Like Configuration, but don't think JSON or Plist-flavored XML are good markup languages for writing human-friendly configuration files? I agree. Let's use INI files instead.
Unlike JSON, INI files support comments, and have a far lower "noise" level than both XML and JSON.
Let's write an INI file that looks like this.
; Configuration file for my great Swift app
; Lines that start with the ; character are comments
; Site name
site-name = My Great Site
; Site root URL
site-url = https://example.com/mygreatsite
; Database credentials and configuration
[database]
username = hello
password = worldNow in your Swift project, add Configuration-INIDeserializer using SPM. Once done, here's how you can use it in your code.
import Configuration
import Configuration_INIDeserializer // <= Note the underscore
let config = Configuration()
// Tell Configuration how to read INI files. Don't forget this line!
config.use(INIDeserializer())
// Now you can load an INI file
config.load(file: "/path/to/my-config.conf")
// For top-level values, cast from the top level of the configuration "array"
let siteName = config["site-name"] as? String ?? "Default Site Name"
// For values in sections, try casting the section as a [String: String]
guard let databaseCredentials = config["database"] as? [String: String] else {
print("Can't find database credentials")
exit(1)
}
let databaseUsername = databaseCredentials["username"]Yet Another Swift Project by Nocturnal
