4.0.0

[4.0.0] - 2019-04-18

This is the first non-beta release of the Swift SDK. It follows the beta.3 release from 2019-03-07. Unlike previous Swift SDK releases, this release does not have a 3.0.0 companion tag.

Changed

• Changes Feature Flag caching so that cached feature flags are associated with a user key and mobile key.
• Clears new warnings that appear with Xcode 10.2

Added

• Implements URL caching for REPORT requests.
• Installs the ability to read cached data in all cached data schemas from 2.3.3 through 3.0.1 and store the feature flags in the 4.0.0 cached data schema.
• Retains prior cached data for 90 days following upgrade to 4.0.0. Does not keep older cached data up-to-date. Downgrading to a prior version within 90 days allows the downgraded app to read the last cached data from the downgraded version.

Fixed

• Prevents a log message that incorrectly reported a network error on watchOS
