I have integrated Fabric Crashlytics sdk with my ios application, using the Fabric mac desktop app. I archive my application using the free apple developer account. I uploaded the application using Fabric desktop app. Setup with my email. open the email on my iPhone and setup the fabric Beta webhooks. But whenever i keep trying to download and install my application. it will ends with unable to download app dialog.
Mike from Fabric here. If you have a free Apple Developer account, you can only install the app directly on your device via Xcode. This is a restriction of the membership. You can test on your one device registered via Xcode and only when distributed from Xcode to your device directly.
You need an Apple Individual, Organization, or Enterprise account in order to distribute to devices.
