Undefined Symbols when importing with SwiftPM

[Mordil]

Xcode 2.5 (12E262) Swift 5.4 SwiftPM - Xcode's Bundled version Project Minimum iOS Version: 13

filestack-ios: 2.7.2

When importing the library using Xcode's UI for adding Swift Packages to our iOS Target, we add the following code:

import Filestack
import FilestackSDK

extension ViewController {
  private func doSomething() {
    let client = Client(apiKey: "")
    print(client)
  }
}

when we build, Xcode gives us the following errors:

Undefined symbols for architecture arm64:
  "type metadata accessor for FilestackSDK.Client", referenced from:
      Peek_Pro.PKViewOrderViewController.(doSomething in _0192BE462E8B9F880CB09CA425A161D1)() -> () in PKViewOrderViewController.o
  "FilestackSDK.Client.__allocating_init(apiKey: Swift.String, security: FilestackSDK.Security?) -> FilestackSDK.Client", referenced from:
      Peek_Pro.PKViewOrderViewController.(doSomething in _0192BE462E8B9F880CB09CA425A161D1)() -> () in PKViewOrderViewController.o
ld: symbol(s) not found for architecture arm64

Undefined symbol: type metadata accessor for FilestackSDK.Client
Undefined symbol: FilestackSDK.Client.__allocating_init(apiKey: Swift.String, security: FilestackSDK.Security?) -> FilestackSDK.Client

I've narrowed it down to only receiving build errors when importing FilestackSDK, importing Filestack itself is fine
