Apple Mach-O Linker Error with UnityAds in 5.5.0f3

At the moment Xcode does not build the game to push to my device.

I get 344 warnings (even after 'Updating to the recommended settings') and the following error:

Potentially relevant Unity Player Settings:

• Scripting Backend: IL2CPP Target

• Device: iPhone + iPad Target SDK:

• Device SDK Architecture: Universal

• Api Compatibility Level: .NET 2.0

Xcode 8.2.1 Potentially Relevant Information:

• Architectures: Standard Architectures

• Base SDK: Lastest iOS (iOS 10.2)

• Supported Platforms: iphoneos

• Valid Architecture: arm64 armv7 armv7s

From the error it seems that I need to delete one of the 'UnityAdsUnityWrapper-B8F6576517066FC0.o' and one of the ''UnityAdsUnityWrapper-6D362980BD529555.o'.

However I am unsure which to delete and how to delete it, if that even is the issue. Deleting the UnityAds folder in the build doesn't seem to help.

Any help would be appreciated, thank you.
