superwall/Superwall-iOS 3.2.0 on GitHub

Adds user.seed to user attributes for use in campaign rules. This assigns a user a random number from 0 to 99. This allows you to segment users into cohorts across campaigns. For example, in campaign A you may say if user.seed < 50 { show variant A } else { show variant B }, in campaign B you may say if user.seed < 50 { show variant X } else { show variant Y }. Therefore users who see variant A will then see variant X.
Adds ability to use device.interfaceType in campaign rules to show different paywalls for different interface types. Use this instead of device.deviceModel, as that can lead to inaccurate results on some devices. interfaceType can be one of ipad/iphone/mac/carplay/tv/unspecified. Note that iPhone screen size emulated in iPad will be iphone. Built for iPad on Mac will be ipad.
Adds presentation_source_type to PaywallInfo, which lets you know the source function that retrieved the paywall – register/getPaywall/implicit.
Tracks whether a purchase controller is being used on the AppInstall event.

Fixes issue where the transition from background to foreground may not have been detected on app launch, resulting in paywalls not showing.
Fixes iOS 14 transaction validation issue that affects apps on v3.0.2+.
Adds safeguard for developers returning an empty NSError on purchase failure which could cause a crash.
