Construct 2 -> Apple App Store process that works currently

Is there a current, working process to submit a Construct2 game to Apple's App Store?

I have viewed, read, and tried many solutions but they all appear to be outdated. I have an iMac, Xcode, and an Apple Developer Account.

I also have three games created in Construct2. I cannot export them to Construct3 because they are missing plugins only available for Construct2.

You don't actually need to convert your C2 to C3 to build a xcode project with C3's build service, therefore you don't have to worry about missing plugins.

Check here for more info and instructions: construct.net/tutorials/using-c3-to-build-c2-mobile-exports-22

If you're doing this for the iPhone X, you'll have a bit more steps, check this tutorial: scirra.com/tutorials/9697/how-to-build-games-from-c2-with-cordova-for-every-platform

Hope this helps :)
