convert javascript regex expression to swift nsregularexpression

问题

I am new to swift programming.

I have a valid regex in javascript, I need the same functionality in swift

str.replace(/\+/g, '-').replace(/\//g, '_').replace(/\=+$/, '');

Thanks

Swift 2.3:

let str = "A+B/C===="

let result = str.stringByReplacingOccurrencesOfString("+", withString: "-")
                .stringByReplacingOccurrencesOfString("/", withString: "_")
                .stringByReplacingOccurrencesOfString("\\=+$", withString: "", options: .RegularExpressionSearch)

print(str)
print(result)

Swift 3:

let str = "A+B/C===="

let result = str.replacingOccurrences(of: "+", with: "-")
                .replacingOccurrences(of: "/", with: "_")
                .replacingOccurrences(of: "\\=+$", with: "", options: .regularExpressionSearch)

print(str)
print(result)
