fatal error: module map file [...]realm-swift/build/GeneratedModuleMaps-iphoneos/Bid.modulemap' not found

Expected results

compile using Realm with SPM (no pod or carthage).

Actual Results

Compile fails

Steps & Code to Reproduce

I got ride of using carthage in my iOS project. Now I'm trying to use spm to include Realm instead to simplify the build system. (tried both Realm 10.20.0 and 10.22.0). I'm using Xcode (13.2.1) GUI to do this. xcode-select point to the right version of xcode.

it fails when using xcodebuild command to create a framework for simulator instead of building inside xcode.

the command that is run: xcrun xcodebuild -project myFramework.xcodeproj -configuration Debug -destination platform=iOS Simulator,name=iPhone 8,OS=15.2

1. First, I'm getting 2 warnings (no biggy):

2. I'm getting errors:

Core version

Core version: ? Realm 10.20.0

Intersting tidbits: building inside xcode 13.2.1 on Mac OS running Big Sur for simulator: using spm with Realm 10.22.0, xcode manage to compile each target fine (albeit the 2 warnings above).

When doing the same build using xcodebuild, I get the error above. Bid.modulemap is only found in real-core but not in realm-swift.

I reset packages and cleaned DerivedData while xcode down many times...

Bug with spm ?

[ericjordanmossman]

I'm seeing the same thing. Will keep looking into this more.

[ericjordanmossman]

I created https://bugs.swift.org/browse/SR-15840.

[kcchu]

I'm seeing the same error as well.

[palaniraja]

I see the same issue when i am building manually(sh build.sh build) as well with xcode 13.2.1 (realmswift v10.1.4)

@pitoneux this is easily fixable by declaring the schema when using the xcodebuild command, so you can use the following command instead xcrun xcodebuild -project myFramework.xcodeproj -schema yourSchema -configuration Debug -destination platform=iOS Simulator,name=iPhone 8,OS=15.2. You can get a list of the projects schemas using xcodebuild -list. This issue clearly is an xcodebuild issue which we reported to Apple in the above mentioned radar.

@palaniraja sh build.sh build. is currently working fine for our latest release (10.40.0) and tested on latest Xcode version (14.3.1).
