UID2Prebid SPM build fails: PrebidMobile 3.3.1 requires iOS 13 but package declares iOS 12 #87
Description
Summary
Adding uid2-ios-sdk via SPM and linking the UID2Prebid product fails to build when the
app target's minimum deployment is iOS 12, producing:
The package product 'PrebidMobile' requires minimum platform version 13.0 for the iOS
platform, but this target supports 12.0
Root Cause
Package.swift declares .iOS(.v12) as the minimum platform, but latest PrebidMobile package
(added in #80) requires .iOS(.v13). SPM enforces that all products in the dependency
graph satisfy the declared minimum, so UID2Prebid, which links PrebidMobile cannot
resolve.
Steps to Reproduce
- Create an Xcode project.
- Add
https://github.com/IABTechLab/uid2-ios-sdkvia SPM. - Add
UID2Prebidto the target's linked frameworks. - Build.
Expected Behavior
Build succeeds, or a clear compile-time error explains the iOS 13 requirement.
Actual Behavior
SPM emits the platform version conflict error above and the build fails.
Suggested Fix
Bump the minimum platform in Package.swift to .iOS(.v13) (and .tvOS(.v13)) if possible.
Environment
uid2-ios-sdkversion: 2.1.0 (latest)prebid-mobile-iosversion: 3.3.1 (latest, pulled via.upToNextMajor(from: "3.1.0"))- Xcode: 16.x
- Swift tools version: 5.8

Hi @abdulmedzid thank you for bringing our attention to this issue. I have made a fix and will make a new software release on cocoapod tomorrow.

Hi @sunnywu thank you for a quick update. The platform version mismatch from the original issue has been resolved, but when updating to 3.0.0 i found a new compilation error in
UID2Prebid.swiftat line 83.Error:
Location:
Sources/UID2Prebid/UID2Prebid.swift:83Cause: In some of the latest versions of PrebidMobile they made a breaking change and renamed the
idparameter touniqueIdin theUserUniqueIDinitializer. The current code uses the old.init(id:aType:)signature which no longer exists, causing the compiler to fail to resolve the type.Fix: Update line 83 to use the renamed parameter:

@sunnywu thank you for a quick fix, I have tested the SDK through swift package manager and didn't encounter any issues.
