Extended package resolution time via SPM

[mitschlagel]

Hello

When resolving dependencies, RxDataSources takes significantly longer than all other dependencies to resolve, sometimes hanging and never resolving.

When resolving via command line, we often get the following:

Checking out 5.0.2 of package ‘RxDataSources’ Couldn’t update repository submodules: Submodule 'Carthage/Checkouts/RxSwift' (https://github.com/ReactiveX/RxSwift.git) registered for path 'Carthage/Checkouts/RxSwift' Cloning into '/Users/346352/Library/Developer/Xcode/DerivedData/FNB-Beta-aphmtxtcxvdndkcwaaysglkzgjyz/SourcePackages/checkouts/RxDataSources/Carthage/Checkouts/RxSwift'... fatal: --stdin requires a git repository fatal: fetch-pack: invalid index-pack output fatal: clone of 'https://github.com/ReactiveX/RxSwift.git' into submodule path '/Users/346352/Library/Developer/Xcode/DerivedData/FNB-Beta-aphmtxtcxvdndkcwaaysglkzgjyz/SourcePackages/checkouts/RxDataSources/Carthage/Checkouts/RxSwift' failed Failed to clone 'Carthage/Checkouts/RxSwift'.

Steps taken so far:

1. Reset package caches
2. restarting xcode many times
3. clean build + deleting derived data
4. remove dependency and re-add

We are using 5.0.2.

Thanks.
