ZamzamKit

ZamzamKit is a Swift package for rapid development using a collection of micro utility extensions for Standard Library, Foundation, and other native frameworks.

Installation

Swift Package Manager

.package(url: "[email protected]:ZamzamInc/ZamzamKit.git", .upToNextMajor(from: "5.1.0"))

The ZamzamKit package contains four different products you can import. Add any combination of these to your target's dependencies within your Package.swift manifest:

.target(
    name: "MyAppExample",
    dependencies: [
        .product(name: "ZamzamCore", package: "ZamzamKit"),
        .product(name: "ZamzamLocation", package: "ZamzamKit"),
        .product(name: "ZamzamNotification", package: "ZamzamKit"),
        .product(name: "ZamzamUI", package: "ZamzamKit"),
    ]
)

Note: This library is highly volatile and changes often to stay ahead of cutting-edge technologies. It is recommended to copy over code that you want into your own libraries or fork it.

ZamzamCore

Standard+

Collection

Get distinct elements from an array:

[1, 1, 3, 3, 5, 5, 7, 9, 9].distinct // [1, 3, 5, 7, 9]

Remove an element from an array by the value:

var array = ["a", "b", "c", "d", "e"]
array.remove("c")
array // ["a", "b", "d", "e"]

Easily get the array version of an array slice:

["a", "b", "c", "d", "e"].prefix(3).array

Safely retrieve an element at the given index if it exists:

// Before
if let items = tabBarController.tabBar.items, items.count > 4 {
    items[3].selectedImage = UIImage("my-image")
}

// After
tabBarController.tabBar.items?[safe: 3]?.selectedImage = UIImage("my-image")

[1, 3, 5, 7, 9][safe: 1] // Optional(3) [1, 3, 5, 7, 9][safe: 12] // nil

> Determine if a value is contained within the array of equatable values:
```swift
"b".within(["a", "b", "c"]) // true

let status: OrderStatus = .cancelled
status.within([.requested, .accepted, .inProgress]) // false

Dictionary

Convert to JSON string or data:

// Before
guard let data = try? JSONSerialization.data(withJSONObject: merged, options: []),
    let log = String(data: data, encoding: .utf8) else {
        return
}

// After guard let log = merged.jsonString else { return }

</details>

<details>
<summary>Number</summary>

> Round doubles, floats, or any floating-point type:
```swift
123.12312421.rounded(toPlaces: 3) // 123.123
Double.pi.rounded(toPlaces: 2) // 3.14

String

Create a new random string of given length:

String(random: 10) // "zXWG4hSgL9"
String(random: 4, prefix: "PIN-") // "PIN-uSjm"

Safely use subscript indexes and ranges on strings:

let value = "Abcdef123456"
value[3] // "d"
value[3..<6] // "def"
value[3...6] // "def1"
value[3...] // "def123456"
value[3...99] // nil
value[99] // nil

Validate string against common formats:

"[email protected]".isEmail // true
"123456789".isNumber // true
"zamzam".isAlpha // true
"zamzam123".isAlphaNumeric // true

Remove spaces or new lines from both ends:

" Abcdef123456 \n\r  ".trimmed // "Abcdef123456"

Truncate to a given number of characters:

"Abcdef123456".truncated(3) // "Abc..."
"Abcdef123456".truncated(6, trailing: "***") // "Abcdef***"

Determine if a given value is contained:

"1234567890".contains("567") // true
"abc123xyz".contains("ghi") // false

Injects a separator every nth characters:

"1234567890".separated(every: 2, with: "-") // "12-34-56-78-90"

