Swift equivalent to Objective-C FourCharCode single quote literals (e.g. 'TEXT') -

i trying replicate objective c cocoa in swift. until come across following:

// set new type , creator: unsigned long type = 'text'; unsigned long creator = 'pdos'; 

how can create int64s (or correct swift equivalent) single quote character literals this?

i'm using in cocoa scripting apps, considers characters > 0x80 correctly

func ostypefrom(string : string) -> uint {   var result : uint = 0   if let data = string.datausingencoding(nsmacosromanstringencoding) {     let bytes = unsafepointer<uint8>(data.bytes)     in 0..<data.length {       result = result << 8 + uint(bytes[i])     }   }   return result } 

edit:

alternatively

func fourcharcodefrom(string : string) -> fourcharcode {   assert(string.characters.count == 4, "string length must 4")   var result : fourcharcode = 0   char in string.utf16 {     result = (result << 8) + fourcharcode(char)   }   return result }
