Convert NSData to NSString or vice versa in ObjectiveC and Swift.
Here is a Swift snippet that iterates through the bytes of an NSData and returns a string with hex. It also illustrates how to use ‘enumerateByteRangesUsingBlock’ to step through each byte in NSData.
func asHex(data: NSData) -> String { var resultAsHex: String = "" data.enumerateByteRangesUsingBlock({ (bytes, range, stop) -> Void in var chars = UnsafePointer<UInt8>(bytes) for i in 0...range.length-1 { resultAsHex += String(format: "%02x", UInt8(chars[i])) } }) return resultAsHex }

Converting NSString like so will force a trailing byte, which means NSJSONSerialization:JSONObjectWithData and others will fail unless you remove it.
I.e. do
NSData* data = [yourString dataUsingEncoding:NSUTF8StringEncoding];
and then
data = [data…
