# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [7.0.0] - 2024-05-14
### Added
- Added Privacy Manifest to Swift package.
### Changed
- Bumped platform targets in `Package.swift` from iOS/tvOS 9 -> 12 and macOS 10_10 -> 10_13.
	- Also updated in `Connectivity.podspec`.

## [6.1.1] - 2023-09-23
### Changed
- Added the `connectivityURLs` property back as this was a breaking change see [issue #78](https://github.com/rwbutler/Connectivity/issues/78).

## [6.1.0] - 2023-09-12
### Added
- `Connectivity` property `connectivityURLs: [URL]` swapped to `connectivityURLRequests: [URLRequest]`. The framework now uses `URLRequest` primarily throughout. Suggestion by [@brunomiguens](https://github.com/BrunoMiguens) - [https://github.com/rwbutler/Connectivity/issues/67](https://github.com/rwbutler/Connectivity/issues/67). 
- `URLRequest` objects used for connectivity checks may not be configured via configuration initialiser or via the fluent configuration API e.g. 
	- ```swift
	ConnectivityConfiguration()
	.configureConnectivity(urlRequests: [
	    URLRequest(...)
	])
	```
- `URL` objects may still be used rather than `URLRequesd` objects via the fluent configuration API only e.g.
	- ```swift
	ConnectivityConfiguration()
	.configureConnectivity(urls: [
	    URL(...)
	])
	```
	
### Changed
- Changed the default framework used to monitor network interface changes to `.network`. To continue using the System Configuration (Apple's Reachability) framework for monitoring network interface changes set the `framework` property to `.systemConfiguration`.
- Fixed a typo in `ConnectivityConfiguration`. `validationMode` was incorrectly spelt as `validatioMode`.

## [6.0.0] - 2023-03-09
### Added
- Added ability to set the authorization header to be used when contacting an endpoint (thanks to  [Nils Bergmann](https://github.com/TheNoim) - see [https://github.com/rwbutler/Connectivity/pull/73](https://github.com/rwbutler/Connectivity/pull/73)).

### Changed
- iOS deployment target updated to iOS 11.0 (dropped support for iOS 9.0 and 10.0 in-line with Xcode 14).
- macOS deployment target updated to macOS 10.13.
- Fixed being unable to set `bearerToken`, `framework` and `validationMode` using the configuration object (thanks to  [Nils Bergmann](https://github.com/TheNoim) - see [https://github.com/rwbutler/Connectivity/pull/73](https://github.com/rwbutler/Connectivity/pull/73)).

## [5.3.1] - 2022-07-29
### Changed
Applied Carthage fix - see: [https://github.com/rwbutler/Connectivity/pull/66](https://github.com/rwbutler/Connectivity/pull/66) and [https://github.com/rwbutler/Connectivity/issues/65](https://github.com/rwbutler/Connectivity/issues/65).

## [5.3.0] - 2022-05-15
### Added
A Connectivity publisher now accepts a configuration object which can be used to configure the framework.

```swift
let publisher = Connectivity.Publisher(
    configuration:
					.init()
          .configureURLSession(.default)
)
```

## [5.2.0] - 2022-05-14
### Added
- Fluent configuration API: Connectivity may now be configured by passing a `ConnectivityConfiguration` object to the initializer.
### Changed
- Internal `DispatchQueue` used by the framework now uses `.default` QOS rather than `.background`.

## [5.1.1] - 2022-05-13
### Changed
- Updated to Xcode 13.3.1 and resolved warnings.

## [5.1.0] - 2021-07-30
### Added
- Support for determining connection state of Ethernet connections.

### Changed
- Support compilation under Xcode 12.5.1.
- OHHTTPStubs 8.0.0 -> 9.1.0 for testing
- Updated documentation in README.md
- Headers search path added to Package.swift with thanks to @larryonoff

## [5.0.0] - 2020-09-15
### Added
- Support for Xcode 12.

### Changed
- Dropped support for iOS 8

## [4.2.0] - 2020-08-08
### Added
- Support for macOS.

### Changed
- Fixes Swift Package Manager integration.

## [4.1.0] - 2020-07-07
### Added
- Added `checkWhenApplicationDidBecomeActive` flag which when enabled will check connectivity status when an app returns from the background.
- Added `pollWhileOfflineOnly` flag which ensures that Connectivity only polls after recording an unsuccessful connection result. Following a successful result polling will cease.

