Hi.
An update.
I tried yesterday and today on an iPad .
Yesterday I has been able to install on iPad (iOS v.9.3.5) and the waiting time (sometimes, not all times) was about 1min 30s, so Debug Mode has been possible.
Today the waiting time on iPad has been every time a little more than 2 mins up to 4 mins, so the Debug Mode was not possible. Release Mode waiting time was about 10 to 15 minutes.
Today on iPhone (iOS v.8.4.1) waiting time in Debug Mode has been about 4 mins and in Release mode was about 12 minutes.
I have tried removing a great part of the data inside the code too, but this doesn't change the waiting time.
Turn off and on the devices doesn't change the waiting time.
But if I install a little example project, the waiting time is more or less 30 seconds.
What's wrong in my project?
Develop using Release Mode is not very easy.
I will try to obtain an iPhone 6 to test it.
Thanks to everyone.
