Unable to build with Xcode

[TechGeekGamer]

Hello! I was trying to build your project in Xcode using your provided guide in the README, but keep getting an error. If it's helpful to know, I am using Xcode Version 15.4 (15F31d) on a Macbook Pro running macOS Sonoma 14.5 (23F79). Here is the error I am getting:

AmpFin/AmpFinKit/Sources/AFFoundation/Item.swift

I am on the latest commit (d823cb72fc6bd528bbf3d3d99f7bc5b681604680) and have not made any changes to the codebase besides the Debug.xconfig and removing the Siri entitlement (because otherwise it'd error, because I have a non-paid developer member account).

Could you let me know where I may be going wrong by missing a step or something? Thanks in advance!

Hey,

i am currently using the Xcode 16 beta and the latest MacOS public beta and it seems like older toolchains have a problem building AmpFin. Here are the modifications I had to make to be able to build the project using the latest stable tools:
