iconTint has no effect on shield icon — withTintColor result is discarded

[Talha345]

Description

Setting iconTint in updateShield / ShieldConfiguration has no visible effect. The tint color is silently ignored regardless of what value is passed.

Root Cause

In targets/ShieldConfiguration/ShieldConfigurationExtension.swift, the resolveIcon function calls withTintColor but doesn't assign the result back:

// Current (broken) — result is discarded

  if let iconTint = getColor(color: dict["iconTint"] as? [String: Double]) {
      image?.withTintColor(iconTint)
  }

UIImage.withTintColor(_:) is not a mutating method — it returns a new UIImage. The tinted image is created and immediately thrown away, so image is returned untouched.

Fix

  if let iconTint = getColor(color: dict["iconTint"] as? [String: Double]) {
      image = image?.withTintColor(iconTint, renderingMode: .alwaysOriginal)
  }

Using .alwaysOriginal rendering mode ensures the tint colour is preserved and not overridden by the system.

Steps to Reproduce

1. Call updateShield with any iconSystemName and a non-default iconTint colour
2. Trigger the shield — the icon renders in its default system colour, not the specified tint
