1. 1 Swift Poznań #1 Swift on Linux Błażej Wdowikowski
2. 2 SWIFT ON LINUX What we will talk about
3. 3 SWIFT ON LINUX What we will talk about Swift Package Manager and the environment What the program do Differences in Swift on Linux and macOS What Apple say about Swift port on Linux Is it worth to follow?
4. 4 SWIFT ON LINUX Swift Package Manager and the environment What the program do
5. 5 SWIFT ON LINUX Swift Package Manager and the environment import PackageDescription let package = Package( name: "Solam", targets: [ Target( name: "Solam", dependencies: ["ifaddrs"]), Target( name: "ifaddrs", dependencies: []), ], dependencies: []) #if os(macOS) package.dependencies = [ .Package(url: "https: //github.com/Anviking/Decodable.git", Version(0,5,1)), .Package(url: "https: //github.com/JohnSundell/Files", Version(1,9,0)) ] #elseif os (Linux) package.dependencies = [ .Package(url: "https: //github.com/JohnSundell/Files", Version(1,9,0)) ] #endif What the program do
6. 6 SWIFT ON LINUX Swift Package Manager and the environment import PackageDescription let package = Package( name: "Solam", targets: [ Target( name: "Solam", dependencies: ["ifaddrs"]), Target( name: "ifaddrs", dependencies: []), ], dependencies: []) #if os(macOS) package.dependencies = [ .Package(url: "https: //github.com/Anviking/Decodable.git", Version(0,5,1)), .Package(url: "https: //github.com/JohnSundell/Files", Version(1,9,0)) ] #elseif os (Linux) package.dependencies = [ .Package(url: "https: //github.com/JohnSundell/Files", Version(1,9,0)) ] #endif What program do
7. 7 SWIFT ON LINUX Swift Package Manager and the environment MacOS with Swift 3.1 Ubuntu 16.10, Swift 3.1.1 github.com/icanswiftabit/solam What the program do
8. 8 SWIFT ON LINUX What the program do Get an internal IP address using C
9. 9 SWIFT ON LINUX What the program do Read user input Get an internal IP address using C Make a sequenced HTTP request with GCD and URLSession Print proper messages into the console Deserialize JSON responses into structs Save output to a file with John Sundell's Files Get an internal IP address using C
10. 10 SWIFT ON LINUX What the program do Get an internal IP address using C Read user input Get an internal IP address using C Make a sequenced HTTP request with GCD and URLSession Print proper messages into the console Deserialize JSON responses into structs Save output to a file with John Sundell's Files
11. 11 SWIFT ON LINUX Get an internal IP address using C GCD and URLSession
12. 12 SWIFT ON LINUX Get an internal IP address using C Constants AF_INET, AF_INET6 are UInt16 on Linux and UInt8 on macOS struct sockaddr on Linux doesn't have sa_len field GCD and URLSession
13. 13 SWIFT ON LINUX GCD and URLSession JSON
14. 14 SWIFT ON LINUX GCD and URLSession JSON import Dispatch shared is not yet implemented
15. 15 SWIFT ON LINUX JSON What Apple say about Swift port on Linux
16. 16 SWIFT ON LINUX JSON What Apple say about Swift port on Linux On macOS, I use Decodable and it is pretty straightforward kingdom for a JSON deserialize on Linux
17. 17 SWIFT ON LINUX What Apple say about Swift port on Linux Swift is already ported to Linux
18. 18 SWIFT ON LINUX Swift is already ported to Linux What Apple say about Swift port on Linux In the most part
19. 19 SWIFT ON LINUX Swift is already ported to Linux Is it worth to follow? the GCD port was completed around May 20th random number generation some C structs are absent or only partially available some String APIs are missing due to NSString bridging on macOS some mechanisms that rely on Objective-C are missing
20. 20 SWIFT ON LINUX Is it worth to follow?
21. 21 SWIFT ON LINUX Is it worth to follow? server-side projects, such as Perfect, Kitura and Vapor IoT, because you can use Swift on embedded systems scripting, of course Questions?
22. 22 Questions?
