Realm-cocoa: Failed install of sync dependency when XCode.app is named differently

[cowgp]

Goals

Have multiple version of XCode installed at the same time and still be able to install realm dependency via cocoapods

Expected Results

pod install succeeds

Actual Results

pod install fails with

Installing Realm 5.4.7 (was 4.4.0 and source changed to `https://cdn.cocoapods.org/` from `trunk`)
[!] /bin/bash -c 
set -e
sh build.sh cocoapods-setup

Downloading dependency: sync 5.0.28 from https://static.realm.io/downloads/sync/realm-sync-cocoa-5.0.28.tar.xz
clang: error: no such file or directory: '12.0.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator14.0.sdk'
clang: warning: no such sysroot directory: '/Applications/Xcode' [-Wmissing-sysroot]

Steps for others to Reproduce

When preparing to update to new version of XCode I have my currently stable support version named XCode.app and then download and place in my applications folder addition version(s) of XCode but modify their app names to include version. For example in my applications folder I currently have:

• XCode
• XCode 11.3.1
• XCode 12.0

If there is a space in the name of the currently in use version of XCode - then the error occurs.

Easy workaround is to not use spaces in app name.

Version of Realm and Tooling

Realm framework version: 5.4.7

Realm Object Server version: ?

Xcode version: 12.0

iOS/OSX version: 10.15.6

Dependency manager + version: 1.9.3

Obviously we should fix this, but I definitely would recommend avoiding spaces in your Xcode app names.

Yes, I'm in no way blocked by this - just thought I'd point it out.
