Error itms 90035- invalid signature. A sealed resource is missing or invalid

[RohanSampat]

When I use this Swift 4 support package in my project, it builds without any error but when i try to upload it to app store it states error items-90035: Invalid signature. A sealed resource is missing or invalid.

I m using correct certificate & provision profile but using this package messes up my certificate.
