5.2.0

Added

• LDUser now has an optional secondary attribute to match other LaunchDarkly SDKs. For more on the behavior of this attribute see the documentation on targeting users.

Fixed

• Corrected a bug preventing private custom attribute names being recorded in events when all custom attributes are set to be private by including "custom" in the LDUser.privateAttributes or LDConfig.privateUserAttributes properties.
• Update Nimble to 9.0 and Quick to 3.0 to fix tests when run with Swift 5.3.
• Fixes build warnings in Xcode 12.0.0.
