we support iOS and tvOS platforms.

**note: if you or another framework are using sqlite, then you should probably add compiler options for thead safe sqlite: SQLITE_THREADSAFE=1 https://www.sqlite.org/threadsafe.html

Cocoapod

1. Add the following lines to the Podfile:

   use_frameworks!
   pod 'OptimizelySDK<platform>', '~> 3.1.5'

2. Run the following command:

   pod install

Further installation instructions for Cocoapods: https://guides.cocoapods.org/using/getting-started.html

Carthage

1. Add the following lines to the Cartfile:

   github "optimizely/objective-c-sdk" ~> 3.1.5

2. Run the following command:

   carthage update

3. Link the frameworks to your project. Go to your project target's Link Binary With Libraries and drag over the following from the Carthage/Build/<platform> folder:

   OptimizelySDKCore.framework
   OptimizelySDKDatafileManager.framework
   OptimizelySDKEventDispatcher.framework
   OptimizelySDKShared.framework
   OptimizelySDKUserProfileService.framework
   OptimizelySDK<platform>.framework

4. To ensure that proper bitcode-related files and dSYMs are copied when archiving your app, you will need to install a Carthage build script:

   • Add a new Run Script phase in your target's Build Phase.
     
   • In the script area include:

     /usr/local/bin/carthage copy-frameworks

   • Add the paths to the frameworks to the Input Files list:

     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDKCore.framework
     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDKDatafileManager.framework
     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDKEventDispatcher.framework
     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDKShared.framework
     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDKUserProfileService.framework
     $(SRCROOT)/Carthage/Build/<platform>/OptimizelySDK<platform>.framework

   • Add the paths to the copied frameworks to the Output Files list:

     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDKCore.framework
     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDKDatafileManager.framework
     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDKEventDispatcher.framework
     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDKShared.framework
     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDKUserProfileService.framework
     $(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/OptimizelySDK<platform>.framework

Manual Installation

The universal framework can be used in an application without the need for a third-party dependency manager. The universal framework packages up all Optimizely X Mobile modules, which include:

OptimizelySDKCore
OptimizelySDKShared
OptimizelySDKDatafileManager
OptimizelySDKEventDispatcher
OptimizelySDKUserProfileService

The universal framework for iOS includes builds for the following architectures:

i386
x86_64
ARMv7
ARMv7s
ARM64

The universal framework for tvOS includes builds for the following architectures:

x86_64
ARM64

Bitcode is enabled for both the iOS and tvOS universal frameworks.

In order to install the universal framework, follow the steps below:

1. Download the iOS or tvOS framework.

2. Unzip the framework, then drag the framework to your project in Xcode; Xcode should prompt you to select a target. Go to Build Phases and make sure that the framework is under the Link Binary with Libraries section.

3. Go to the General tab and add the framework to the Embedded Binaries section. If the Embedded Binaries section is not visible, add the framework in the Copy Files section (you can add this section in Build Settings).

4. The Apple store will reject your app if you have the universal framework installed as it includes simulator binaries. Therefore, a script to strip the extra binaries needs to be run before you upload the app. To do this, go to Build Phases and add a Run Script section by clicking the + symbol. Copy and paste the following script (make sure you replace the FRAMEWORK_NAME with the proper framework name! ):

   FRAMEWORK="FRAMEWORK_NAME"
   FRAMEWORK_EXECUTABLE_PATH="${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/$FRAMEWORK.framework/$FRAMEWORK"
   EXTRACTED_ARCHS=()
   for ARCH in $ARCHS
   do
      lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o "$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
      EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
   done
   lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create "${EXTRACTED_ARCHS[@]}"
   rm "${EXTRACTED_ARCHS[@]}"
   rm "$FRAMEWORK_EXECUTABLE_PATH"
   mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"
   

If you choose to build the universal framework yourself, you can do so by running the OptimizelySDKiOS-Universal or OptimizelySDKTVOS-Universal schemes. After building these schemes, the frameworks are output in the OptimizelySDKUniversal/generated-frameworks folder.
