I remember reading something once, but could not find it now while searching, if there are things I need to worry about when installing an iOS beta.
If I install the iOS 6 beta, do I need to worry about it overwriting my current Xcode 4.2 (iOS 5.1) development? Or does it install it in a separate location automatically? Or is that all I need to do, in that I need to put it in a separate location when installing instead of the default location?
If I put a device on iOS 6 beta, it cannot be downgraded back to 5.1 right?
Are those the only things I need to worry about? Thanks!
As Apple states in the Xcode 4.5 Developer Preview Release Notes[1]: Xcode 4.5 comes as a single app bundle that can simply be dragged to the Applications folder. You can start it from there and it will not install or overwrite any existing developer tools like previous Xcode versions.
Apple states that
But you may be able to downgrade your iOS device as long as version 5.1 is the official version served by apple by putting your device in the DFU mode. When Apple pushes iOS 6 for everyone you may be able to downgrade your device with TinyUmbrella[2]. This worked with previous versions but there is no guarantee it will work this time.
