Swift code generator. Generate strongly typed enums based on your Info.plist and Asset Catalog. No more magic strings!
Swifterate is distributed as a Ruby gem.
$ gem install swifterateAfter installing, the swifterate command is available:
$ swifterate help
Commands:
swifterate ac DIR # Generate Swift code from an Asset Catalog directory located at DIR
swifterate help [COMMAND] # Describe available commands or one specific command
swifterate plist FILE # Generate Swift code from the .plist file located at FILEThe generated Swift code is printed to the console. You can redirect the output to a file instead:
$ swifterate plist test/fixtures/Info.plist > InfoPlist.swiftSwifterate currently supports .plist and .xcassets as inputs to generate Swift code.
Generate a swift enum from the following MyApp-Info.plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>CFBundleName</key>
<string>MyApp</string>
<key>CFBundleShortVersionString</key>
<string>1.0.0</string>
<key>CFBundleVersion</key>
<string>100</string>
</dict>
</plist>The following is generated with the command: swifterate plist MyApp-Info.plist
enum InfoPlist: String {
case CFBundleName = "CFBundleName"
case CFBundleShortVersionString = "CFBundleShortVersionString"
case CFBundleVersion = "CFBundleVersion"
private var infoDictionary: [NSObject : AnyObject] {
return NSBundle.mainBundle().infoDictionary!
}
var dictionary: [NSObject : AnyObject] {
return infoDictionary[rawValue] as! [NSObject : AnyObject]
}
var array: [AnyObject] {
return infoDictionary[rawValue] as! [AnyObject]
}
var data: NSData {
return infoDictionary[rawValue] as! NSData
}
var date: NSDate {
return infoDictionary[rawValue] as! NSDate
}
var number: NSNumber {
return infoDictionary[rawValue] as! NSNumber
}
var string: String {
return infoDictionary[rawValue] as! String
}
init(_ key: InfoPlist) {
self = key
}
}To use the generated enum:
let appName = InfoPlist(.CFBundleName).string // "MyApp"Generate a UIImage extension with an enumerated list of assets from the Asset Catalog:
MyApp.xcassets/
AppIcon.appiconset/
LaunchImage.launchimage/
MyAppLogo.imageset/
PrimaryButton.imageset/The following is generated with the command: swifterate ac MyApp.xcassets
extension UIImage {
enum MyAppAsset: String {
case MyAppLogo = "MyAppLogo"
case PrimaryButton = "PrimaryButton"
}
convenience init!(assetIdentifier: MyAppAsset) {
self.init(named: assetIdentifier.rawValue)
}
}Notice that the AppIcon and LaunchImage aren't included. They cannot be referenced using UIImage(imageNamed:)
To use the generated extension:
let myAppLogo = UIImage(assetIdentifier: .MyAppLogo)Swifterate is available under the MIT license. See the LICENSE file for more info.
