Fixes Same-Version Update Bug

• #288: It was discovered that Siren would prompt the user with an update if the same version of the app was installed that also happened to be the latest version of the app. This was due to an improper handling of that specific case. This is now fixed in #289. Thanks to @ergunkocak for pointing out this bug!

Fixes to DateExtension

#283/#284: Fixes a date calculation mistake on the DateExtension (thanks to @fahlout)

Siren v5 (+ Swift 5 Support)

• Adds Swift 5 Support (#277)
• Implements Swift 5's Result type in Siren.swift and APIManager.swift
• Renames LookupModel.swift to APIModel.swift
• Exposes all values in APIModel.swift in a nice public API on a new struct, Model.swift. (#276)
• Siren's public completion handler now uses the Result type and returns Model.swift instead of APIModel.swift
• Fixes the placement of the Update button on .optional alerts (#278)

If you still need access to the Swift 4.2 version of Siren, please use the swift4.2 branch which is equivalent to Siren v4.2.2.

Fixed Imports

• #273: Replaces some Foundation imports with UIKit imports to fix Xcode project generation issues with Bazel. Thanks @thii

Simplified Add/Remove Observer Methods

Just some method name changes and code consolidated in Siren.swift around methods dealing with observers. Specific changes can be found here: df6174b#diff-2e790de59976a9805984bb04ac1314d7

Fixed Skip Alert Action Logic

• #270: The skip action had improper conditional logic leading to skip mimicking the next time logic, instead of actually respecting the end-user's preferences. This has now been fixed. (thanks @nixnoughtnothing)

Result Type Changes and Documentation Improvements

• Results.localization is now a let
• Results.lookupModel is now a let
• Improved documentation in multiple places and regenerated documentation for https://sabintsev.com/Siren

Multiple Bugfixes and Improvements

• #265 (thanks @erichsu/@BelfDev): Adds a new enum, PerformCheck, that is used in the wail method to allow a developer to select if Siren should performa version check when the app enters the foreground state or have it trigger manually when the wail method is called.

• #267 (thanks @mmdock/@antoinepemeja): Fixes an alert stacking issue when a user uses UpdatePromptFrequency.immediately and the user enters the app switcher before entering the app again.

• #269 (thanks @mmdock): Adds a new built in version checking and presentation rule

  • Rules(promptFrequency: .weekly, forAlertType: .option)

Fixes "Next Time" Prompt Bug

• #264: Fixes #258 by removing the shouldPerformVersionCheckOnSubsequentLaunch UserDefault. This was done to fix the Next Time action causing the version check alert from appearing every single time a consuming app is launched from the background, irrespective of what rules were in place within RulesManager.

Documentation was also updated.

Quality of Life Bugfixes

• Fixes alerts being layered on top of each other when the consuming app is backgrounded by adding a didEnterBackgroundNotification observer.
• Changes PresentationManager's alertController variable from private to internal to provide Siren.swift access to this variable. This may get moved into PresentationManager in a future update.
• Adds missing documentation to wail method.
• Other minor changes to how code is ordered in Siren.swift

Thanks to @kamrankhan07 for his extensive testing of Siren v4.0.0 and for finding the the alert layering issue.
