Today, December 21st, all 6 of my personal apps on my iPhone 6 and iPad crashed immediately upon opening. These are apps I wrote and put on my own devices (not through the Apple store), some of which have been running for years. Restarting the devices did not fix the problem. What did fix it was plugging my device into the computer and running the apps through XCode. After that, they worked again without being connected.
Has anyone else experienced this? Did Apple change something today that made this happen?
