iOS 13 beta erases files off drive, resets iPad: FAT12 issue it seems…? @apple
Update: As of 6/29/19 … same issue across all betas.
OK! The upcoming iOS 13 allows iPads to be more like computers, which means being able to do computer-like things such as plugging in a USB drive, opening up the Files app in iOS 13 and browsing the files. This is going to be fantastic for folks who want to use an iPad as their full-time desktop replacement, and if you’re a coder it looks like you’ll be able to do things like opening up Python .py files, use IDEs for coding, etc.
However! iOS beta 1 deletes files off some devices that are USB-Drive-like, for example, all the CircuitPython boards. The iPad also resets itself, so that’s not super-great either.
Here is the Circuit Playground Express as it appears on the latest version(s) of Mac OS. Shows up as a USB drive, all it well. Copy, deleted, move, it’s just like a USB drive that happens to be Python device.
Plugging in the Circuit Playground express to the iPad running iOS 13 beta 1, will at first correctly run, light up, based on the code stored on the drive code.py. However, it quickly, almost immediately changes the name of the drive from CIRCPY to XXXERROR on the iPad. The iPad then deletes all the files off the drive.
If you are fast you can see that the files are there before they are deleted, and a new file that has zero bytes is displayed, and it’s from the year 2031.
We made a video to show all this happening (video).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
