App Crashes From ipa file but runs fine from Xcode?

Question

When I run my project directly from Xcode to my device it runs perfect without any crashes. But when I create an ipa file of that project and install that ipa into my device by using iTunes, when i click on the login button it crashes,later so many tries for logins after that it works fine.

if refer this issue on internet by it doesn't help for me. this are the links i refer

App works fine with developer build with xcode. But crashes when run using ipa file

Gameplay Crashes From ipa file but runs fine from Xcode?

i don't understand what is the actual problem with the achieve ipa file. why it does not crashes when I run it directly from Xcode. Is there any code compression or different mechanism of code compilation when running as an ipa or from Xcode.

Any help would be appreciated.

Answer 1

You should look at the crashing logs.

1. connect you device to you Mac
2. in Xcode, press cmd+shift+2.
3. find you device, and press the log button
4. wait a while. then you can see all crashing logs.
5. find the ones with your app's name. If you don't understand it, post it here.

Answer 2

I have also gone through same issue

You have to edit your scheme

Archive --> Build Configuration --> set this to Debug Try to archive and test your IPA now.. it should work fine.

Answer 3

I assume that you build your app with different build configurations basically using the Debug configuration when you run it from Xcode and the Release configuration for deployment as ipa. We had a similar issue with unexplainable bugs in the release configuration and figured out that the Swift Optimization caused the problem. For now we switched from Fast, Whole Module Optimization to Fast, Single-File Optimization for the release builds until we can narrow down the problem.

Hope that helps!
