使用Swift的String的ASCII编码

Question

What I need to do is Convert a String to byte array with ASCII encoding… I'm using Swift and I can see the utf-8, utf-16 and unicodeScalars but no Ascii encoding found for String.

How can I do it? For example for a string like “ID00000004” the content of the bytes should be “49443030303030303034”

Can you help me? Thanks in advance

Answer 1

the following code is correct, the result was printed in console in decimal instead of hex

var result : [Byte] = UInt8

Thank you
