NikolajMosbaek / String+localization.swift

Last active November 23, 2022 08:23

An extension which adds syntactic sugar when using localized strings. You can write: 'let loginTitle = "login_title_key"'

	extension String {
	var localized: String {
	let local = NSLocalizedString(self, comment: "")
	guard !local.isEmpty else {
	return self
	}
	return local
	}
	}

NikolajMosbaek / SpaceOperator.swift

Created June 7, 2022 12:05

This is how you can create the spaceship operator found in many other programming languages

	infix operator <=>

	func <=><T: Comparable>(lhs: T, rhs: T) -> ComparisonResult {
	if lhs < rhs { return .orderedAscending}
	if lhs > rhs { return .orderedDescending }
	return .orderedSame
	}

NikolajMosbaek / fuzzyFilter.swift

Created June 1, 2022 15:13

With this code you can make an object Searchable and define which parameters that should be included in a search. Then you can easily call .fullyFilter(for: someString) on the object

	protocol Searchable {
	var keyPaths: [KeyPath<Self, String>] { get }
	}

	extension Searchable {
	func matches(_ searchString: String) -> Bool {
	for path in keyPaths {
	let value = self[keyPath: path]

	if value.localizedCaseInsensitiveContains(searchString) {

	let value = self[keyPath: path]

	let value = self[keyPath: path]

	if value.localizedCaseInsensitiveContains(searchString) {

NikolajMosbaek / runFunctionOnValues.swift

Created June 1, 2022 15:03

This code will func a function on every value on any object

	func mirror(_ value: Any, using function: (Any) -> Void) {
	let mirror = Mirror(reflecting: value)

	for child in mirror.children {
	function(child.value)
	}
	}

NikolajMosbaek / fuzzyMatch.swift

Created June 1, 2022 14:59

This code will try to match a (search) string to any of an object's string attributes

	func ~=(lhs: Any, rhs: String) -> Bool {
	let mirror = Mirror(reflecting: lhs)

	for child in mirror.children {
	guard let value = child.value as? String else { continue }
	if value.localizedCaseInsensitiveContains(rhs) {
	return true
	}
	}

NikolajMosbaek / PhoneOnlyNavigationView.swift

Created April 27, 2022 12:50

An extension to force stacked navigation style on phones

	extension View {
	@ViewBuilder func phoneOnlyNavigationView() -> some View {
	if UIDevice.current.userInterfaceIdiom == .phone {
	self.navigationViewStyle(.stack)
	} else {
	self
	}
	}
	}

NikolajMosbaek / Bundle-Decodable.swift

Created April 27, 2022 11:44

A universal way to decode a bundle

	extension Bundle {
	func decode<T: Decodable>(_ file: String) -> T {
	guard let url = self.url(forResource: file, withExtension: nil) else {
	fatalError("Failed to locate \(file) in bundle.")
	}

	guard let data = try? Data(contentsOf: url) else {
	fatalError("Failed to load \(file) from bundle.")
	}

NikolajMosbaek / withOptionalAnimation.swift

Last active April 27, 2022 11:46

Use this method to support reduced motion from accessibility

	@Environment(\.accessibilityReduceMotion) var reduceMotion

	func withOptionalAnimation<Result>(_ animation: Animation? = .default, _ body: () throws -> Result) rethrows -> Result {
	if UIAccessibility.isReduceMotionEnabled {
	return try body()
	} else {
	return try withAnimation(animation, body)
	}
	}
