🗂 Swift Lanuage C/C++ Interoperability Description

🏷 CBool

• The C ‘_Bool’ and C++ ‘bool’ type.

typealias CBool = Bool

🏷 CChar

• The C ‘char’ type. This will be the same as either CSignedChar (in the common case) or CUnsignedChar, depending on the platform.

typealias CChar = Int8

🏷 CChar16

• The C++11 ‘char16_t’ type, which has UTF-16 encoding.

typealias CChar16 = UInt16

 

🏷 CChar32

• The C++11 ‘char32_t’ type, which has UTF-32 encoding.

typealias CChar32 = Unicode.Scalar

🏷 CDouble

• The C ‘double’ type.

typealias CDouble = Double

 

🏷 CFloat

• The C ‘float’ type.

typealias CFloat = Float

🏷 CInt

• The C ‘int’ type.

typealias CInt = Int32

 

🏷 CLong

• The C ‘long’ type.

typealias CLong = Int

 

🏷 CWideChar

• The C++ ‘wchar_t’ type.

typealias CWideChar = Unicode.Scalar

🏷 CLongLong

• The C ‘long long’ type.

typealias CLongLong = Int64
