New SDK & Documentation Site
JB4A SDK for iOS is deprecated as of January, 2018.

Use the New Documentation and Repository Site

The June 2019 release of the MobilePush SDK (6.3.x or higher) will be hosted on (https://salesforce-marketingcloud.github.io/MarketingCloudSDK-iOS/). To ensure that you are using our latest SDK and are prepared for future releases, we recommend that you migrate your build script now to point to the new repository.
