iOS 应用安装失败原因排查
一：我遇到的问题排查：

Most common causes of this issue:
Device storage is full
The provisioning profile is a developer provisioning profile
The ad hoc distribution provisioning profile is corrupted and the device is having an issue with it.
The device was restored from a backup and is causing a conflict for over-the-air distribution
There was a network timeout
Architecture settings of the build and the device are incompatible ( can sometimes happen when "Build Active Architecture Only" is on when building).
Not Using Mobile Safari.
To find out the exact cause of this issue:
Connect the device with iMac.
Open Organizer then choose devices.
Choose your Connected device from sidebar.
Choose Console inside the chosen device.
Now install the app it will show the exact cause of problem

顺带看了一下其他可能的问题：
不抄了直接给几个比较好的链接：
