Generic Initializer

init(_:)

Creates a new set from a finite sequence of items.

Declaration

convenience init<S>(_ sequence: S) where S : Sequence, DispatchSource.MachSendEvent.Element == S.Element

Parameters

sequence

The elements to use as members of the new set.

Discussion

Use this initializer to create a new set from an existing sequence, like an array or a range:

let validIndices = Set(0..<7).subtracting([2, 4, 5])
print(validIndices)
// Prints "[6, 0, 1, 3]"

Relationships

Generic Constraints

  • S : Sequence
    
  • Self.Element == S.Element
