Required Initializerswift 6.0.1Swift
init(_:)
Creates a new instance from the given integer.
init<T>(_ source: T) where T : BinaryInteger Parameters
- source
An integer to convert.
sourcemust be representable in this type.
If the value passed as source is not representable in this type, a runtime error may occur.
let x = -500 as Int
let y = Int32(x)
// y == -500
// -500 is not representable as a 'UInt32' instance
let z = UInt32(x)
// ErrorOther requirements

Type members
associatedtype WordsA type that represents the words of a binary integer.
init<T>(T) Creates an integer from the given floating-point value, rounding toward zero.
init<T>(clamping: T) Creates a new instance with the representable value that’s closest to the given integer.
init?<T>(exactly: T) Creates an integer from the given floating-point value, if it can be represented exactly.
init<T>(truncatingIfNeeded: T) Creates a new instance from the bit pattern of the given instance by sign-extending or truncating to fit this type.
static var isSigned: BoolA Boolean value indicating whether this type is a signed integer type.
static func % (lhs: Self, rhs: Self) -> Self Returns the remainder of dividing the first value by the second.
static func %= (lhs: inout Self, rhs: Self) Divides the first value by the second and stores the remainder in the left-hand-side variable.

Citizens in Swift
Default implementations
init<T>(T) Creates a new instance from the given integer.
init<T>(T) Creates a new instance from the given integer.
init?(String) Creates a new integer value from the given string.
init<T>(T) Creates an integer from the given floating-point value, rounding toward zero. Any fractional part of the value passed as
sourceis removed.
Extension in BitCollections
Default implementations
init(BitArray) Creates a new instance from the bits in the given bit array, if the corresponding integer value can be represented exactly. If the value is not representable exactly, then a runtime error will occur.
