Slow bundle copy build phase when archiving iOS Widget Extension

[Mordil]

Question

We have an iOS Widget extension target that is compiled with our main iOS app target, and during its build, we see the following logs

[08:35:38]: ▸ [AthensWidgetsExtension] Copy Apollo_ApolloAPI.bundle -> Apollo_ApolloAPI.bundle
[08:35:38]: ▸ [AthensWidgetsExtension] Copy Apollo_Apollo.bundle -> Apollo_Apollo.bundle
[08:50:37]: ▸ [AthensWidgetsExtension] Processing Info.plist
[08:50:37]: ▸ [AthensWidgetsExtension] Copy arm64-apple-ios.abi.json -> AthensWidgetsExtension.abi.json

Notice the Copy Apollo_Apollo.bundle step takes almost 15 minutes!

That same step for the main iOS target is effectively instantaneous.

Apollo is pulled in to both target via our shared umbrella Swift Package that has Apollo as a dependency.

I'm at a loss to determine what could be causing this - is this something others have encountered?

This is accounting for 50% of our build times

Hi @Mordil - it's an odd one for sure, I don't believe I've seen any other reports of this kind of behaviour unfortunately.

Is it possibly an Xcode thing, i.e.: Do you notice this across different versions of Xcode too?

The logs I posted were with Xcode 15.2.

I ran builds with Xcode 15.4 & 16.2:

• 15.4 => took ~ 14 minutes
• 16.2 => took ~ 12 minutes
