I just want to add new device UDID to an existing provisioning profile, to modify the provisioning profile i clicked "Generate" but its showing to download, there is no way to add devices there... please consider my problem respond to me . thank you in advance.
First add the device udid in devices list by clicking on '+' button in the devices list. Then, after adding device udid, go to the provisioning profile list. There, select the provisioning profile to which you want to add the device. Afterwards, you get an edit option that you want to use for adding the new UDID, which you previously added to the devices list. You find this option at the bottom.
After clicking edit button we have an option to select device udids
I hope this will help you
Note: initially while creating provisioning profile we have to add atleast one device id else we dont have add device option in edit mode.( If device count is '0' (from screen shot) then we dont option to add devices)
Go to the devices setting in https://developer.apple.com/account/ios/device/deviceList.action and see how many devices are added in your account after that add the additional devices UDID and save that.
Now when you come back to the provisioning profiles then you will see the devices you just added. You can select all the devices and then press generate. Now you can easily download the updated provisioning profile.
Hope this helps.
Note that testers are no longer added via UUID in the new Apple TestFlight.
Test Flight builds now require an App Store Distribution Provisioning Profile. The portal does not allow UUIDs to be added to this type of provisioning profile.
Instead, add "Internal Testers" via iTunes Connect:
Internal testers are iTunes Connect users with the Admin or Technical role. They can be added in Users and Roles.
After adding a user, be sure to click on their name and flip the "Internal Tester" switch.
Then, go to App > Prerelease > Internal Testers
and invite them to the build.
