SPM binary target checksum mismatch in 5.2.16 (and 5.2.15)

[andrii-ae]

Description

When resolving Swift Package Manager dependencies for version 5.2.16 (and 5.2.15), the checksums of the downloaded binary targets don't match the checksums specified in Package.swift.

Error Message

checksum of downloaded artifact of binary target 'OneSignalLocation' (efa24b15c8e321aa2768853ce90406af257aded6d87b54461a183aac2592cf36) does not match checksum specified by the manifest (bc5a812dc5b55880570867aeae54e93c686108b45ade0275e5fca03b755741cf)

This affects all binary targets in the package.

Expected vs Actual Checksums

Binary Target	Package.swift Checksum	Actual Download Checksum
OneSignalLocation	bc5a812d...	efa24b15...
OneSignalFramework	0b40df3b...	07405de4...
(all other targets similarly affected)

Steps to Reproduce

1. Add OneSignal-iOS-SDK as SPM dependency
2. Specify version 5.2.15 or 5.2.16
3. Run xcodebuild -resolvePackageDependencies

Impact

All iOS projects using OneSignal via SPM cannot build.

Suggested Fix

The checksums in Package.swift need to be updated to match the actual binaries on GitHub Releases.

same error here. havent found a solution. Cannot build app

downgrading and cleaning cmd+k and cache still gave me errors. This fixed it:

The Problem:
Xcode's SPM cache got into a corrupted/inconsistent state. Even after you "Reset Package Caches" in the UI, Xcode was still holding onto bad state internally. The GUI kept failing before it could even attempt to download packages.

The Fix:

1. Killed Xcode completely (killall Xcode)
2. Nuked ALL SPM caches - not just the project ones:
   - ~/Library/Caches/org.swift.swiftpm
   - ~/Library/org.swift.swiftpm
   - ~/Library/Developer/Xcode/DerivedData/Pretzel-*
   - Package.resolved file
3. Resolved via command line (xcodebuild -resolvePackageDependencies) which bypasses Xcode's buggy GUI state

About versions:

• You're on 5.2.14 now which resolved successfully
• 5.2.15 and 5.2.16 have broken checksums (confirmed bug in GitHub issue SPM binary target checksum mismatch in 5.2.16 (and 5.2.15) #1633)
• Don't update OneSignal until they fix that issue
