Hi @dipkasyap

If I open the example app, and run it, I do not see any crashes.

Please provide information on how to reproduce this issue. That involves:

• iOS version
• device or simulator (or both)
• code
• maybe even an example project

Probably the easiest would be to replicate it in the example project

[dipkasyap]

Sure , i will get to you soon

Please review if the log helps some how
