Swift 4.2+

#### macOS

``` 

$ brew install pcre2

```

#### Ubuntu Linux

```

$ sudo apt-get install libpcre2-dev

```

### Swift Package Manager

Add dependencies to your Package.swift

``` swift

.package(url: "https://github.com/RockfordWei/Perfect-PCRE2.git", 

	from: "3.1.0")

// on target section:

.target(

            // name: "your project name",

            dependencies: ["PerfectPCRE2"]),

```

### Import Perfect PCRE2 Library

```

### Simple Usage

``` swift

let lines = try """

	HTTP/1.1 100 continue

	HTTP/1.0 200 OK

""".pcre2Match(pattern: "([A-Z]+)/([0-9.]+)\\s+([0-9]+)\\s+(.*)")

lines.forEach { line in

	print("full: $0", line[0]) // the full match

	print("head: $1", line[1]) // "HTTP"

	print("vers: $2", line[2]) // 1.1 or 1.0

	print("code: $3", line[3]) // 100 or 200

	print("stat: $4", line[4]) // continue or OK
