I have been working on an app that makes use of the chart tools. This is now working the way that I want. the Issue now is that when I compile the code in debug and test on a device it is fine. When i biuld an IPA file and sign it with my enterprise agreement the app crashes when I open a page with the chart tool on it. is this because I need to purchase a licence? which I am happy to do just wanted to check this is the issue befor shelling out and not being able to complete my app fully.
