Open Radar

 
Summary:
If a URL contains a path and parameters the separator between path and parameters (;) is escaped to %3B and thus the separation fails

Steps to Reproduce:
1. open the attached storyboard.
2. Not that the assert at the end fails because the initial and reassembled URLs are not equal


Expected Results:
initial and reassembled URLs are equal

Actual Results:
initial and reassembled URLs are not equal


Version:
Xcode 7.2

// example URL string from the NSURL class documentation.
let urlString = "https://johnny:p4ssw0rd@www.example.com:443/script.ext;param=value?query=value#ref"

// convert to an NSURL object
guard let initialURL = NSURL(string: urlString) else {
    preconditionFailure()
}

// disassemble into NSURLComponents
guard let components = NSURLComponents(URL: initialURL, resolvingAgainstBaseURL: true) else {
    preconditionFailure()
}

// reassemble back into an NSURL object
let reassembledURL = components.URL

// whoops! The two are not equal. (the ; separating path and parameters was converted into %3B)
assert(initialURL == reassembledURL)
