iPhone App installs to 90% and then dies

Question

I am trying to install an app from TestFlight. It installs to 90% and then it just fails.

Does anyone have any ideas?

Answer 1

When the application download hits 90% it generally means the download has completed and iOS was unable to extract and install the build.

There are many reasons why this happens, most of which we catch with upload or install time validations, unfortunately there are a few cases we do not or are unable to detect.

Here is our help article discussing some of the scenarios.
