### Todos

- [ ] Improve readme by adding examples and simplifying descriptions.

- [ ] Add LocalAuthenticationClient [ _Soon_ ]

- [ ] Find out if it's better to use `Any`-based UserDefaults storage instead of `DataRepresentable`-based.

- Add more tests

  - [ ] Caching

  - [ ] IDFA

  - [ ] Keychain

  - [ ] Notifications

  - [ ] HapticEngine

  - [ ] UserDefaults

  - [x] DataRepresentable

## Caching

`CacheClient` is a generic client over hashable key and value, it provides interfaces for the following operations:

- `saveValue(_: Value, forKey: Key)`

- `loadValue(of: Value.Type = Value.self, forKey: Key) -> Value`

- `removeValue(forKey: Key)`

- `removeAllValues()`

#### MemoryCacheClient

`MemoryCacheClient` is build on top of `NSCache`. Under the hood it uses `MemoryCache` wrapper, improved version of [John Sundells' Cache](https://www.swiftbysundell.com/articles/caching-in-swift/). You can use `MemoryCache` (which also provides a way to save itself to disk if your types are codable) directly to build your own `CacheClient` implementations.

## IDFA

`IDFAPermissionClient` is a client for `ASIdentifierManager` and `ATTrackingManager`, it provides interfaces for the following operations:

- `requestAuthorizationStatus() -> AnyPublisher`

- `requestAuthorization() -> AnyPublisher`

- `requestIDFA() -> AnyPublisher`

> `IDFAPermissionClient.AuthorizationStatus` is a wrapper for `ATTrackingManager.AuthorizationStatus` type and `ASIdentifierManager.isAdvertisingTrackingEnabled` value it's values are:

>

> - `notDetermined = "Not Determined"`  `// ATTrackingManager.AuthorizationStatus.notDetermined`

> - `restricted = "Restricted"` `// ATTrackingManager.AuthorizationStatus.restricted`

> - `denied = "Denied"` `// ATTrackingManager.AuthorizationStatus.denied`

> - `authorized = "Authorized"` `// ATTrackingManager.AuthorizationStatus.authorized`

> - `unknown = "Unknown"` `// ATTrackingManager.AuthorizationStatus.unknown`

> - `unavailableWithTrackingEnabled = "Unavailable: Tracking Enabled"` `// iOS<14 macOS<11, tvOS<14 ASIdentifierManager.shared().isAdvertisingTrackingEnabled == true`

> - `unavailableWithTrackingDisabled = "Unavailable: Tracking Disabled"` `// iOS<14 macOS<11, tvOS<14 ASIdentifierManager.shared().isAdvertisingTrackingEnabled == false`

>

> It also has a computed property `isPermissive` which is `true` for `.authorized` and `.unavailableWithTrackingEnabled`

## Keychain

`KeychainClient` is a client for Security framework keychain access, it **stores objects as data** (Using [`DataRepresentable`](#DataRepresentable) protocol) and provides interfaces for the following operations:

- `saveValue(_: Value, forKey: Key, policy: AccessPolicy)`

- `loadValue(of: Value.Type = Value.self, forKey: Key) -> Value`

- `removeValue(forKey: Key)`

`KeychainClient.Key` can be initialized by `rawValue: Stirng`, `StringLiteral` or `StringInterpolation`. Also you can use `.bundle(_:Key)` or `.bundle(_:Bundle, _:Key)`  to add `bundleID` prefix to your key.

> `KeychainClient.Operations.Save.AccessPolicy` is a wrapper for kSec access constants and it's values are:

>

> - `accessibleWhenUnlocked` `// kSecAttrAccessibleWhenUnlocked`

> - `accessibleWhenUnlockedThisDeviceOnly` `// kSecAttrAccessibleWhenUnlockedThisDeviceOnly`

> - `accessibleAfterFirstUnlock` `// kSecAttrAccessibleAfterFirstUnlock`

> - `accessibleAfterFirstUnlockThisDeviceOnly` `// kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly`

> - `accessibleWhenPasscodeSetThisDeviceOnly` `// kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly`

> - `accessibleAlways` `// kSecAttrAccessibleAlways`

> - `accessibleAlwaysThisDeviceOnly` `// kSecAttrAccessibleAlwaysThisDeviceOnly`

>

## Notifications

`NotificationsPermissionsClient` is a client for `UNUserNotificationCenter`, it provides interfaces for the following operations:

- `requestAuthorizationStatus() -> AnyPublisher`

- `requestAuthorization(options: AuthorizationOptions) -> AnyPublisher`

- `configureRemoteNotifications(_:)` // Pass `.register` or `.unregister` to the function

> `NotificationsPermissionsClient.AuthorizationStatus` is a wrapper for `UNAuthorizationStatus` type it's values are:

>

> - `notDetermined`

>

> - `denied`

>

> - `authorized`

>

> - `provisional`

>

> - `ephemeral` `// iOS14+ only`

>

> It also has a computed property `isPermissive` which is true for `authorized`, `ephimeral` and `provisional`

> `NotificationsPermissionsClient.AuthorizationOptions` is a wrapper for `UNAuthorizationOptions` type it's predefined values are:

>

> - `badge`

> - `sound`

> - `alert`

> - `carPlay`

> - `criticalAlert`

> - `providesAppNotificationSettings`

> - `provisional`

> - `announcement` `// iOS only`

>

> You can also construct `AuthorizationOptions` object by providing `UInt` raw value. 

## HapticEngine

`HapticEngineClient` is a factory-client for `HapticFeedback` clients. `HapticFeedback` is a client for `UIFeedbackGenerator`.

### Usage

```swift

import HapticEngineClientLive

// If you need just one generator you can use HapticFeedback directly

HapticFeedback.success.trigger()

// Otherwise if you need more flexible way to create Haptic feedbacks use HapticEngineClient

HapticEngineClient.live.generator(for: .success).trigger()

```

## UserDefaults

`UserDefaultsClient` is a client for UserDefaults object, it **stores objects as data** (Using [`DataRepresentable`](#DataRepresentable) protocol) and provides interfaces for the following operations:

- `saveValue(_: Value, forKey: Key)`

- `loadValue(of: Value.Type = Value.self, forKey: Key) -> Value`

- `removeValue(forKey: Key)`

`UserDefaultsClient.Key` can be initialized by `rawValue: Stirng`, `StringLiteral` or `StringInterpolation`. Also you can use `.bundle(_:Key)` or `.bundle(_:Bundle, _:Key)`  to add `bundleID` prefix to your key.

## DataRepresentable

[`DataRepresentable`](Sources/DataRepresentable) module provides a protocol for objects data representation. It is used by `UserDefaultsClient` and `KeychainClient` to store objects as data.

## Installation

### Basic

You can add StandardClients to an Xcode project by adding it as a package dependency.

1. From the **File** menu, select **Swift Packages › Add Package Dependency…**

2. Enter [`"https://github.com/capturecontext/swift-standard-clients.git"`](https://github.com/capturecontext/swift-standard-clients.git) into the package repository URL text field

3. Choose products you need to link them to your project.

### Recommended

If you use SwiftPM for your project, you can add StandardClients to your package file.

```swift

.package(

  name: "swift-standard-clients",

  url: "https://github.com/capturecontext/swift-standard-clients.git", 

  .upToNextMinor(from: "0.1.0")

)

```

Do not forget about target dependencies:

```swift

.product(

  name: "SomeClientOrClientLive", 

  package: "swift-standard-clients"

)

```
