Replacing \\ with \ in Swift

Question

I have a requirement where I want to replace "\\\\" with "\\" however it does not seem to work.

var st = "satya\\"
st = st.replacingOccurrences(of: "\\", with: "\", options: 
NSString.CompareOptions.literal,
range: nil)

Answer 1

You should escape the backslashes if you want to replace two backslashes with one.

st.replacingOccurrences(of: "\\\\", with: "\\", options: .literal, range: nil)

However, as @VTodorov mentioned, "satya\\\\" is actually stored as satya\\ , since you already escaped a backlash in it. If you want to store a string with two backslashes, you should write it as "satya\\\\\\\\" .
