iOS Question how to use sudo xcode-select -switch <path / to /> Xcode.app

[John Woodsmall]

sudo xcode-select -switch <path / to /> Xcode.app

how do i switch the xcode back to 8.0 (something)?

some how apple upgraded the system to 9.0 and now i can not upload to the store without error.

xcode-switch -p seems to point to the /../Xcode.app (which must be 9.0 of xcode) but:

So where is the 8.0 of xcode? and what are the exact words that i type in?

You should first install Xcode 8.
