App crashes on launch on iOS 10

Question

I have my app building successfully in Xcode 8 for iOS 10, but as soon as the app launches in the simulator, it crashes without breaking in Xcode. Here is the log output:

Answer 3

This may not help, but I was having a similar log output with no app crash. I spoke to an Apple engineer at WWDC and he said it should be fixed for the next seed of Xcode 8 (they caught the issue too late for the initial beta version) so I won't see the logs when that's released. Maybe it'll be improved for you too.

Answer 6

I had a similar issue, found an answer on this forum

Turns out - the app will crash if you call EventKit, ContactsKit, Microphone, Camera etc etc that requires permissions without Info.plist keys like

Privacy - Location When In Use Usage Description

Privacy - Media Library Usage Description

...

Hey this is awesome, thanks a lot!

I added a "Privacy - Photo Library Usage Description" key to my info.plist, since my projects uses the Photos api, and the project now runs on ios10 !

Answer 10

You may right! But... I don't have the kit you list, I use coredata, parse, blts, UIKit, which are not what u said. I check the info.plist relate to "privacy - " it have 37 items, therefore, should I add all 37 items to be true into the info.plist file?

I've also tried to add all privacy statement in the info.plist, but still no luck. There is an openradar issue https://openradar.appspot.com/26843578 for similar issue. It could be an assertion in CFNetwork for our case. See the openradar post for more detail.

I had the same exact issue for an iOS app that uses EventKit.

I had crash with 10.0 simulator, with no XCode8 message on exit, while running smooth in 9.3 simulator.

I then added in info.plist the key NSCalendarsUsageDescription with a value string "Calendar access needed" (or whatever).

Tha app now runs.

Found here:

the related documentation.

Thanks to all for this thread that helped me to fix this issue.

I also experienced the similar crash for one of my app. It turned out to be that I need to set AppDelegate's Window property in didFinishLaunchingWithOptions. I don't know if this is an iOS 10 SDK bug or something new.
