I have created an IPA file for my app, and I would like to test it on different devices.
I don't have apple developer account yet (i will purchase it once tests will be fully successful).
I installed the app with Xcode to my IPhone successfully, but I cannot do the same on other IPhones... I tried to sign the IPA with the IPhone owner account, but i got the same error message : "Unable to install "app.ipa""
Do you have any idea what could be the error and how i could solve this ? Purchase apple developer account is the only solution ? Even for testing ?
