random-swift

A utility for randomly generating data, content, and assets for iOS & macOS apps written in Swift.

CI Status Version License Platform Readme Score codebeat badge

[BETA]: this framework is not a complete set of features and is in active development. check the examples documented in this readme for confirmation of what is available.

Requirements

  • iOS v11.0 or higher
  • macOS v10.15 or higher (mac catalyst)

Installation

Cococapods

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

pod 'random-swift'

Swift Package Manager

add this repository to your project via Swift PM:

Documentation

Full public documentation of the framework can be found here.

Import Options

Import into entire project

Open AppDelegate.swift

Add an exported import statement to the top of the class like so:

@_exported import random_swift

The framework is now accessible in every class in your project.

Note: There are some differing opinions about @_exported import, namely, the risk of object and class name collisions between frameworks, however, if you don’t have any issues with the exported import approach in your project, you’re gonna be alright, and the convenience trade-off is probably worth it.

Import into class or file

After installing, import into your class:

import random_swift

Usage

Currently supported:

Global Accessibility & Persistent Configuration

  • Security & true randomness assured by leveraging the underlying arc4random() generator built into swift

  • Random is available as a shared instance within the imported scope (class, project, etc.)

     // access it with:
     Random.$type
    
  • A configuration set persists on the shared instance for the duration of the application session

     // setup an IntRange configuration
     let intRange = IntRange(lower: 4, upper: 100)
    
     // setup a percentage range configuration
     let pctRange = PercentageRange(min: 0.10, max: 0.98)
    
     // assign the configurations
     Random.intRange = intRange
     Random.percentageRange = pctRange
    

    While this shared instance is still in memory (i.e. the app is still running / not terminated or backgrounded), the last used configuration will be used as the default configuration for any calls for random values that need a range or an upper-bound limit.

  • You can dynamically use new range configurations if you need to change them on the fly for new requests

    An example retrieving a new randomValue with a new range config:

     // setup:
     let newIntRange = IntRange(lower: 1, upper: 5000)
     
     // get a random int value within the range
     let rangedInt = Random.int.withinRange(range: newIntRange)
     
     // get a random int value anywhere between 0 and the newIntRange.upper
     Random.int.withUpperLimit(of: newIntRange)
    

Notes:

  • All IntRange and numerical return types are exclusive of the upper-bound:
    • For example, if the upper-bound target value is 200 and the lower-bound value is 0, the only possible values that can return are 0 through 199.
      • If the upper-bound must include 200 as a possible return value, you simply need to setup the upper-bound as (upper-bound-target-value) + 1

Random Words

Random supports true random word generation.

Random words are generated from a static dictionary containing 235,886 words, all of which are packaged by default with macOS.

Functions

  • Get a random Word:

    let randomWord = Random.word
    


Random Values

Random.int

Functions

  • Get a random Int:

     let randomInt = Random.int.value()
    
  • Get a random Int value within a given range between upper and lower bounds, :

     // setup a range
     let newIntRange = IntRange(lower: 10, upper: 250)
     
     // get a random int value between range.lower and range.upper
     let randomIntWithinRange: Int = Random.int.withinRange(range: newIntRange)
    

Computed Properties

  • Get a random Int:

     let randomInt = Random.int.value
    

Note: The following computed properties require configuration to be in place beforehand.

These will always return 0 if:

- A config has not been set by using a function call
- or by directly configuring `Random.intRange`.

Usage is basically the same as a function call:

  • Get a random Int below a given IntRange upper-bound limit:

     // setup a range & configure
     let range = IntRange(lower: 10, upper: 200)
     Random.intRange = range
     
     // get a random int value within the range
     let rangedInt = Random.int.withinUpperLimit
    
  • Get a random Int value within a given range between lower and upper bounds:

     // setup a range & configure
     let range = IntRange(lower: 10, upper: 250)
     Random.intRange = range
     
     // get a random int value between range.lower and range.upper
     let randomWithinRange: Int = Random.int.withinRange
     // randomWithinRange == some Int between 10 and 200, exclusive of 200 (so max 199)
    

Random.percentage

Functions

  • Get a random percentage (as Double), rounded (optional) to a maximum decimal place value:

     let randomPct = Random.percentage.value(roundedTo: 5)
     // returns percentage with no more than 5 place values
     // e.g. 0.45369
    
  • Get a random percentage below a given PercentageRange max limit, rounded (optional) to a max number of decimal place values:

     // setup a range
     let range = PercentageRange(lower: 0.10, upper: 0.999)
    
     // get a random int value within the range
     let rangedPct: Double = Random.percentage.withUpperLimit(of: range, maxDecimalPlaces: 3)
     // returns percentage with no more than 3 decimal places
     // e.g. 0.294
    
  • Get a random percentage value within a given range, between min and max limits:

     // setup a range
     let range = PercentageRange(lower: 0.15, upper: 0.322)
     
     // get a random int value between range.lower and range.upper
     let randomPctWithinRange: Double = Random.percentage.withinRange(range, maxDecimalPlaces: 1)
     // returns percentage with no more than 1 decimal place
     // e.g. 0.6
    

Computed Properties

  • Get a random percentage (as Double):

     let randomPct: Double = Random.percentage.value
    

Note: the following computed properties require configuration to be in place beforehand.

These will always return 0.0 if:

- A config has not been set by using a function call

- or by directly configuring `Random.percentageRange`.

Usage is basically the same as a function call:

  • Get a random percentage below a given PercentageRange max limit:

     // setup a range & configure shared instance
     let range = PercentageRange(lower: 0.15, upper: 0.322)
     Random.intRange = range
     
     // get a random percentage value within the range
     let rangedPct: Double = Random.percentage.withUpperLimit
    
  • Get a random percentage value within a given range, between min and max limits:

     // setup a range & configure
     let range = PercentageRange(lower: 0.01, upper: 0.9)
     Random.intRange = range
     
     // get a random int value between range.lower and range.upper
     let randomPctWithinRange: Double = Random.percentage.withinRange
     // randomWithinRange == some Int between 0.01 and 0.9, exclusive of 0.9 (so max 0.89)
