SIGABRT (Signal abort) indicates that the app crash due to failure to access something which is nil or doesn?t exist, usually in my experience it?s Outlets.
- In the storyboard, check all your Outlets in each view controller.
2. Make sure you remove the connections with yellow warnings. These are invalid outlets.
3. Check your storyboard ID in the Identity Inspector if the names are correct.
4. Check for any breakpoint in the left side of the code.
Hope this helps someone!
