So I'm not using enterprise distribution profile to archive and export my project into IPA file.
I am using a valid distribution certificate though.
On XCode organizer I've made sure that everything is valid by clicking on the validate button for my particular archive before exporting it using the exact same distribution certificate and distribution provisioning profile. Also, I've made sure that I checked App Store as the method of distribution.
So I assumed everything checked out, then I distributed the IPA through diawi.
This is what I used to distribute my development IPA at the early stage of this project. However, upon opening the diawi link, installation just failed on my device saying "Unable to download" every single time.
Now I'm just wondering is it not at all possible to distribute through diawi if I'm not using enterprise distribution profile to build the ipa itself?
Or am I building it the wrong way for the intended purpose?
I'm very new to this whole Apple environment so not sure if I'm understanding the process correctly. I'm developing this from a react native project in case you need to know.
Thanks in advance for any pointers! :D
EDIT:
There seems to be confusion in the answers so far. Just to clarify, I'm NOT using enterprise distribution profile nor I am using development provisioning profile. So adding UDID to the provisioning profile is not an option. The case I'm asking about is for ipa signed with app store distribution provisioning profile which I'm trying to share using diawi. It doesn't seem to be possible to distribute ipa signed this way with diawi based on my research, but I just wanna be extra sure. Sorry for the confusion. :)
You need to have the UDID of downloading device added to the provisional profile. Login to your apple developer account and check if the device is added or no. If not add that device and then update the provisional profile by selecting that new UDID. Download the updated profile and the build.
