Answer 1

Just execute the below command and you should be good to go:

sudo xcode-select --switch /Applications/Xcode.app

Answer 2

Looking at the error logs:

checking for arm-apple-darwin-gcc... /Library/Developer/CommandLineTools/usr/bin/cc -arch armv7 -isysroot  checking whether the C compiler works... no xcrun: error: SDK "iphoneos" cannot be located xcrun: error: SDK "iphoneos" cannot be located xcrun: error: SDK "iphoneos" cannot be located xcrun: error: unable to lookup item 'Path' in SDK 'iphoneos' 

There is the same kind of error on this link.

You either need to do a xcode-select, or at least in XCode, Preferences/Locations/Command Line Tools, I guess.