### Changed
- The entirety of the logic that was previously in `checkConnectivity` is now offloaded to `internalQueue` immediately.
- Where polling, it was possible for a successful connection check to not be able to report the network interface used (as Reachability returned `NotReachable`) where using the `.systemConfiguration` framework option. In this instance, Connectivity now uses `NWPathMonitor` as a fallback on iOS 12+ even where `.systemConfiguration` is the selected option.

## [4.0.0] - 2020-05-05
### Added
- `Connectivity.Publisher` introduced providing support for Combine in iOS 13.0.

## [3.3.4] - 2020-04-21
### Changed
- Lowered the default connectivity threshold to 50% as it was recently reported that in certain parts of the world the recently added iOS 13 connectivity URL is inaccessible causing an offline result to be returned with the previous default threshold of 75% and only the two example connectivity URLs used. See [issue #41](https://github.com/rwbutler/Connectivity/issues/41).

## [3.3.3] - 2019-11-18
### Changed
- Added iOS 13 URL to default connectivity URLs.

## [3.3.2] - 2019-11-14
### Changed
- Made `ConnectivityStatus` enum Objective-C compatible.

## [3.3.1] - 2019-11-13
### Changed
- Made `ConnectivityFramework` enum Objective-C compatible.

## [3.3.0] - 2019-11-04
### Added
- Added new validators including:

	- `ConnectivityResponseStringEqualityValidator`: Determines whether the response string is equal to an expected string.
	- `ConnectivityResponseContainsStringValidator`: Determines whether the response string contains an expected string.
	- `ConnectivityResponseRegExValidator`: Determines whether the response string matches a given regular expression.

These validators can be composed when creating a custom validator conforming to `ConnectivityResponseValidator` protocol.

## [3.2.0] - 2019-10-22
### Added
- Property `validationMode` on the Connectivity object may now take a value of `.custom` allowing an implementation of `ConnectivityResponseValidator` protocol to be supplied to the `responseValidator` property. This custom validator will be used to validate the response returned when accessing the connectivity URLs.

## [3.1.2] - 2019-10-02
### Changed
- Updated podspec to include `Network.framework` as part of the `weak_frameworks` entry rather than as part of `frameworks`.

## [3.1.1] - 2019-09-03
### Changed
- Fixed missing framework dependencies in podspec, see [Issue #24](https://github.com/rwbutler/Connectivity/issues/24).

## [3.1.0] - 2019-08-08
### Added
- Properties `availableInterfaces` and `currentInterface` indicate the network interfaces used in the most recent connectivity check.
- New `Connectivity.Status` case `.determining` will be returned prior to a connectivity check having completed.
### Changed
- Refactor of `status` property which is now set on most recent connectivity check rather than computed on read.

## [3.0.4] - 2019-08-01
### Changed
- Ensure reading from and writing to the `path` property occurs in a thread-safe manner.

## [3.0.3] - 2019-08-01

## [2.0.1] - 2019-01-02
### Changed
- Enabled `Allow app extension API only` in target deployment info.

## [2.0.0] - 2018-12-09
### Added
- Provided the ability to switch between Reachability and the Network framework (from iOS 12 onwards) using the new `framework` property on the `Connectivity` object. 
### Changed
- Makes a `checkConnectivity` call required to reliably query connectivity state for one-off checks (see the example app).
- Properties referring to `WWAN` have been renamed to `Cellular` e.g. `isConnectedViaWWAN` -> `isConnectedViaCellular`.

## [1.1.1] - 2018-11-23
### Changed
- Refactored code into smaller reusable functions to eliminate code duplication and improve maintainability.

## [1.1.0] - 2018-11-14

## [0.0.1] - 2018-07-27
### Added
- Connectivity is a framework which improves on Reachability by allowing developers to detect whether true Internet connectivity is available or whether a captive portal is blocking Internet traffic.
