Answer 1

You can use NSURL to safely isolate the filename then use substring to get the part you want.

let s = "https://storage.googleapis.com/user_avatars/63/img_-qLgH80SBqNhMRYbDQeccg.jpg"

Swift 2

if let url = NSURL(string: s),
    withoutExt = url.URLByDeletingPathExtension,
    name = withoutExt.lastPathComponent {
    let result = name.substringFromIndex(name.startIndex.advancedBy(5))
    print(result)
}

Swift 3

if let url = URL(string: s),
    withoutExt = try? url.deletingPathExtension(),
    name = withoutExt.lastPathComponent {
    let result = name.substring(from: name.index(name.startIndex, offsetBy: 5))
    print(result)
}

Swift 4

if let url = URL(string: s) {
    let withoutExt = url.deletingPathExtension()
    let name = withoutExt.lastPathComponent
    let result = name.substring(from: name.index(name.startIndex, offsetBy: 5))
    print(result)
}

Prints:

qLgH80SBqNhMRYbDQeccg
