How to send a build on TestFlight

We can send a build on TestFlight to client or for testing purpose. It is a simple way to distribute our apps. So for sending our on TestFlight we have to follow following steps:

• Firstly we have to create Distribution cretificate for the app and select the distribution certificate by going to Target > Build Setting > Code signing.
• Next step is to create archive we can be created by going to Product > Archive.

• It will take sometime after creating archive Click on Upload to App Store. Then a pop up will appear in which we have to select developer account and click Choose.

• Now after sometime this screen will come with your project, click Upload.

• If you have to add the tester to send the build then you must go on Users and Roles and add a user which requires First name, Last name, and the user's apple ID after adding the user an email will be sent to that person for confirmation. When that person confirm his email then you can send him build for testing.
• For sending build to the user you have to go My Apps and then to your app, then to Test Flight and then to Internal Testing.

• If the tester is not present in the list you can add by + option after that select the build version which you want to send to the user and then select OK. Now build has been sent to user he must be notified about it.
