How to fix iTunes Connect error ‘No identities are available for signing’, This error appear every time you are trying to upload your iOS App binary from Xcode to iTunes Connect for Apple App Store Distribution

Mandar Apte Apple, Apple iOS, Apple Xcode Leave a comment

The issue of ‘No identities are available for signing’ starts with default behaviour of Xcode when you create new app in Xcode itself,

You fill up following information in Xcode while creating new app for iOS,

 
creat new project xcode ios bundle idetifier organisation idetifier product name

 
i.e. Product Name, Organisation Name, Company Identifier & it generates bundle identifier based on your inputs

Apple blindly by default & forcefully inserts ‘Product Name’ in bundle identifier without prompt or even asking user about it they want it or not.

So when you ignore this situation & start building your App…

At time of uploading your app to Apple App Store through iTunes Connect i.e. ITC it throws following error at you

 
No identities are available for signing itunes connect itc error apple app store

 

Error Name: No identities are available for signing

 
So here is work around & solution for this error:
