iOS Question Crash in app but not debug mode

[Bruno.im]

My App runs fine in debug mode, nothing in the log but when I compile the release app it crashes. How can I find the problem?

Does it immediately crash?

No, the app open, show the main page then when I click on the calculate button it crashes.
