Helpers

Tiny convenient code pieces that I'm tired of copy-paste across all my projects.

Swift Stdlib Extensions and Common things I need sometimes (Helpers):

Array;

subscript (safe index: Int) -> Element?
func subtract(_ other: [Element]) -> [Element]
func distance(to index: Index) -> Int 

Decimal;

var doubleValue: Double

Double;

func roundToDecimals(_ decimals: Int, rule: FloatingPointRoundingRule = .toNearestOrAwayFromZero) -> Double

Date;

• work with unixMilliseconds;
• date components;
• beginning/end of date components;
• adding date components;
• comparison.

UserDefaults;

• provides getter and setter for Codable values.

Something I need sometimes;

• struct DateRange;
• protocol AppDetails - provides app version and build number;
• protocol AppStoreReview - provides dialog for Rate Us;
• protocol DeviceDetails - provides device model, system version and device locale;
• protocol ErrorLocalizedDescription;
• Formatter - easy way to format numbers;
• JsonObject - pretty typealias for [String: Any].

Combine (HelpersCombine)

• Publisher:

func mapToVoid()
func mapToOptional()
func flatMapLatest()
func filterFalse() 
func filterTrue() 
func invert() 
func mapArray<T>(transform)
func shareReplay(bufferSize)    // Adapted from https://www.onswiftwings.com/posts/share-replay-operator/ 

• Future:

convenience init(asyncFunc: @escaping () async throws -> Output)
convenience init(asyncFunc: @escaping () async -> Output)

In-App (HelpersIAP):

• IAPProduct model;

RxSwift Extensions (HelpersRxSwift):

func mapToVoid()
func filterFalse()
func filterTrue()
func invert()
func asDelayedActivity(_ delay: DispatchTimeInterval = .milliseconds(200))
func mapArray<T>(transform)
func fromAsync(_ block: { element in ... }) -> Single<Element>

SwiftUI (HelpersSwiftUI):

ViewExtension:

/// Applies the given transform if the given condition evaluates to `true`
@ViewBuilder func `if`<Content: View>(_ condition: @autoclosure () -> Bool, transform: (Self) -> Content) -> some View

Modifiers:

func blink(on state: Binding<Bool>, duration: Double = 0.1)
func navigationBarColors(background: Color, tint: Color)
func onFrameChange(enabled isEnabled: Bool = true, frameHandler: @escaping (CGRect)->Void)
func cornerRadius(_ radius: CGFloat, corners: UIRectCorner)
func onRotate(perform action: @escaping (UIDeviceOrientation) -> Void)
func rotateHandling(anchor: UnitPoint = .center)
func rotated(_ angle: Angle)
func shimmer(isActive: Bool = true, speed: Double = 0.15, angle: Angle = .init(degrees: 70), opacity: Double = 1.0)

Shapes:

func cornerRadius(_ radius: CGFloat, corners: UIRectCorner)
