notes from a developer, tutorials, how-to, ideas
Today I want to share a simple way to retrieve user data from a native iOS cache image, automatically generated when your app goes in background.
You can retrieve this kind of informations if your phone was lost or Jailbreaked or connecting it to your pc and open an old backup. You can use tools like iBackup Viewer and more…
Let’s see how it works!

The example of today is about machine learning to identify the mood of a collection of tweets (#apple, @apple, #covid-19, #love, etc…).
Classes, structures, and enumerations can define subscripts, which are shortcuts for accessing the member elements of a collection, list, or sequence. You use subscripts to set and retrieve values by index without needing separate methods for setting and retrieval. For example, you access elements in an
Arrayinstance assomeArray[index]and elements in aDictionaryinstance assomeDictionary[key].You can define multiple subscripts for a single type, and the appropriate subscript overload to use is selected based on the type of index value you pass to the subscript. Subscripts are not limited to a single dimension, and you can define subscripts with multiple input parameters to suit your custom type’s needs.