Remove the characters contained in a given set:

let string = """
    { 0         1
    2                  34
    56       7             8
    9
    }
    """

string.strippingCharacters(in: .whitespacesAndNewlines) // {0123456789}

> Replace the characters contained in a given character set with another string:
```swift
let set = CharacterSet.alphanumerics
    .insert(charactersIn: "_")
    .inverted

let string = """
    _abcdefghijklmnopqrstuvwxyz
    ABCDEFGHIJKLMNOPQRSTUVWXYZ
    0{1 2<3>[email protected]#6`7~8?9,0

    1
    """

string.replacingCharacters(in: set, with: "_") //_abcdefghijklmnopqrstuvwxyz_ABCDEFGHIJKLMNOPQRSTUVWXYZ_0_1_2_3_4_5_6_7_8_9_0__1

Match using a regular expression pattern:

"1234567890".match(regex: "^[0-9]+?$") // true
"abc123xyz".match(regex: "^[A-Za-z]+$") // false

Replace occurrences of a regular expression pattern:

"aa1bb22cc3d888d4ee5".replacing(regex: "\\d", with: "*") // "aa*bb**cc*d***d*ee*"

Remove HTML for plain text:

"<p>This is <em>web</em> content with a <a href=\"http://example.com\">link</a>.</p>".htmlStripped // "This is web content with a link."

Encoders and decoders:

value.urlEncoded()
value.urlDecoded()
value.htmlDecoded()
value.base64Encoded()
value.base64Decoded()
value.base64URLEncoded()

Get an encrypted version of the string in hex format:

"[email protected]".sha256() // 973dfe463ec85785f5f95af5ba3906eedb2d931c24e69824a89ea65dba4e813b

Easily get the string version of substring:

"hello world".prefix(5).string

Determine if an optional string is nil or has no characters

var value: String? = "test 123"
value.isNilOrEmpty

Foundation+

Bundle

Get the string from a file within any bundle:

Bundle.main.string(file: "Test.txt") // "This is a test. Abc 123.\n"

Get a generic array from a property list file within any bundle:

let values: [String] = Bundle.main.array(plist: "Array.plist")

values[0] // "Abc"
values[1] // "Def"
values[2] // "Ghi"

[Image of BundleArray](./Documentation/Images/BundleArray.png)

let values: [[String: Any]] = Bundle.main.array(plist: "Things.plist")

values[0]["id"] as? Int // 1
values[0]["name"] as? String // "Test 1"
values[0]["description"] as? String // "This is a test for 1.")

values[1]["id"] as? Int // 2)
values[1]["name"] as? String // "Test 2")
values[1]["description"] as? String // "This is a test for 2.")

values[2]["id"] as? Int // 3)
values[2]["name"] as? String // "Test 3")
values[2]["description"] as? String // "This is a test for 3.")

[Image of BundleArray](./Documentation/Images/BundleArray2.png)

Get a dictionary from a property list file within any bundle:

let values: [String: Any] = Bundle.main.contents(plist: "Settings.plist")

values["MyString1"] as? String // "My string value 1." values["MyNumber1"] as? Int // 123 values["MyBool1"] as? Bool // false values["MyDate1"] as? Date // 2018-11-21 15:40:03 +0000

let locale: Locale = .posix // en_US_POSIX

Decodable

Get a value of the type you specify, decoded from a JSON string.

let jsonString = "{\"test1\":29,\"test2\":62,\"test3\":33,\"test4\":24,\"test5\":14,\"test6\":72}"
let jsonObject: [String: Int] = jsonString.decode()

// Result [ "test1": 29, "test2": 62, "test3": 33, "test4": 24, "test5": 14, "test6": 72 ]

> Get a type-erased `Decodable` value:
```swift
let json = """
{
    "boolean": true,
    "integer": 1,
    "double": 3.14159265358979323846,
    "string": "Abc123",
    "date": "2018-12-05T15:28:25+00:00",

let decoder = JSONDecoder()
let dictionary = try decoder.decode([String: AnyDecodable].self, from: json)

dictionary["boolean"].value // true
dictionary["integer"].value // 1
dictionary["string"].value // Abc123

Skip failed elements during decoding instead exiting collection completely; lossy array decoding.

init(from decoder: Decoder) throws {
    let container = try decoder.container(keyedBy: CodingKeys.self)

self.authors = try container.decode(FailableCodableArray<Author>.self, forKey: .author)

