I use terminal create podfile:
$ cd /Users/user_name/Desktop/CocoaPodsTest
$ touch Podfile
but i can't find podfile in finder ,but i can use 'vim podfile' to edit it. and when i install podfile , it shows this information:
[!] Could not automatically select an Xcode project. Specify one in your Podfile like so:
project 'path/to/Project.xcodeproj'
when i restart my mac , if i install pod,it show this pod has not exists!
it happens from i update xcode version to 8.0.
Use command pod init to create a podfile.
$ pod init
Tip: CocoaPods provides a pod init command to create a Podfile with smart defaults. You should use it.
