Results polluted by previous runs

[MontakOleg]

Hey again, @marinofelipe 👋

I noticed that several runs on different projects affects results.

For example: swift-package-info --for https://github.com/ReactiveX/RxSwift --product RxCocoa EmptyApp size on disk: 2.6MB App with RxCocoa size on disk: 4.3MB Increase: 1.6 MB

swift-package-info --for https://github.com/ReactiveX/RxSwift --product RxSwift EmptyApp size on disk: 4.3MB App with RxSwift size on disk: 4.3MB Increase: Zero KB

(in example we use same project with different products, but same right for different repos too)

This is because each run reuse same directory for EmptyApp:

Cloning empty app

Running Shell command

fatal: destination path 'swift-package-info' already exists and is not an empty directory.

Finished Shell command

Hey @MontakOleg , thanks again, it's nice to have you contributing so much 😄 . Which version are you using? This should be fixed from latest release 🤔 .

The empty app is cloned into a temporary directory that shouldn't leave trails nor impact other measurements.

This is the result I get when running on v 1.0.5, on command after the other:

swift-package-info --for https://github.com/ReactiveX/RxSwift --product RxCocoa

Your output contains: [7/7] Reseting and cleaning up empty app... step, which missing in my output. Looks like this step was removed in https://github.com/marinofelipe/swift-package-info/commit/045a08fe0d17b142af3fc63f6fee8c1e7a9007c3.

The empty app is cloned into a temporary directory that shouldn't leave trails nor impact other measurements.

As I can see fileManager.temporaryDirectory point to same directory each run (/var/folders/gz/k5y4mzt57vl1ppy0n_4qtdw80000gn/T in my case)

Ohhh, good catch. I wasn't testing on latest version 🙈 . I can now definitely reproduce the same behavior. Cool, I'll look into the PR you opened up 👍 .
