## What is Adaptivity (A)?

Adaptivity is an invaluable tool for developers and designers. Use it to visualize how Size Classes and margins for layout, readable content and the safe area look on real devices and how they change with respect to orientation, iPad multitasking and Dynamic Type size changes. A comprehensive System Images browser shows the different SF Symbols data sets across iOS versions with availability, localization and name change information. There are also views for visualizing Dynamic Type styles, System Colors, System Fonts and System Materials.

*2022-12-22, version 9.3*

absolutely invaluable tool for developers of any Apple platform. reading docs, tutorials, HIG, etc is one thing. but actually being able to see, play with, and explore all the platform provided UI mechanisms on an actual device provides nearly limitless inspiration for my own apps. there’s just sooooo many nice things about this tool, trust me it’s worth it’s price of entry. this is one of a few dev tools i’m happy and eager to recommend to fellow devs and coworkers

*2022-05-31, version 8.8*

Adaptivity has been incredibly useful, especially for someone like me with the design talents of a dead fish and the income of a busker preventing me from paying a real designer to help me build apps. I have this app open just about every time I’m using Xcode.
