2. Start ABB

Observed behaviour

ABB crashes during start-up

Expected behaviour

ABB doesn't crash during start-up

iPad Pro - iOS 10.2 (physical) does not crash

[pavelz]

Dependency framework AttributedMarkdown was left to default "deployment target" which rendered to 10.2. ABB app itself is still set to and supporting down to 8.0

[pavelz]

Still crashes in bootstrap on 8.4.1 (Salsita iPhone 5c). See the attached log.
I could not reproduce it through sideload debugging.

Sorry wrong log, incomplete symbols, see the next one.

• For the most part, all devices listed below are still crashing with the latest 1.5.2-devbuild (1431), but as mentioned before, the behavior with the iOS 8 devices are slightly different. The iOS 8 devices mostly don't load either and crash, but 1 out of 5 times or so, the app actually loads (unlike the ioS9.0+ devices where the crash immediately 100% of the time).

No crash reports were prompted to be sent.

@scheer please retest build 1435
​https://rink.hockeyapp.net/manage/apps/185237/app_versions/110
I have just published it.
I will not close the issue as usual and leave it to the result of retesting

[pavelz]

Alright closing as usual, to signal retestability. Also added Scott to cc. I still don't remember if being an appointed tester means that the person is being cced or not.

Below are the results of the new test run on TO. As you can see, there appears to be an issue TO side with regards to the app initialising on VM startup, of which we need to look into. Although my results state 'works on startup 3/5 etc', the true fact is that this issue is now resolved, as the app actually starts, which was the point of this issue in the first place.
