Communication with Apple failed.

Did you effectively create more that 10 App ID ?
Why would you need when practicing language ?

I don't want to wait

I fear you'll have to wait a full week to create new AppID.
But once again, why would you ?

I don’t know I was changing the appid and it was giving me errors, and I kept retrying then I reached my limit.

Now I cannot compile again because I deleted the old project and created a new one (thought that would solve it) but now I’m stuck for a week.

Is there any way to compile and run without the server authorization?

Try one of your old AppIDs. If you get any errors with it, fix it in the right way. Better clarify what was the error before your retrying.

But I don't want the old appid as my default appid. That's why I changed it in the first place. I didn't even knew that it's restricted to try different appids.

Then wait 7 days. There may be some illegal hacks but Apple would not like such things being discussed in the dev forums.