}

    CLLocationCoordinate2D(latitude: 35.7750, longitude: -78.6336),
    CLLocationCoordinate2D(latitude: 33.720817, longitude: 73.090032)
]

coordinates.closest(to: homeCoordinate) coordinates.farthest(from: homeCoordinate)

> Determine if location services is enabled and authorized for always or when in use:
```swift
CLLocationManager.isAuthorized // bool

URL

Append a query string parameter to a URL:

let url = URL(string: "https://example.com?abc=123&lmn=tuv&xyz=987")
url?.appendingQueryItem("def", value: "456") // "https://example.com?abc=123&lmn=tuv&xyz=987&def=456"
url?.appendingQueryItem("xyz", value: "999") // "https://example.com?abc=123&lmn=tuv&xyz=999"

Append a dictionary of query string parameters to a URL:

let url = URL(string: "https://example.com?abc=123&lmn=tuv&xyz=987")
url?.appendingQueryItems([
    "def": "456",
    "jkl": "777",
    "abc": "333",
    "lmn": nil
]) // "https://example.com?xyz=987&def=456&abc=333&jkl=777"

Remove a query string parameter to a URL:

let url = URL(string: "https://example.com?abc=123&lmn=tuv&xyz=987")
url?.removeQueryItem("xyz") // "https://example.com?abc=123&lmn=tuv"

Query a URL from a parameter name:

let url = URL(string: "https://example.com?abc=123&lmn=tuv&xyz=987")
url?.queryItem("aBc") // "123"
url?.queryItem("lmn") // "tuv"
url?.queryItem("yyy") // nil

URLSession

A thin wrapper around URLSession and URLRequest for simple network requests:

let request = URLRequest(
    url: URL(string: "https://httpbin.org/get")!,
    method: .get,
    parameters: [
        "abc": 123,
        "def": "test456",
        "xyz": true
    ],
    headers: [
        "Abc": "test123",
        "Def": "test456",
        "Xyz": "test789"
    ]
)

let networkManager = NetworkManager( service: NetworkFoundationService() )

networkManager.send(with: request) { result in switch result { case let .success(response): response.data response.headers response.statusCode case let .failure(error): error.statusCode } }

Or call multiple URL requests simultaneously:
```swift
let request1 = URLRequest(
    url: URL(string: "https://httpbin.org/get")!,
    method: .get
)

let request2 = URLRequest(
    url: URL(string: "https://httpbin.org/post")!,
    method: .post
)

let request3 = URLRequest(
    url: URL(string: "https://httpbin.org/delete")!,
    method: .delete
)

networkManager.send(requests: request1, request2, request3) { firstResult, anotherResult, otherResult in
    switch firstResult {
    case let .success(response):
        response.data
    case let .failure(error):
        error.statusCode
    }

    switch anotherResult {
    case let .success(response):
        response.data
    case let .failure(error):
        error.statusCode
    }

    switch otherResult {
    case let .success(response):
        response.data
    case let .failure(error):
        error.statusCode
    }
}

Use an adapter to intercept any URLRequest and modify for all network requests:

struct CustomURLRequestAdapter: URLRequestAdapter {

func adapt(_ request: URLRequest) -> URLRequest {
    var request = request
    request.setValue("1", forHTTPHeaderField: "X-Test-1")
    request.setValue("2", forHTTPHeaderField: "X-Test-2")
    return request
}

}

let request = URLRequest( url: URL(string: "https://httpbin.org/get")!, method: .get )

let networkManager = NetworkManager( service: NetworkFoundationService(), adapter: CustomURLRequestAdapter() )

networkManager.send(with: request) { result in guard case let .success(response) else { return }

request.value(forHTTPHeaderField: "X-Test-1") == nil // true
request.value(forHTTPHeaderField: "X-Test-2") == nil // true

response.request.value(forHTTPHeaderField: "X-Test-1") == "1" // true
response.request.value(forHTTPHeaderField: "X-Test-2") == "2" // true

