ios – Swift ‘pod trunk push’ Error Finding File

I am trying to publish my library, and when I run: pod lib lint
I get SwiftUIHelper passed validation.

but when I do pod trunk push I get some errors:

 -> SwiftUIHelper (0.0.1)
    - WARN  | [iOS] license: Unable to find a license file
    - ERROR | [iOS] xcodebuild: Returned an unsuccessful exit code. You can use `--verbose` for more information.
    - NOTE  | xcodebuild:  note: Using codesigning identity override: -
    - NOTE  | [iOS] xcodebuild:  note: Building targets in dependency order
    - NOTE  | [iOS] xcodebuild:  note: Target dependency graph (3 targets)
    - ERROR | xcodebuild:  SwiftUIHelper/SwiftHelper/Features.swift:24:13: error: cannot find 'ButtonListView' in scope

The file Features doesn’t exist anywhere in my project. I’ve tried deleting derived data and cleaning build folder but the errors persist. This is my .podspec file:

Pod::Spec.new do |spec|

  spec.name         = "SwiftUIHelper"
  spec.version      = "0.0.1"
  spec.summary      = "A pod with Swift & SwiftUI Helpers"

  spec.description  = <<-DESC
This CocoaPods library helps you do SwiftUI things.
                   DESC

  spec.homepage     = "https://github.com/***/SwiftUIHelper"
  spec.license      = { :type => "MIT", :file => "LICENSE" }
  spec.author       = { "***" => "***" }

  spec.ios.deployment_target = "16.0"
  spec.swift_version = "5.0"

  spec.source        = { :git => "https://github.com/***/SwiftUIHelper.git", :tag => "#{spec.version}" }
  spec.source_files  = "SwiftHelper/*.{h,m,swift}"

end
