    Sometimes an android can help find the right literature or file very quickly. This is due to the good interaction of Google tools with the services of the operating system. Educational applications and educational resources synergize with voice requests or written requests. This helps to quickly sort consumers to high-frequency queries around the world.

    I had this problem because of UnityPurchasing. At what in one project the assembly worked and there is no other. I copied the UnityChannel and UnityPurchasing folders into a non-working project. After that, the build on ios was successful