}

temp.value { $0 += 1 }
}

XCTAssertEqual(temp.value, 1_000_000) // true

AppMigration

    // Perform finite-length task...
    task.end()
}

Keychain

A thin wrapper to manage Keychain, or other services that conform to KeychainService:

let keychain = KeychainManager(
    service: KeychainExternalService()
)

keychain.set("kjn989hi", forKey: .token)

keychain.get(.token) { print($0) // "kjn989hi" }

    services: [
        LogServiceConsole(minLevel: .debug),
        LogServiceOS(
            minLevel: .warning,
            subsystem: "io.zamzam.Basem-Emara",
            category: "Application"
        ),

ZamzamNotification

UserNotification

Registers the local and remote notifications with the categories and actions it supports:

UNUserNotificationCenter.current().register(
    delegate: self,
    categories: [
        "order": [
            UNNotificationAction(
                identifier: "confirmAction",
                title: "Confirm",
                options: [.foreground]
            )
        ],
        "chat": [
            UNTextInputNotificationAction(
                identifier: "replyAction",
                title: "Reply",
                options: [],
                textInputButtonTitle: "Send",
                textInputPlaceholder: "Type your message"
            )
        ],
        "offer": nil
    ],
    authorizations: [.alert, .badge, .sound],
    completion: { granted in
        granted
            ? log.debug("Authorization for notification succeeded.")
            : log.warn("Authorization for notification not given.")
    }
)

Get a list of all pending or delivered user notifications:

UNUserNotificationCenter.current().getNotificationRequests { notifications in
    notifications.forEach {
        print($0.identifier)
    }
}

Find the pending or delivered notification request by identifier:

UNUserNotificationCenter.current().get(withIdentifier: "abc123") {
    print($0?.identifier)
}

UNUserNotificationCenter.current().get(withIdentifiers: ["abc123", "xyz789"]) { $0.forEach { print($0.identifier) } }

> Determine if the pending or delivered notification request exists:
```swift
UNUserNotificationCenter.current().exists(withIdentifier: "abc123") {
    print("Does notification exist: \($0)")
}

Schedules local notifications for delivery:

UNUserNotificationCenter.current().add(
    body: "This is the body for time interval",
    timeInterval: 5
)

UNUserNotificationCenter.current().add( body: "This is the body for time interval", title: "This is the snooze title", timeInterval: 60, identifier: "abc123-main" )

UNUserNotificationCenter.current().add( body: "This is the body for time interval", title: "This is the misc1 title", timeInterval: 60, identifier: "abc123-misc1", category: "misc1Category" )

UNUserNotificationCenter.current().add( body: "This is the body for time interval", title: "This is the misc2 title", timeInterval: 60, identifier: "abc123-misc2", category: "misc2Category", userInfo: [ "id": post.id, "link": post.link, "mediaURL": mediaURL ], completion: { error in guard error == nil else { return } // Added successfully } )

UNUserNotificationCenter.current().add( date: Date(timeIntervalSinceNow: 5), body: "This is the body for date", repeats: .minute, identifier: "abc123-repeat" )

> Get a remote image from the web and convert to a user notification attachment:
```swift
UNNotificationAttachment.download(from: urlString) {
    guard case let .success(attachment) = $0 else {
        log.error("Could not download the remote resource (\(urlString)): \($0.error?.debugDescription).")
        return
    }

    UNUserNotificationCenter.current().add(
        body: "This is the body",
        attachments: [attachment]
    )
}

Remove pending or delivered notification requests by identifiers, categories, or all:

UNUserNotificationCenter.current().remove(withIdentifier: "abc123")
UNUserNotificationCenter.current().remove(withIdentifiers: ["abc123", "xyz789"])
UNUserNotificationCenter.current().remove(withCategory: "chat") { /* Done */ }
UNUserNotificationCenter.current().remove(withCategories: ["order", "chat"]) { /* Done */ }
UNUserNotificationCenter.current().removeAll()
