utf8String
A null-terminated UTF8 representation of the string.
Declaration
var utf8String: UnsafePointer<CChar>? { get }Discussion
This C string is a pointer to a structure inside the string object, which may have a lifetime shorter than the string object and will certainly not have a longer lifetime. Therefore, you should copy the C string if it needs to be stored outside of the memory context in which you use this property.
