Spotify (SPOT) - Get Report is one of numerous popular apps that are crashing on Apple's (AAPL) - Get Report iOS operating system, and reports point to Facebook (FB) - Get Report as the reason for the outages.
App outage tracker DownDetector.com tracked thousands of app crashes whenever they were launched on iPhones or iPads. Early reports say the problem is being caused by Facebook's Software Development Kit, or SDK, which many apps use to manage user logins.
"Facebook SDKs enable you to pass app-event data from your app to Facebook. With app event data, you can accurately track and measure the actions people take in your app.," Facebook's developer website says.
Requests for comment from Facebook and Spotify were not returned in time for publication.
Facebook's developer platform said that it is "aware and investigating an increase in errors on the iOS SDK which is causing some apps to crash."
According to the site, it began receiving those error messages on July 5 with its last update being "about an hour ago."
