Is your safari crashing on iPhone or Mac? Fix inside
Steven Troughton-Smith, an iOS developer, notes that the problems are related to Safari's search suggestions feature. Simply disabling this feature will stop Safari crashing, or using the private mode option in the browser as a temporary workaround. Not everyone is affected, and this could be because some have the search suggestions cached locally or they're still able to reach Apple's servers thanks to a DNS cache. The Verge has reached out to Apple for comment on the problems, and we'll update you accordingly.
