[awaik]

Hi!

When I try to run the code under iOS I got an error

code

final mnemonic =
        await Mnemonic.fromString('puppy interest whip tonight dad never sudden response push zone pig patch');

error

Just tried this, not able to reproduce. Let me know if you are using a simulator or device, and environment details.

You can also try flutter clean and then flutter pub get and run again

Have you been able to run the example app?

[awaik]

Hi! Thanks, complete clean + pod update fixed the issue, thank you!

[awaik]

Nope, same error again. Should I do some additional installation for the iOS?

1. I've checked - the example app works.
2. If I copy-paste the code to my app it returns this error.

I found the reason, how to reproduce the bug:

1. example app
2. create a scheme (flavor) under ios, two gifs, takes 3 mins:

   • https://miro.medium.com/max/1400/1*XsDo_Kv4UPiS-Qeix9YEEA.gif
3. run this flavor flutter run --flavor dev

We got the error

@awaik Was this resolved?

[awaik]

@BitcoinZavior Nope, for avoiding confusion because of the wrong first message, before I found the exact reason, I made a new issue https://github.com/LtbLightning/bdk-flutter/issues/52
