Stella 1.1.0

Stella contains a set of utilities that can be used during iOS development in Swift.

TOC

Installation

Stella is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'Stella', '~> 1.1'

Features

Defaults

We have a cleaner way to use NSUserDefaults. Define the user defaults by extending the DefaultsKeys class.

extension DefaultsKeys {
  // Writes a string object to the defaults with the 'stringValue' key.
  static let stringValue = DefaultsKey<String?>("stringValue")
  // Writes an integer to the defaults with the 'integerValue' key.
  static let integerValue = DefaultsKey<Int?>("integerValue")
  // Writes a double to the defaults with the 'doubleValue' key.
  static let doubleValue = DefaultsKey<Double?>("doubleValue")
  // Writes a float to the defaults with the 'floatValue' key.
  static let floatValue = DefaultsKey<Float?>("floatValue")
  // Writes a bool to the defaults with the 'booleanValue' key.
  static let booleanValue = DefaultsKey<Bool?>("booleanValue")
  // Writes a date object to the defaults with the 'dateValue' key.
  static let dateValue = DefaultsKey<NSDate?>("dateValue")
}

You can read/write the from/to the NSUserDefaults by using the subscript on the Defaults class.

Defaults[.stringValue] = "A string value"
print(Defaults[.stringValue]) // Prints 'A string value'

Defaults[.integerValue] = 123
print(Defaults[.integerValue]) // Prints '123'

Defaults[.doubleValue] = 123.123
print(Defaults[.doubleValue]) // Prints '123.123'

Defaults[.floatValue] = 123.321
print(Defaults[.floatValue]) // Prints '123.312'

Defaults[.booleanValue] = true
print(Defaults[.booleanValue]) // Prints 'true'

Defaults[.dateValue] = NSDate()
print(Defaults[.dateValue]) // Prints '1996-12-19T16:39:57-08:00'

Keychain

We have a cleaner way to use the Keychain. Define the user defaults by extending the Keys class.

extension Keys {
  // Writes a string object to the keychain with the 'stringValue' key.
  static let stringValue = Key<String?>("stringValue")
}

You can read/write the from/to the Keychain by using the subscript on the Keychain class.

Keychain[.stringValue] = "A string value"
print(Keychain[.stringValue]) // Prints 'A string value'

Localization

Localize a key in no time with this handy localization function.

let key = "this_is_your_localization_key"
print(key.localizedString)
// The debug console will print the localized
// string found in your .strings file.

Printing

Add something extra to your debug output. There are three extra functions available for you to use.

printAction("This is a user action.")
// The debug console will print `🎯 This is a user action.`

printBreadcrumb("This is your breadcrumb.")
// The debug console will print `🍞 This is your breadcrumb.`

printError("This is an error.")
// The debug console will print `🔥 This is an error.`

printQuestion("This is a question")
// The debug console will print `❓ This is an question.`

Print Levels

You can simply specify print levels like:

Output.level = .verbose

or to only print errors

Output.level = .error

Or just shut up everything, handy for in unit tests.

Output.level = .nothing

To see what is printed for what level look at the PrintSpec.

Bucket List

Here is an overview what is on our todo list.

  • [ ] The sharedInstance should be more configurable with a closure.
  • [ ] Add keychain integration.
