- on Xcode 9.0.x stack Xcode Archive took 188 secs

Solution: turn off the **Compile Bitcode** option in **Xcode Archive** step

```auto
    - xcode-archive:
        inputs:
        - upload_bitcode: 'no'
        - compile_bitcode: 'no'

```

With this the Xcode Archive step took 48 seconds on Xcode 9.0.x in the quick test build.

Explanation: **Xcode 9 changed the default configs regarding Bitcode** in archive for Development / Ad-Hoc archives.

Xcode 8.3 did not use the Bitcode option during export _if the export type is `development` / `ad-hoc`_, but Xcode 9 does, so if you want to make the archive faster and you don’t need Bitcode you should disable that in the Xcode Archive step.

_This only applies for non App Store archives, for app-store type archives Xcode 8.3 did enable Bitcode as well by default, so there should be no (significant) difference on the two stacks._
