A number of popular iOS apps, including TikTok, Pinterest and Spotify, started crashing on Wednesday after updating Facebook’s SDK, software that many developers rely on to streamline the user login process.
According to online accounts, the applications integrating the Facebook SDK suffered from an error that caused them to crash immediately upon opening. An e on GitHub traced the problem to a server-side update, although Facebook has not confirmed an error on its end.
Around 6:30 p.m. The affected oriental applications like TikTok, Pinterest, Spotify, Tinder, Viber and others have been rendered non-functional. The problem appears to have affected all or almost all applications that integrate Facebook’s third-party login tools.
As noted by The Verge, the issues weren’t limited to application instances that actively used the Facebook login feature, as the apps also blocked for users who typically connect by other means.
The issue was resolved quickly, but the apparent Facebook fix took a long time to spread. Most applications were operational at 8:30 p.m., although some remained out of service at the time of writing.
Today’s problems highlight the dangers of using a third-party tool for essential services. While integration can help with integration and ease sticking points, it also puts app makers at the mercy of an outside entity, in this case, Facebook.
Apple also offers a user authentication service in “Connect with Apple”, although the functionality has not yet been widely adopted.
Presented as a login tool created with data security in mind, the single sign-on feature allows users to create a new account without exposing potentially sensitive private informationon and allows authentication via Face ID or Touch ID. The system also filters the informationon transmitted to the supplier via a specialized electronic mail transfer subsystem which allows users to hide their personal address with an anonymized version generated by application or service.
