I am stuck with this for last 1 week. Any help is appreciated.

can you please add your project to github and post the link. — rshankar
I suggest you reformat your hideously formatted error message. Putting it in a code block should make it readable. — Mark Amery

Can you please try give the publishable key under Stripe.m, you can get publishable key from Stripe -> Account Settings -> API

static NSString *defaultKey =

Since I have used a test card starting with 4242, I get an alert message with "Payment Not Successful"

Hope this helps.
