Re-sign IPA (iPhone)

http://www.enterpriseios.com/forum/topic/Resigning_3rd_party_apps

However, I am now doing on iOS 9 device and it show me this error when I drag and drop ipa file into device.

How shall I do?

Answer 1

This condition mainly occurs in phone with IOS9.Is it right?

IOS9 or XCode7 disables the unsafe HTTP requests,use https instead. You should update your system and Xcode to version7,then package your app again use xcode7.

If it works,recall me.

Answer 2

This problem can happen if there is an app on the device (possible the same app without the new signing) that has the same bundle ID as the re-signed IPA. Make sure you've deleted any old version of the app on the device and try again.
