Duplicate symbol when linking with Unity + ARKit

[swylietoal]

Expected behavior

Bugsnag is able to be added without needing code modification

Observed behavior

Bugsnag library conflicts with Unity ARKit plugin (StartSession)

Steps to reproduce

New Unity Project
Import ARKit plugin
Open Example Scene
Add Bugsnag
Run for iOS

• Xcode build fails with duplicate symbol linker error

Can't comment on Issues?

While not technically a blocking issue, this is definitely a friction point for on boarding new apps. Worked around by prefixing StartSession with BS_ in BugsnagUnity.mm and Bugsnag.cs - although a more elegant naming scheme may be better...

Thanks for the report, @swylietoal - can you paste a snippet of the exact wording of the error? This should be a fairly quick fix though I want to be sure there's no other underlying issues.

@kattrali I've encountered similar error.

duplicate symbol _StartSession in:
    /Users/megatron/Library/Developer/Xcode/DerivedData/Unity-iPhone-eizneylhlnjxjwdoxzyzwszpdrde/Build/Intermediates.noindex/Unity-iPhone.build/ReleaseForRunning-iphoneos/Unity-iPhone.build/Objects-normal/arm64/ARSessionNative.o
    /Users/megatron/Library/Developer/Xcode/DerivedData/Unity-iPhone-eizneylhlnjxjwdoxzyzwszpdrde/Build/Intermediates.noindex/Unity-iPhone.build/ReleaseForRunning-iphoneos/Unity-iPhone.build/Objects-normal/arm64/BugsnagUnity.o
ld: 1 duplicate sym

And if i understand correctly this function need renaming

Propably wise to append Bugsnag_ to all extern definitions.

Im having this same issue with Bugsnag 4.0. Any word on that?

@natalieSED Things have changed fairly significantly since this happened, can you open a new issue with the exact error message that you're seeing?
