If you’ve been experiencing the bug where the iOS version of Snapchat crashes at launch, it seems that there’s now an update to fix it available in the App Store. The bug that’s been fixed by the update didn’t appear to have affected the Android version of the app.
Before updating to the latest version, 18.104.22.168, the app would give me a message that something went wrong, before crashing to Springboard on my iPhone 12 Mini. Now, I’m no longer getting the error, and have successfully been able to send a Snap.
The Snapchat Support Twitter account hasn’t yet tweeted about the fix (despite having a pinned tweet talking about the bug), but Snap’s SVP of Product has tweeted about the issue being fixed. Both myself and one of my co-workers tested the update, and it fixed the crashing issue for both of us.
If your phone isn’t automatically downloading the update, you can grab it yourself by going to the App Store, tapping on your profile picture in the top right corner, and pulling down to refresh. Any available updates should appear, and you can download them. If you turned off Auto-update to avoid the bugged version, you can turn it back on by going to Settings > App Store, and then toggling App Updates on under Automatic Downloads.
