Apple development profile required when building ios app

My first demo application works well on the ios simulator. Now I try to test this application on an iPad. I checked nearly everything: bundle identifier, team, build for… The iPad is visible on the Run to button… I checked all Xojo tutorials and documents and read all user support topics. Where can I check/create my Apple development profile?

Jeremie, do you need to enroll for the Apple Development program and purchase a one-year membership? Do you need to enroll for the Apple program just for testing purposes?
