Functions

The following functions are available globally.

  • Execute the task closure on specified queue after delayed seconds.

    Declaration

    Swift

    @discardableResult
public func delay(_ delayedSeconds: TimeInterval, queue: DispatchQueue = .global(), task: @escaping () -> Void) -> DelayTask

    Parameters

    delayedSeconds

    The delayed seconds.
    queue

    The dispatch queue to run on.
    task

    The closure to run.

  • Linearly interpolates between start and end by t. The parameter t is clamped to the range [0, 1]. When t = 0 returns start. When t = 1 return end. When t = 0.5 returns the midpoint of start and end.

    Declaration

    Swift

    public func lerp<T>(start: T, end: T, t: T) -> T where T : BinaryFloatingPoint

    Parameters

    start

    The start value.
    end

    The end value.
    t

    The interpolation value between the two floats.

    Return Value

    The interpolated float result between the two float values.

Optional Assignment Operator

  • Optional Assignment Operator

    If the rhs is .None then this operator behaves as a no operation. If the rhs is `.Some(T) then this operator safely unwraps and binds the value so that it can be assigned to lhs

    Declaration

    Swift

    public func =? <T>(lhs: inout T, rhs: T?)

    Parameters

    lhs

    a non-optional variable of a given type T
    rhs

    an optional value of type T?

  • Optional Assignment Operator

    If the rhs is .None then this operator behaves as a no operation. If the rhs is `.Some(T) then this operator safely unwraps and binds the value so that it can be assigned to lhs

    Declaration

    Swift

    public func =? <T>(lhs: inout T?, rhs: T?)

    Parameters

    lhs

    a non-optional variable of a given type T
    rhs

    an optional value of type T?

Optional String Coalescing Operator

  • Undocumented

    Declaration

    Swift

    public func ??? <T>(lhs: T?, defaultValue: @autoclosure () -> String) -> String
