For the second time this year, a bug in the Facebook SDK is causing third-party apps like Spotify, Pinterest, and TikTok to crash on launch. The affected third-party apps use the Facebook SDK to provide services such as account logins, ad platform integration, analytics, and more.
Any bugs in the underlying Facebook SDK will affect any apps that use it. This means improper handling of unexpected invalid data on Facebook’s part will result in the apps’ crashing.
Numerous apps use the Facebook SDK, which means a large number of iOS users will have issues launching many of their favorite apps.
Facebook says it is looking into the problem, and will likely have the server-side issue fixed shortly. This means users will simply need to cool their heels until the issue is fixed. On the bright side, users will not need to reinstall the affected apps.
Some users have found that apps can be launched in Airplane Mode successfully, but as most apps require network access to function, that’s of little comfort. But if your app can operate offline, this could be useful.
If Spotify is crashing on your iPhone you can avoid the crash bug by launching it with your phone in airplane mode and Wi-Fi turned off. As soon as you re-enable Wi-Fi or 4G then it'll crash again due to the Facebook iOS SDK issue
