A number of popular apps and services including TikTok, Spotify, Pinterest, and Tinder are currently broken on iOS devices.
There are widespread reports on social media of different apps crashing whenever they’re launched on iPhones and iPads, and there are also outage spikes for the same apps on DownDetector.com.
Although the exact cause of the problem isn’t yet confirmed, early reports suggest the outages are caused by Facebook’s SDK, which apps use to manage user logins. Facebook said on its developer platform this morning that it was “aware [of] and investigating an increase in errors on the iOS SDK which is causing some apps to crash.”
A similar problem involving the Facebook SDK occurred in May and affected dozens of apps.
