Description

The build of Flipper-Glog (0.3.6) using 'pod install' fails if the Xcode application name contains a blank space.

Steps To Reproduce

1) Name the Xcode application something like 'Xcode-beta 12.0'.
2) Run: sudo xcode-select --switch /Applications/Xcode-beta\ 12.0.app
3) Run: pod install

Expected Results

I would expect Flipper-Glog (0.3.6) to build properly, whatever the Xcode application name is.

Instead, it fails as follows:

See `config.log' for more details

This seems due to the configure script not being able to handle spaces in the application name (and it's probably true for other unusual characters too).

Encountered a same error message, but Xcode application name doesn't contain a black space.

That's really weird, but just renaming the Xcode, removing the blank space worked for me as well.

It's actually not that weird. If the application name is not properly quoted in the script, the blank space will break the syntax and the script will fail.
