1. git clone https://github.com/NYPL-Simplified/Simplified-iOS.git or git clone [email protected]:NYPL-Simplified/Simplified-iOS.git
2. cd Simplified-iOS
3. git submodule update --init --recursive
4. Install Carthage if you haven't already.
5. carthage bootstrap --platform ios --use-ssh. Note: If carthage bootstrap fails, you may need to create an installer package from our fork: https://github.com/NYPL-Simplified/Carthage.
6. Symlink the unzipped "DRM_Connector_Prerelease" directory to "adobe-rmsdk" within the "Simplified-iOS" directory. (You will need to have obtained this binary from Adobe.)
7. Build OpenSSL and cURL as described in the following "Building OpenSSL and cURL" section. Ensure you're in the "Simplified-iOS" directory before continuing to the next step.
8. sh adobe-rmsdk-build.sh
9. (cd readium-sdk; sh MakeHeaders.sh Apple) (parentheses included) to generate the headers for Readium.
10. cp APIKeys.swift.example Simplified/APIKeys.swift and edit accordingly.
11. cp Accounts.json.example Simplfiied/Accounts.json.
12. open Simplified.xcodeproj
13. Build.

Follow the instructions in "adobe-rmsdk/RMSDK_User_Manual(obj).pdf" to build OpenSSL (section 12.1) and cURL (section 12.3). Be sure to note the following:

• You will need to verify and edit the "build.sh" scripts for both OpenSSL and cURL to reflect the correct version numbers and local directory names (lines 11–24).
• You must add --enable-ipv6 to line 80 of Adobe's "build.sh" script used for building cURL. This necessary both due to Apple's requirements for IPv6 support and because the library may not build against recent iOS SDKs otherwise.
• cURL 7.57.0 is known not to work and later versions are unlikely to work either. 7.50.0 is recommended.

Note: This configuration is not currently supported. In the interim, you should be able to get it to build via the following steps:

1. git clone https://github.com/NYPL-Simplified/Simplified-iOS.git or git clone [email protected]:NYPL-Simplified/Simplified-iOS.git
2. cd Simplified-iOS
3. git submodule deinit adept-ios && git rm -rf adept-ios
4. git submodule deinit adobe-content-filter && git rm -rf adobe-content-filter
5. git submodule update --init --recursive
6. Install Carthage if you haven't already.
7. Remove "NYPL-Simplified/NYPLAEToolkit" and "AudioEngine.json" in Cartfile and Cartfile.resolved.
8. carthage bootstrap --platform ios --use-ssh
9. cp APIKeys.swift.example Simplified/APIKeys.swift and edit accordingly.
10. cp Accounts.json.example Simplified/Accounts.json.
11. (cd readium-sdk; sh MakeHeaders.sh Apple) (parentheses included) to generate the headers for Readium.
12. open Simplified.xcodeproj
13. Remove import of "Simplified+RMSDK.xcconfig" from "Simplified.xcconfig".
14. Delete NYPLAEToolkit.framework and AudioEngine.framework from "Link Binary with Libraries", and remove input and output filepaths for AudioEngine.framework and NYPLAEToolkit.framework from Copy Frameworks (Carthage).
15. Note: For now, we recommend keeping any unstaged changes as a single git stash until better dynamic build support is added.
16. Build.

This codebase follows Google's Objective-C Style Guide including the use of two-space indentation. Both Objective-C and Swift may be used for new code.

The primary services/singletons within the program are as follows:

• NYPLAccount
• NYPLBookCoverRegistry (used directly only by NYPLBookRegistry)
• NYPLBookRegistry
• NYPLConfiguration
• NYPLKeychain
• NYPLMyBooksDownloadCenter

All of the above contain appropriate documentation in the header files.

The rest of the program follows Apple's usual pattern of passive views, relatively passive models, and one-off controllers for integrating everything. Immutability is preferred wherever possible.
