Valve SteamID wiki

// STEAM_X:Y:Z 
func convertToSteam32ID(steamString: String) -> UInt64 { 
    let array = steamString.componentsSeparatedByString(":") 
    let Y = UInt64(array[1])! 
    let Z = UInt64(array[2])! 
    return (Z << 1) | Y 
} 

func convertToSteam64ID(accountID accountID: UInt64) -> UInt64 { 
    let Universe: UInt64 = 1 
    let AccountType: UInt64 = 1 
    let Instance: UInt64 = 1 
    return ((Universe << 56) | (AccountType << 52) | (Instance << 32) | accountID) 
} 

let steam32ID = convertToSteam32ID("STEAM_0:1:21643603") 

let steam64ID = convertToSteam64ID(accountID: steam32ID)
