Why do I need to trust the developer?

Good question. As you are installing apps are from third-party sources (you install them via Safari or Xcode/Cydia Impactor) and not from the official App Store, Apple cannot verify it’s authenticity or take full control of them.

That is why when you open the apps for the first time after installing them from third party app store, Apple is shows you this message. Apple just wants to make sure that you are completely aware of what you are doing. If you believe the app will not negatively affect your device in any way, then you can trust the developer yourself (by following a few simple steps) and by doing so, you take full responsibility for doing that.

Making “Untrusted Developer” in to “Trusted Developer” on your iPhone is as easy as it gets. We will show you how to do that and how fix “Untrusted Enterprise Developer” error in the following section.

How to Trust “Untrusted Enterprise Developer” on iPhone

Till iOS 8, the “Untrusted Enterprise Developer” error message also came with an option to trust that particular developer right from the pop-up message. Starting iOS 9 and above, Apple has made changes around this and now, you have to go the Settings app and find the app profile. Here are the detailed instructions:

  1. Go to Settings > General > Profile & Device Management
  2. Under the ENTERPRISE APP section, find the app profile that belongs to the app you’ve installed.
  3. Once you locate it, open the profile, tap on the Trust button, and one more time to confirm.
  4. Done. Now you can return to the Home screen and launch the app and starting using it without any restrictions.

After you complete the above steps, you should now be able to open and use the app which you had downloaded from the third party app store on your iOS device such as iPhone or iPad.

Attention!

If there is no Trust button in the profile page but you find a new Verify button instead, it’s more likely that the app’s certificate has expired. In this scenario, the Verify button will probably not work and you will have to reinstall the app to get it working again.
