Random crash from Supabase code right after app launch

[Kevin Lustgarten]

Bug report

Describe the bug

My iOS app that uses this package crashed a few seconds after launch. Upon reading through the crash stack trace, I noticed that this is happening due to some code from this package.

This happens very randomly (I can't manually reproduce this crash). However, I think (not 100% sure) this has happened when testing the app with bad reception, so that might be helpful here. I'll keep trying to reproduce this.

System information

• iOS: 17.2.1
• iPhone 14 Pro
• Supabase 2.2.1
• KeychainAccess 4.2.2

Hi @kevlust

Are you still facing this crash?

[Kevin Lustgarten]

@grdsdev I'm facing a similar, but different crash in version 2.9.0. I'll open a new issue about it!
