Intercom iOS SDK 19.2.1 — Swift methods not recognized in SPM (loginUser and other APIs) | Community
Skip to main content

Hi Intercom team,

After updating our app to Intercom iOS SDK 19.2.1, several developers on our team started facing issues where Swift methods (like loginUser(with:), logout(), etc.) are no longer properly inferred or recognized by the compiler.


Details

  • Integration: Swift Package Manager (official repo intercom-ios-sp)

  • Project type: Pure Swift (no Objective-C bridging)

  • Issue: For some developers, Xcode shows only Objective-C versions of methods (e.g. loginUserWithUserAttributes:success:failure:).

  • Error: Cannot infer type of function call or No exact matches in call to function 'loginUser'

  • Behavior: Happens inconsistently across machines — some developers see the correct Swift interface and can compile fine, others cannot.

  • We already tried:

    • Clearing DerivedData & SPM caches

    • Re-adding the Intercom package

    • Confirmed same SDK version (19.2.1)

    • Still, the issue reappears randomly on some environments

 

Observation

When we “Jump to Definition,” for working setups it opens a Swift interface; for failing setups it shows Objective-C headers from the XCFramework.

This suggests the Swift module metadata might not be loading due to compiler version mismatch (Swift 5.9+ vs older/newer toolchains).

 

Any guidance would be appreciated — we want to confirm the officially supported Xcode versions or any upcoming patch addressing this SPM/Swift interface mismatch.

 

Thanks!
