Check for possible build optimizations #1063

Closed defagos closed 2 weeks ago

defagos commented 2 weeks ago

As a developer integrating Pillarbox I would like Pillarbox to compile quickly so that the associated footprint is minimal. As a Pillarbox developer I would like Pillarbox to compile as fast as possible, demo included, so that I can be more efficient when building from scratch or for CI purposes.

Acceptance criteria

Possible build optimizations have been made.

Tasks

[x] Investigate build performance.
[x] Optimize where possible.

We can tweak warnings for long compilation times by locally adding the following flags to our Package.swift manifest:

swiftSettings: [
    .unsafeFlags(["-Xfrontend", "-warn-long-function-bodies=100"]),
    .unsafeFlags(["-Xfrontend", "-warn-long-expression-type-checking=100"])
]

Same by adding the flags to the Pillarbox demo settings.

There is no severe issue with the current code. Everything compiles fine.

On my M1 Max the overhead associated with the inclusion of Pillarbox and its dependencies in a minimal project is ~5 seconds.

Should be pretty much under control for the moment. Closed.
