A number of popular apps and services including TikTok, Spotify, Pinterest, and Tinder are currently broken on iOS devices, with early reports suggesting Facebook is to blame.
There are widespread reports on social media of apps crashing whenever they’re launched on iPhones and iPads, and corresponding outage spikes on DownDetector.com. The apps can be launched if the device is offline, which is useful in some cases (if you have lots of music saved on Spotify, for example) but will completely break their functionality in others.
Although the exact cause of the outages isn’t yet confirmed, early reports suggest the problem is caused by Facebook’s SDK, which many apps use to manage user logins. Users don’t have to be using Facebook to log into an app for this to affect their software. There are no similar reports of the same apps crashing on Android devices or on the web.
There’s another facebook SDK issue that lead’s to our iOS app to crash on launch again along with major apps like Spotify & Pinterest @fb_engineering

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.” In a thread on GitHub posted around 7AM ET, numerous developers reported problems with their apps.
A similar problem involving the Facebook SDK occurred in May and affected dozens of apps. The problems were mostly fixed that same day.
