Some statistics data I recently worked with included model identifiers for Apple devices. These identifiers are strings like
MacBookPro10,2 and indicate what device variant and generation the software was used on.
The raw identifier is not something you usually display in a user interface directly, instead you show a more friendlier name. Unfortunately a way to translate
iPad 2 (Wifi) is not readily available.
For that reason I created my own collection of iOS and Mac device model identifiers.
