Our application provides car insurance services. Does Apple have any API related to car accident detection exposed to developers? We want to do something when an iPhone detects a car accident
There's no supported way for you to detect crashes at an API level with the APIs currently available. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here. If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?
