调试时应用程序不会崩溃

Question

I am facing a strange issue in my currently working app. App is crashing when we install app through diawi or directly install using .ipa . But I am not able to regenerate the issue through debugging. I am totally confused and how can I solve the issue?

I am using Xcode 8.2.1

Answer 1

You can try building the app in Xcode in the Release configuration instead of the Debug configuration.

You do this by

• clicking on your app name at the top left (near where you press to run the app)
• choosing 'Edit Scheme' from the drop down
• clicking on the disclosure indicator by 'Run'
• choosing 'Run' from the three choices which appear
• there is a drop down called 'Build Configuration'. This will almost certainly be set to Debug. Set this to Release.

Now when you run your app you will be building a far more optimised version - this is the version you build when you are submitting to Apple. It's just the same app optimised for speed/memory instead of debugability.

Hopefully, you should be able to reproduce your crash in Xcode now. However, you'll notice that you get far less debugging information when you hit your crash - this is because Debug builds have lots of extra information in (and are much less optimised by the compiler) specifically to make debugging easier. Being able to reproduce the crash in Xcode should give you a few more clues as to what's going on. At the least you should be able to see the chunk of code causing you issues.

Let us know how you get on.
