swiftCache

Volatile and Persistent cache interfaces and implementation

Installation

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

pod 'SwiftfulCache'

Alternatively, you can build the project from this repository and then put the framework inside your own project.

Usage

After that, you can use it importing the framework and initializing a specialized Cache, for example:

 class SomeClass {
  // You can use only the RAM Cache
  let volatileCache: VolatileCacheable = Cache<String, YourObject>()
  // or Persistent which includes Volatile
  let persistentCache: PersistentCacheable = Cache<String, YourObject>()
  // or, just the Cache class, which has a few default values on the function signatures.
  // Using the Cache class will load both Volatile and Persistent Cache
  let cache: Cache<String, YourObject> = .init()
 }

For persistent cache, using the .cachesDirectory allows the system to clean the files as its own rules. A valid alternative is to use .documentsDirectory which will allow you to store the data, as long as your app exists, by your own terms.

What is done

• Volatile cache set, get, remove, get keys, and subscript functions
• Persistent cache persist to file and load from file to Volatile cache functions
• Volatile tests for set, get, remove, get keys functions
• Volatile performance tests for set, get, remove and get keys functions
• Persistent parcial tests for both persist and load functions
• Added basic error handling for persist and load functions
• PersistentCacheable full test coverage for persist and load functions
• PersistentCacheable performance tests
• Make CacheManager Framework accesible from Cocoapods

TODO

• Make CacheManager Framework accesible from Carthage
