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:
```swift
[1, 1, 3, 3, 5, 5, 7, 9, 9].distinct // [1, 3, 5, 7, 9]
```
> Remove an element from an array by the value:
```swift
var array = ["a", "b", "c", "d", "e"]
array.remove("c")
array // ["a", "b", "d", "e"]
```
> Easily get the array version of an array slice:
```swift
["a", "b", "c", "d", "e"].prefix(3).array
```
> Safely retrieve an element at the given index if it exists:
```swift
// Before
if let items = tabBarController.tabBar.items, items.count > 4 {
items[3].selectedImage = UIImage("my-image")
}
```
```swift
// 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:
```swift
// 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
}
```
Number
> 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:
```swift
String(random: 10) // "zXWG4hSgL9"
String(random: 4, prefix: "PIN-") // "PIN-uSjm"
```
> Safely use subscript indexes and ranges on strings:
```swift
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:
```swift
"[email protected]".isEmail // true
"123456789".isNumber // true
"zamzam".isAlpha // true
"zamzam123".isAlphaNumeric // true
```
> Remove spaces or new lines from both ends:
```swift
" Abcdef123456 \n\r ".trimmed // "Abcdef123456"
```
> Truncate to a given number of characters:
```swift
"Abcdef123456".truncated(3) // "Abc..."
"Abcdef123456".truncated(6, trailing: "***") // "Abcdef***"
```
> Determine if a given value is contained:
```swift
"1234567890".contains("567") // true
"abc123xyz".contains("ghi") // false
```
> Injects a separator every nth characters:
```swift
"1234567890".separated(every: 2, with: "-") // "12-34-56-78-90"
```
> Remove the characters contained in a given set:
```swift
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>4@5#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:
```swift
"1234567890".match(regex: "^[0-9]+?$") // true
"abc123xyz".match(regex: "^[A-Za-z]+$") // false
```
> Replace occurrences of a regular expression pattern:
```swift
"aa1bb22cc3d888d4ee5".replacing(regex: "\\d", with: "*") // "aa*bb**cc*d***d*ee*"
```
> Remove HTML for plain text:
```swift
"
This is web content with a link.
".htmlStripped // "This is web content with a link."
```
> Encoders and decoders:
```swift
value.urlEncoded()
value.urlDecoded()
value.htmlDecoded()
value.base64Encoded()
value.base64Decoded()
value.base64URLEncoded()
```
> Get an encrypted version of the string in hex format:
```swift
"[email protected]".sha256() // 973dfe463ec85785f5f95af5ba3906eedb2d931c24e69824a89ea65dba4e813b
```
> Easily get the string version of substring:
```swift
"hello world".prefix(5).string
```
> Determine if an optional string is `nil` or has no characters
```swift
var value: String? = "test 123"
value.isNilOrEmpty
```
### Foundation+
Bundle
> Get the string from a file within any bundle:
```swift
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:
```swift
let values: [String] = Bundle.main.array(plist: "Array.plist")
values[0] // "Abc"
values[1] // "Def"
values[2] // "Ghi"
```
```swift
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.")
```
> Get a dictionary from a property list file within any bundle:
```swift
let values: [String: Any] = Bundle.main.contents(plist: "Settings.plist")
values["MyString1"] as? String // "My string value 1."

```
> Remove a query string parameter to a URL:
```swift
let url = URL(string: "https://example.com?abc=123&lmn=tuv&xyz=987")
url?.removeQueryItem("xyz") // "https://example.com?abc=123&lmn=tuv"

url?.queryItem("yyy") // nil
```
URLSession
> A thin wrapper around `URLSession` and `URLRequest` for simple network requests:
```swift
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:
```swift
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
}
```
### Utilities

```swift
var temp = Atomic(0)
DispatchQueue.concurrentPerform(iterations: 1_000_000) { index in
temp.value { $0 += 1 }
}
XCTAssertEqual(temp.value, 1_000_000) // true
```
AppMigration
> Manages blocks of code that only need to run once on version updates in apps:
```swift
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
let migration = AppMigration()
func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil) -> Bool {
migration
.performUpdate {
print("Migrate update occurred.")
}
.perform(forVersion: "1.0") {
print("Migrate to 1.0 occurred.")
}
.perform(forVersion: "1.7") {
print("Migrate to 1.7 occurred.")
}
.perform(forVersion: "2.4") {
print("Migrate to 2.4 occurred.")
}
return true
}
}
```
BackgroundTask
> Easily execute a [long-running background task](https://developer.apple.com/documentation/uikit/uiapplication/1623031-beginbackgroundtask):
```swift
BackgroundTask.run(for: application) { task in
// Perform finite-length task...
task.end()
}
```
Keychain
> A thin wrapper to manage Keychain, or other services that conform to `KeychainService`:
```swift
let keychain = KeychainManager(
service: KeychainExternalService()
)
keychain.set("kjn989hi", forKey: .token)
keychain.get(.token) {
print($0) // "kjn989hi"
}
// Define strongly-typed keys
extension KeychainAPI.Key {
static let token = KeychainAPI.Key("token")
}
```
Logger
> Create loggers that conform to `LogService` and add to `LogManager` (console and `os_log` are included):
```swift
let log = LogManager(
services: [
LogServiceConsole(minLevel: .debug),
LogServiceOS(
minLevel: .warning,
subsystem: "io.zamzam.Basem-Emara",
category: "Application"
),
MyCustomLogger()
]
)
log.error("There was an error.")
```
SystemConfiguration
> Determine if the device is connected to a network:
```swift
import SystemConfiguration
SCNetworkReachability.isOnline
```
### Infixes
ConditionalAssignment ?=
> Assign a value if not nil:
```swift
var test: Int? = 123
var value: Int? = nil
test ?= value
// test == 123
value = 456
test ?= value
// test == 456
```
NilOrEmptyAssignment ??+
> Assign a value if not nil or empty:
```swift
var test: String
var value: String?
test = value ??+ "Abc"
// test == "Abc"
value = ""
test = value ??+ "Lmn"
// test == "Lmn"
value = "Xyz"
test = value ??+ "Rst"
// test == "Xyz"
```
## ZamzamLocation
LocationManager
> Location manager that offers `Combine` wrappers:

## ZamzamNotification
UserNotification
> Registers the local and remote notifications with the categories and actions it supports:
```swift
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:
```swift
UNUserNotificationCenter.current().getNotificationRequests { notifications in
notifications.forEach {
print($0.identifier)
}
}
```
> Find the pending or delivered notification request by identifier:
```swift
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:
```swift
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:
```swift
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()
```
