I used to create the ipa file from Xcode/Product/Archive and install it via iTunes. After updating the iPad to iOS 9.3.1, the app keeps showing "Installing" in iTunes and disappears the installing icon on iPad after loading but never completed. With the Build and run the current scheme option, this app can install on iPad.
I had already updated my Xcode to 7.3 and iTunes. Any solutions to fix it? Thanks.
