Xcode 10.1: Profile is Not an ‘iOS In House’ Profile – Developer Program Guide

The answer is almost YES!

I managed to install new builds of the same app on the devices via Fabric.io without apple dev subscription. (I guess you can also distribute them with iTunes. Send ipa to tester, and it should be able to install it via iTunes.)

The only disadvantage is that you have to connect the device to Xcode at least once. Then you can remotely install new versions. (I didn't find the way to do it manually knowing the udid)

When you connect the "unknown" device to xcode 7, there is a fix issue button in Target general settings. Fix the issue and Xcode will generate a new Provisioning profile with this device included. (you can find it in ~/Library/MobileDevice/Provisioning Profiles)

Than you can use this provisioning profile to distribute apps via Fabric.io

1. Signup on Fabric.io
2. Setup Fabric for your project (there is a step by step guide)
3. Make sure that xcode uses right prov. profile to sign it. Automatic worked for me.
4. Xcode>project>archive
5. fabric helper will detect the build and you will be able to distribute it.

Sorry guys who are not proficient enough with Xcode, I don't have much time to add less error prone guide, but I hope this answer will help somebody with ideas.

TIP: use this quicklook plugin to see inside ipas and prov. profiles!

You can deploy to your personal devices as many times as you want; there's no restriction on deploys of this type.

You only have to pay the membership fee if you want to use the more advanced features such as TestFlight and the App Store.

Update:

• Here's a list of supported capabilities that require either a free account or paid one.
• The provisioning profile is only good for 7 days. After that you need to generate a new one and deploy it to the device.
• Max number of connected devices is limited to 3.
